1 Features  
3 Description  
Implements MIPI® D-PHY version 1.00.00 physical  
The SN65DSI83 DSI to FlatLink bridge device  
layer front-end and display serial interface (DSI)  
version 1.02.00  
Single channel DSI receiver configurable for 1, 2,  
3, or 4 D-PHY data lanes per channel operating up  
to 1 Gbps/lane  
Supports 18 bpp and 24 bpp DSI video packets  
with RGB666 and RGB888 formats  
Max resolution up to 60 fps WUXGA  
1920 × 1200 at 18 bpp and 24 bpp color with  
reduced blanking. suitable for 60 fps 1366 × 768 /  
1280 × 800 at 18 bpp and 24 bpp  
FlatLinkoutput for single-link LVDS  
Supports single channel DSI to single-link LVDS  
operating mode  
features a single-channel MIPI D-PHY receiver front-  
end configuration with four lanes per channel  
operating at 1 Gbps per lane; a maximum input  
bandwidth of 4 Gbps. The bridge decodes MIPI DSI  
18 bpp RGB666 and 24 bpp RGB888 packets and  
converts the formatted video data stream to a  
FlatLink-compatible LVDS output operating at pixel  
clocks operating from 25 MHz to 154 MHz, offering a  
Single-Link LVDS with four data lanes per link.  
The SN65DSI83 device can support up to WUXGA  
1920 × 1200 at 60 frames per second, at 24 bpp with  
reduced blanking. The SN65DSI83 device is also  
suitable for applications using 60 fps 1366 × 768 /  
1280 × 800 at 18 bpp and 24 bpp. Partial line  
buffering is implemented to accommodate the data  
stream mismatch between the DSI and LVDS  
interfaces.  
LVDS Output Clock Range of 25 MHz to 154 MHz  
LVDS pixel clock may be sourced from free-  
running continuous D-PHY clock or external  
reference clock (REFCLK)  
Designed  
with  
industry-compliant  
interface  
1.8-V main VCC power supply  
technology, the SN65DSI83 device is compatible with  
a wide range of microprocessors, and is designed  
with a range of power management features including  
low-swing LVDS outputs, and the MIPI defined ultra-  
low power state (ULPS) support.  
Low power features include shutdown mode,  
reduced LVDS output voltage swing, common  
mode, and MIPI ultra-low power state (ULPS)  
support  
LVDS channel swap, LVDS PIN order reverse  
feature for ease of PCB routing  
ESD rating ±2 kV (HBM)  
Packaged in 64-pin 5-mm × 5-mm nFBGA (ZXH)  
Temperature range: –40°C to 85°C  
The SN65DSI83 device is implemented in a small  
outline 5-mm × 5-mm nFBGA at 0.5-mm pitch  
package, and operates across a temperature range  
from –40°C to 85°C.

7.3 Feature Description  
7.3.1 Clock Configurations and Multipliers  
The FlatLink LVDS clock may be derived from the DSI channel A clock, or from an external reference clock  
source. When the MIPI D-PHY channel A HS clock is used as the LVDS clock source, the D-PHY clock lane  
must operate in HS free-running (continuous) mode. This feature eliminates the need for an external reference  
clock reducing system costs  
The reference clock source is selected by HS_CLK_SRC (CSR 0x0A.0) programmed through the local I2C  
interface. If an external reference clock is selected, it is multiplied by the factor in REFCLK_MULTIPLIER (CSR  
0x0B.1:0) to generate the FlatLink LVDS output clock. When an external reference clock is selected, it must be  
between 25 MHz and 154 MHz. If the DSI channel A clock is selected, it is divided by the factor in  
DSI_CLK_DIVIDER (CSR 0x0B.7:3) to generate the FlatLink LVDS output clock. Additionally,  
LVDS_CLK_RANGE (CSR 0x0A.3:1) and CH_DSI_CLK_RANGE(CSR 0x12) must be set to the frequency  
range of the FlatLink LVDS output clock and DSI Channel A input clock respectively for the internal PLL to  
operate correctly. After these settings are programmed, PLL_EN (CSR 0x0D.0) must be set to enable the  
internal PLL.  
7.3.2 ULPS  
The SN65DSI83 device supports the MIPI defined ULPS. While the device is in the ULPS, the CSR registers are  
accessible via I2C interface. ULPS sequence must be issued to all active DSI CLK and, or DSI data lanes of the  
enabled DSI channels for the SN65DSI83 device to enter the ULPS. The following sequence must be followed to  
enter and exit the ULPS.  
1. The host issues a ULPS entry sequence to all DSI CLK and data lanes enabled.  
2. When the host is ready to exit the ULPS mode, the host issues a ULPS exit sequence to all DSI CLK and  
data lanes that need to be active in normal operation.  
3. Wait for the PLL_LOCK bit (CSR 0x0A.7) to be set.  
4. Set the SOFT_RESET bit (CSR 0x09.0).  
5. Device resumes normal operation (that is, video streaming resumes on the panel).  
7.3.3 LVDS Pattern Generation  
The SN65DSI83 device supports a pattern generation feature on LVDS channels. This feature can be used to  
test the LVDS output path and LVDS panels in a system platform. The pattern generation feature can be enabled  
by setting the CHA_TEST_PATTERN bit at address 0x3C. No DSI data is received while the pattern generation  
feature is enabled.  
There are three modes available for LVDS test pattern generation. The mode of test pattern generation is  
determined by register configuration, as shown in Table 7-1.

7.4 Device Functional Modes  
7.4.1 Reset Implementation  
When EN is deasserted (low), the SN65DSI83 device is in shutdown or reset state. In this state, CMOS inputs  
are ignored, the MIPI D-PHY inputs are disabled and outputs are high impedance. It is critical to transition the  
EN input from a low level to a high level after the VCC supply has reached the minimum operating voltage, as  
shown in Figure 7-1. This is achieved by a control signal to the EN input, or by an external capacitor connected  
between EN and GND.  
VCC  
1.65V  
EN  
tVCC  
Figure 7-1. Cold Start VCC Ramp up to EN

When implementing the external capacitor, the size of the external capacitor depends on the power-up ramp of  
the VCC supply, where a slower ramp-up results in a larger value external capacitor. See the latest reference  
schematic for the SN65DSI83 device and, or consider approximately 200-nF capacitor as a reasonable first  
estimate for the size of the external capacitor.  
Both EN implementations are shown in Figure 7-2 and Figure 7-3.

Figure 7-2. External Capacitor Controlled EN  
When the SN65DSI83 is reset while VCC is high, the EN pin must be held low for at least 10 ms before being  
asserted high as described in Table 7-2 to be sure that the device is properly reset. The DSI CLK lane MUST be  
in HS and the DSI data lanes MUST be driven to LP11 while the device is in reset before the EN pin is asserted  
per the timing described in Table 7-2.

7.4.2 Initialization Sequence  
Use the following initialization sequence to setup the SN65DSI83. This sequence is required for proper operation  
of the device. Steps 9 through 11 in the sequence are optional.  
Table 7-2. Initialization Sequence

Wait 10 ms (1)  
Init seq 7  
Set the SOFT_RESET bit (CSR 0x09.0)  
Wait 10 ms (1)  
Init seq 8  
Change DSI data lanes to HS state and start DSI video stream  
Wait 5 ms (1)  
Init seq 9  
Read back all resisters and confirm they were correctly written  
Write 0xFF to CSR 0xE5 to clear the error registers  
Init seq 10  
Wait 1 ms (1)  
Init seq 11  
Read CSR 0xE5. If CSR 0xE5!= 0x00, then go back to step #2 and re-initialize  
(1) Minimum recommended delay. It is fine to exceed these.  
7.4.3 LVDS Output Formats  
The SN65DSI83 device processes DSI packets and produces video data driven to the FlatLink LVDS interface in  
an industry standard format. Single-Link LVDS is supported by the SN65DSI83 device. During conditions such  
as the default condition, and some video synchronization periods, where no video stream data is passing from  
the DSI input to the LVDS output, the SN65DSI83 device transmits zero value pixel data on the LVDS outputs  
while maintaining transmission of the vertical sync and horizontal sync status.  
Figure 7-4 illustrates a Single-Link LVDS 18 bpp application.  
Figure 7-5 illustrates a Single-Link 24 bpp application using Format 2, controlled by CHA_24BPP_FORMAT1  
(CSR 0x18.1). In data Format 2, the two MSB per color are transferred on the Y3P/N LVDS lane.  
Figure 7-6 illustrates a 24 bpp Single-Link application using Format 1. In data Format 1, the two LSB per color  
are transferred on the Y3P/N LVDS lane.  
Figure 7-7 illustrates a Single-Link LVDS application where 24 bpp data is received from DSI and converted to  
18 bpp data for transmission to an 18 bpp panel. This application is configured by setting  
CHA_24BPP_FORMAT1 (CSR 0x18.1) to 1 and CHA_24BPP_MODE (CSR 0x18.3) to 0. In this configuration,  
the SN65DSI83 device does not transmit the 2 LSB per color since the Y3P and Y3N LVDS lane is disabled.  
Note  
Figure 7-4, Figure 7-5, Figure 7-6, and Figure 7-7 only illustrate a few example applications for the  
SN65DSI83 device. Other applications are also supported.

7.4.4 DSI Lane Merging  
The SN65DSI83 device supports four DSI data lanes, and may be configured to support 1, 2, or 3 DSI data  
lanes per channel. Unused DSI input pins on the SN65DSI83 device must be left unconnected or driven to LP11  
state. The bytes received from the data lanes are merged in HS mode to form packets that carry the video  
stream. DSI data lanes are bit and byte aligned.  
Figure 7-8 shows the lane merging function for each channel; 4-, 3-, and 2-lane modes.

7.4.6 DSI Video Transmission Specifications  
The SN65DSI83 device supports burst video mode and non-burst video mode with sync events or with sync  
pulses packet transmission as described in the DSI specification. The burst mode supports time-compressed  
pixel stream packets that leave added time per scan line for power savings LP mode. The SN65DSI83 device  
requires a transition to LP mode once per frame to enable PHY synchronization with the DSI host processor;  
however, for a robust and low-power implementation, the transition to LP mode is recommended on every video  
line.  
Figure 7-12 shows the DSI video transmission applied to SN65DSI83 device applications. In all applications, the  
LVDS output rate must be less than or equal to the DSI input rate. The first line of a video frame shall start with a  
VSS packet, and all other lines start with VSE or HSS. The position of the synchronization packets in time is of  
utmost importance since this has a direct impact on the visual performance of the display panel; that is, these  
packets generate the HS and VS (horizontal and vertical sync) signals on the LVDS interface after the delay  
programmed into CHA_SYNC_DELAY_LOW/HIGH (CSR 0x28.7:0 and 0x29.3:0).  
As required in the DSI specification, the SN65DSI83 device requires that pixel stream packets contain an integer  
number of pixels (that is, end on a pixel boundary); TI recommends to transmit an entire scan line on one pixel  
stream packet. When a scan line is broken in to multiple packets, inter-packet latency shall be considered such  
that the video pipeline (that is, pixel queue or partial line buffer) does not run empty (under-run); during scan line  
processing, if the pixel queue runs empty, the SN65DSI83 device transmits zero data (18’b0 or 24’b0) on the  
LVDS interface.  
Note  
When the HS clock is used as a source for the LVDS pixel clock, the LP mode transitions apply only to  
the data lanes, and the DSI clock lane remains in the HS mode during the entire video transmission.

SN65DSI83 device I2C interface conforms to the 2-wire serial interface defined by the I2C Bus Specification,  
Version 2.1 (January 2000) and supports fast mode transfers up to 400 kbps.  
The device address byte is the first byte received following the start condition from the master device. The 7-bit  
device address for SN65DSI83 device is factory preset to 010110X with the least significant bit being determined  
by the ADDR control input. Table 7-3 clarifies the SN65DSI83 device target address.

(2) When ADDR = 0, Address cycle is 0x58 (write) and 0x59 (read)  
The following procedure is followed to write to the SN65DSI83 device I2C registers:  
1. The master initiates a write operation by generating a start condition (S), followed by the SN65DSI83 device  
7-bit address and a zero-value W/R bit to indicate a write cycle.  
2. The SN65DSI83 device acknowledges the address cycle.  
3. The master presents the subaddress (I2C register within SN65DSI83 device) to be written, consisting of one  
byte of data, MSB-first.  
4. The SN65DSI83 device acknowledges the subaddress cycle.  
5. The master presents the first byte of data to be written to the I2C register.  
6. The SN65DSI83 device acknowledges the byte transfer.  
7. The master may continue presenting additional bytes of data to be written, with each byte transfer completing  
with an acknowledge from the SN65DSI83 device.  
8. The master terminates the write operation by generating a stop condition (P).  
The following procedure is followed to read the SN65DSI83 I2C registers:  
1. The master initiates a read operation by generating a start condition (S), followed by the SN65DSI83 device  
7-bit address and a one-value W/R bit to indicate a read cycle.  
2. The SN65DSI83 device acknowledges the address cycle.  
3. The SN65DSI83 device transmits the contents of the memory registers MSB-first starting at register 00h. If a  
write to the SN65DSI83 I2C register occurred prior to the read, then the SN65DSI83 device starts at the  
subaddress specified in the write.  
4. The SN65DSI83 device waits for either an acknowledge (ACK) or a not-acknowledge (NACK) from the  
master after each byte transfer; the I2C master acknowledges reception of each data byte transfer.  
5. If an ACK is received, the SN65DSI83 device transmits the next byte of data.  
6. The master terminates the read operation by generating a stop condition (P).  
The following procedure is followed for setting a starting subaddress for I2C reads:  
1. The master initiates a write operation by generating a start condition (S), followed by the SN65DSI83 device  
7-bit address and a zero-value W/R bit to indicate a write cycle  
2. The SN65DSI83 device acknowledges the address cycle.  
3. The master presents the subaddress (I2C register within the SN65DSI83 device) to be written, consisting of  
one byte of data, MSB first.  
4. The SN65DSI83 device acknowledges the subaddress cycle.  
5. The master terminates the write operation by generating a stop condition (P).

8 Application and Implementation  
Note  
Information in the following applications sections is not part of the TI component specification, and TI  
does not warrant its accuracy or completeness. TI’s customers are responsible for determining  
suitability of components for their purposes. Customers should validate and test their design  
implementation to confirm system functionality.  
8.1 Application Information  
The SN65DSI83 device is primarily targeted for portable applications such as tablets and smart phones that  
utilize the MIPI DSI video format. The SN65DSI83 device can be used between a GPU with DSI output and a  
video panel with LVDS inputs.  
8.1.1 Video STOP and Restart Sequence  
When the system requires to stop outputting video to the display, TI recommends to use the following sequence  
for the SN65DSI83 device:  
1. Clear the PLL_EN bit to 0 (CSR 0x0D.0).  
2. Stop video streaming on DSI inputs.  
3. Drive all DSI data lanes to LP11, but keep the DSI CLK lanes in HS.  
When the system is ready to restart the video streaming.  
1. Start video streaming on DSI inputs.  
2. Set the PLL_EN bit to 1 (CSR 0x0D.0).  
3. Wait for minimum of 3 ms.  
4. Set the SOFT_RESET bit (0x09.0).  
8.1.2 Reverse LVDS Pin Order Option  
For ease of PCB routing, the SN65DSI83 device supports reversing the pin order via configuration register  
programming. The order of the LVDS pin for LVDS channel A can be reversed by setting the address 0x1A bit 5  
CHA_REVERSE_LVDS. See the corresponding register bit definition for details.  
8.1.3 IRQ Usage  
The SN65DSI83 device provides an IRQ pin that can be used to indicate when certain errors occur on DSI. The  
IRQ output is enabled through the IRQ_EN bit (CSR 0xE0.0). The IRQ pin will be asserted when an error occurs  
on DSI, the corresponding error enable bit is set, and the IRQ_EN bit is set. An error is cleared by writing a 1 to  
the corresponding error status bit.  
Note  
If the SOFT_RESET bit is set while the DSI video stream is active, some of the error status bits may  
be set.  
Note  
If the DSI video stream is stopped, some of the error status bits may be set. These error status bits  
must be cleared before restarting the video stream.  
Note  
If the DSI video stream starts before the device is configured, some of the error status bits may be set.  
TI recommends to start streaming after the device is correctly configured as recommended in the  
initialization sequence in Section 7.4.2.

8.2.2 Detailed Design Procedure  
The video resolution parameters required by the panel need to be programmed into the SN65DSI83 device. For  
this example, the parameters programmed would be the following:  
Horizontal Active = 1280 or 0x500  
CHA_ACTIVE_LINE_LENGTH_LOW = 0x00  
CHA_ACTIVE_LINE_LENGTH_HIGH = 0x05  
Vertical Active = 800 or 0x320  
CHA_VERTICAL_DISPLAY_SIZE_LOW = 0x20  
CHA_VERTICAL_DISPLAY_SIZE_HIGH = 0x03  
Horizontal Pulse Width = 128 or 0x80  
CHA_HSYNC_PULSE_WIDTH_LOW = 0x80  
CHA_HSYNC_PULSE_WIDTH_HIGH = 0x00  
Vertical Pulse Width = 7  
CHA_VSYNC_PULSE_WIDTH_LOW = 0x07  
CHA_VSYNC_PULSE_WIDTH_HIGH = 0x00  
Horizontal Backporch = HorizontalBlanking – (HorizontalSyncOffset + HorizontalSyncPulseWidth)  
Horizontal Backporch = 384 – (64 + 128)  
Horizontal Backporch = 192 or 0xC0  
CHA_HORIZONTAL_BACK_PORCH = 0xC0  
Vertical Backporch = VerticalBlanking – (VerticalSyncOffset +VerticalSyncPulseWidth)  
Vertical Backporch = 30 – (3 + 7)  
Vertical Backporch = 20 or 0x14

The pattern generation feature can be enabled by setting the CHA_TEST_PATTERN bit at address 0x3C and  
configuring the TEST PATTERN GENERATION PURPOSE ONLY register as shown in Table 7-8.  
LVDS clock is derived from the DSI channel A clock. When the MIPI D-PHY channel A HS clock is used as the  
LVDS clock source, it is divided by the factor in DSI_CLK_DIVIDER (CSR 0x0B.7:3) to generate the FlatLink  
LVDS output clock. Additionally, LVDS_CLK_RANGE (CSR 0x0A.3:1) and CH_DSI_CLK_RANGE(CSR 0x12)  
must be set to the frequency range of the FlatLink LVDS output clock and DSI Channel A input clock respectively  
for the internal PLL to operate correctly. After these settings are programmed, PLL_EN (CSR 0x0D.0) must be  
set to enable the internal PLL.  
LVDS_CLK_RANGE = 2 – 62.5 MHz ≤ LVDS_CLK < 87.5 MHz  
HS_CLK_SRC = 1 – LVDS pixel clock derived from MIPI D-PHY channel A  
DSI_CLK_DIVIDER = 00101 – Divide by 6  
CHA_DSI_LANES = 00 – Four lanes are enabled  
CHA_DSI_CLK_RANGE = 0x64 – 500 MHz

9 Power Supply Recommendations  
9.1 VCC Power Supply  
Each VCC power supply pin must have a 100-nF capacitor to ground connected as close as possible to the  
SN65DSI83 device. It is recommended to have one bulk capacitor (1 µF to 10 µF) on it. It is also recommended  
to have the pins connected to a solid power plane.  
9.2 VCORE Power Supply  
This pin must have a 100-nF capacitor to ground connected as close as possible to the SN65DSI83 device. It is  
recommended to have one bulk capacitor (1 µF to 10 µF) on it. It is also recommended to have the pins  
connected to a solid power plane.

10 Layout  
10.1 Layout Guidelines  
10.1.1 Package Specific  
For the ZXH package, to minimize the power supply noise floor, provide good decoupling near the SN65DSI83  
device power pins. The use of four ceramic capacitors (2 × 0.1 μF and 2 × 0.01 μF) provides good performance.  
At the least, TI recommends to install one 0.1-μF and one 0.01-μF capacitor near the SN65DSI83 device. To  
avoid large current loops and trace inductance, the trace length between decoupling capacitor and device power  
inputs pins must be minimized. Placing the capacitor underneath the SN65DSI83 device on the bottom of the  
PCB is often a good choice.

SLLSEC1I – SEPTEMBER 2012 – REVISED OCTOBER 2020  
10.1.2 Differential Pairs  
Differential pairs must be routed with controlled 100-Ω differential impedance (± 20%) or 50-Ω single-ended  
impedance (±15%).  
Keep away from other high speed signals  
Keep lengths to within 5 mils of each other.  
Length matching must be near the location of mismatch.  
Each pair must be separated at least by 3 times the signal trace width.  
The use of bends in differential traces must be kept to a minimum. When bends are used, the number of left  
and right bends must be as equal as possible and the angle of the bend must be ≥ 135 degrees. This  
arrangement minimizes any length mismatch caused by the bends and therefore minimizes the impact that  
bends have on EMI.  
Route all differential pairs on the same of layer.  
The number of vias must be kept to a minimum. It is recommended to keep the via count to 2 or less.  
Keep traces on layers adjacent to ground plane.  
Do NOT route differential pairs over any plane split.  
Adding Test points will cause impedance discontinuity and will therefore negatively impact signal  
performance. If test points are used, they must be placed in series and symmetrically. They must not be  
placed in a manner that causes a stub on the differential pair.  
10.1.3 Ground  
TI recommends that only one board ground plane be used in the design. This provides the best image plane for  
signal traces running above the plane. The thermal pad of the SN65DSI83 must be connected to this plane with  
vias.
