FEATURES  
DESCRIPTION  
The DS90CF383B transmitter converts 28 bits of  
CMOS/TTL data into four LVDS (Low Voltage  
Differential Signaling) data streams. A phase-locked  
transmit clock is transmitted in parallel with the data  
streams over a fifth LVDS link. Every cycle of the  
transmit clock 28 bits of input data are sampled and  
transmitted. At a transmit clock frequency of 65 MHz,  
24 bits of RGB data and 3 bits of LCD timing and  
control data (FPLINE, FPFRAME, DRDY) are  
transmitted at a rate of 455 Mbps per LVDS data  
channel. Using a 65 MHz clock, the data throughput  
is 227 Mbytes/sec. The DS90CF383B is fixed as a  
Falling edge strobe transmitter and will interoperate  
with a Falling edge strobe Receiver (DS90CF386)  
without any translation logic.

The worst case test pattern produces a maximum toggling of digital circuits, LVDS I/O and CMOS/TTL I/O.  
The 16 grayscale test pattern tests device power consumption for a “typical” LCD display pattern. The test pattern  
approximates signal switching needed to produce groups of 16 vertical stripes across the display.  
Figure 1 and Figure 2 show a falling edge data strobe (TxCLK IN/RxCLK OUT).

SNLS178E JULY 2004REVISED APRIL 2013  
APPLICATIONS INFORMATION  
The DS90CF383B are backward compatible with the DS90C383/DS90CF383, DS90C383A/DS90CF383A and  
are a pin-for-pin replacement.  
This device may also be used as a replacement for the DS90CF583 (5V, 65MHz) and DS90CF581 (5V, 40MHz)  
FPD-Link Transmitters with certain considerations/modifications:  
1. Change 5V power supply to 3.3V. Provide this supply to the VCC, LVDS VCC and PLL VCC of the transmitter.  
TRANSMITTER INPUT PINS  
The DS90CF383B transmitter input and control inputs accept 3.3V LVTTL/LVCMOS levels. They are not 5V  
tolerant.  
TRANSMITTER CLOCK CLOCK/DATA SEQUENCING  
The DS90CF383B does not require any special requirement for sequencing of the input clock/data and PD  
(PowerDown) signal. The DS90CF383B offers a more robust input sequencing feature where the input clock/data  
can be inserted after the release of the PD signal. In the case where the clock/data is stopped and reapplied,  
such as changing video mode within Graphics Controller, it is not necessary to cycle the PD signal. However,  
there are in certain cases where the PD may need to be asserted during these mode changes. In cases where  
the source (Graphics Source) may be supplying an unstable clock or spurious noisy clock output to the LVDS  
transmitter, the LVDS Transmitter may attempt to lock onto this unstable clock signal but is unable to do so due  
the instability or quality of the clock source. The PD signal in these cases should then be asserted once a stable  
clock is applied to the LVDS transmitter. Asserting the PWR DOWN pin will effectively place the device in reset  
and disable the PLL, enabling the LVDS Transmitter into a power saving standby mode. However, it is still  
generally a good practice to assert the PWR DOWN pin or reset the LVDS transmitter whenever the clock/data is  
stopped and reapplied but it is not mandatory for the DS90CF383B.  
SPREAD SPECTRUM CLOCK SUPPORT  
The DS90CF383B can support Spread Spectrum Clocking signal type inputs. The DS90CF383B outputs will  
accurately track Spread Spectrum Clock/Data inputs with modulation frequencies of up to 100KHz (max.)with  
either center spread of ±2.5% or down spread -5% deviations.  
POWER SOURCES SEQUENCE  
In typical applications, it is recommended to have VCC, LVDS VCC and PLL VCC from the same power source with  
three separate de-coupling bypass capacitor groups. There is no requirement on which VCC entering the device  
first.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
