PTN3380B
DVI level shifter with voltage regulator
Rev. 2 — 1 February 2011
Product data sheet
1. General description
The PTN3380B is a high-speed level shifter device which converts four lanes of low-swing
AC-coupled differential input signals to DVI v1.0 and HDMI v1.3a compliant open-drain
current-steering differential output signals, up to 1.65 Gbit/s per lane. Each of these lanes
provides a level-shifting differential buffer to translate from low-swing AC-coupled
differential signaling on the source side, to TMDS-type DC-coupled differential
current-mode signaling terminated into 50 to 3.3 V on the sink side. Additionally, the
PTN3380B provides a single-ended active buffer for voltage translation of the HPD signal
from 5 V on the sink side to 3.3 V on the source side and provides a channel for level
shifting of the DDC channel (consisting of a clock and a data line) between 3.3 V
source-side and 5 V sink-side. The DDC channel is implemented using pass-gate
technology providing level shifting as well as disablement (isolation between source and
sink) of the clock and data lines.
To provide the highest level of integration in external adapter (or: dongle) applications,
PTN3380B includes an on-board 5 V DC regulator. Its output is designed to provide the
required 5 V power supply to the DVI connector, thereby eliminating the need for a
separate external regulator. The on-board regulator needs only two external capacitors to
operate, and its output is active whenever a valid 3.3 V is applied to the PTN3380B VDD
pins.
The low-swing AC-coupled differential input signals to the PTN3380B typically come from
a display source with multi-mode I/O, which supports multiple display standards, e.g.,
DisplayPort, HDMI and DVI. While the input differential signals are configured to carry DVI
or HDMI coded data, they do not comply with the electrical requirements of the DVI v1.0
or HDMI v1.3a specification. By using PTN3380B, chip set vendors are able to implement
such reconfigurable I/Os on multi-mode display source devices, allowing the support of
multiple display standards while keeping the number of chip set I/O pins low. See
Figure 1.
The PTN3380B main high-speed differential lanes feature low-swing self-biasing
differential inputs which are compliant to the electrical specifications of DisplayPort
Standard v1.1 and/or PCI Express Standard v1.1, and open-drain current-steering
differential outputs compliant to DVI v1.0 and HDMI v1.3a electrical specifications. The
I2C-bus channel level-translates the DDC signals between 3.3 V (source) and 5.0 V (sink).
The PTN3380B is a fully featured DVI level shifter. It is functionally comparable to
PTN3360B but provides an onboard 5 V regulator.
PTN3380B is powered from a single 3.3 V power supply consuming a small amount of
power (100 mW typical with no load at 5 V regulator) and is offered in a 48-terminal
HVQFN48 package.

HVQFN48 package supply ground is connected to both GND pins and exposed center pad. GND
pins must be connected to supply ground for proper device operation. For enhanced thermal,
electrical, and board level performance, the exposed pad needs to be soldered to the board using
a corresponding thermal pad on the board and for proper heat conduction through the board,
thermal vias need to be incorporated in the PCB in the thermal pad region.

DVI level shifter with voltage regulator
7. Functional description
Refer to Figure 2 “Functional diagram of PTN3380B”.
The PTN3380B level shifts four lanes of low-swing AC-coupled differential input signals to
DVI and HDMI compliant open-drain current-steering differential output signals, up to
1.65 Gbit/s per lane. It has integrated 50 termination resistors for AC-coupled
differential input signals. An enable signal OE_N can be used to turn off the TMDS inputs
and outputs, thereby minimizing power consumption. The TMDS outputs, HPD_SINK
input and DDC_SINK I/Os are back-power safe to disallow current flow from a powered
sink while the PTN3380B is unpowered.
The PTN3380B's DDC channel provides passive level shifting, allowing 3.3 V source-side
termination and 5 V sink-side termination. The PTN3380B offers back-power safe
sink-side I/Os to disallow backdrive current from the DDC clock and data lines when
power is off or when DDC is not enabled. An enable signal DCC_EN enables the DDC
level shifter block.
The PTN3380B also provides voltage translation for the Hot Plug Detect (HPD) signal
from 0 V to 5 V on the sink side, non-inverting and level-shifting to 0 V or 3.3 V on the
source side.
PTN3380B includes an onboard 5 V DC regulator, designed to provide the required 5 V
power supply to the DVI connector, thereby eliminating the need for a separate external
regulator. The onboard regulator needs only two external capacitors to operate, and its
output is active whenever a valid 3.3 V is applied to the PTN3380B VDD pins. The back
drive protection on 5 V output prevents back-drive current from 5 V output to the input
supply. The short-circuit protection limits current flowing through the supply, and the
overcurrent protection prevents overload conditions at the charge pump output.
The PTN3380B does not re-time any data. It contains no state machines except for the
DDC/I2C-bus block. No inputs or outputs of the device are latched or clocked. Because
the PTN3380B acts as a transparent level shifter, no reset is required.
7.1 Enable and disable features
PTN3380B offers different ways to enable or disable functionality, using the Output Enable
(OE_N) and DDC Enable (DDC_EN) inputs. Whenever the PTN3380B is disabled, the
device will be in Standby mode and power consumption will be minimal; otherwise the
PTN3380B will be in active mode and power consumption will be nominal. These two
inputs each affect the operation of PTN3380B differently: OE_N affects only the TMDS
channels, and DDC_EN affects only the DDC channel. HPD_SINK does not affect either
of the channels. The following sections and truth table describe their detailed operation.
7.1.1 Hot plug detect
The HPD channel of PTN3380B functions as a level-shifting buffer to pass the HPD logic
signal from the display sink device (via input HPD_SINK) on to the display source device
(via output HPD_SOURCE).
The output logic state of HPD_SOURCE output always follows the logic state of input
HPD_SINK, regardless of whether the device is in Active or Standby mode.

7.1.2 Output Enable function (OE_N)
When input OE_N is asserted (active LOW), the IN_Dx and OUT_Dx signals are fully
functional. Input termination resistors are enabled and the internal bias circuits are turned
on.
When OE_N is de-asserted (inactive HIGH), the OUT_Dx outputs are in a
high-impedance state and drive zero output current. The IN_Dx input buffers are disabled
and IN_Dx termination is disabled. Power consumption is minimized.
Remark: Note that OE_N has no influence on the HPD_SINK input, HPD_SOURCE
output, or the SCL and SDA level shifters. OE_N only affects the high-speed TMDS
channel.
7.1.3 DDC channel enable function (DDC_EN)
The DDC_EN pin is active HIGH and can be used to isolate a badly behaved slave. When
DDC_EN is LOW, the DDC channel is turned off. The DDC_EN input should never
change state during an I2C-bus operation. Note that disabling DDC_EN during a bus
operation will hang the bus, while enabling DDC_EN during bus traffic would corrupt the
I2C-bus operation. Hence, DDC_EN should only be toggled while the bus is idle. (See
I2C-bus specification).

7.2 Analog current reference
The REXT pin (pin 6) is an analog current sense port used to provide an accurate current
reference for the differential outputs OUT_Dx. For best output voltage swing accuracy,
use of a 10 k resistor (1 % tolerance) connected between this terminal and GND is
recommended.
If an external 10 k 1 % resistor is not used, this pin can be left open-circuit, or
connected to GND or VDD, either directly (0 ) or using pull-up or pull-down resistors of
value less than 10 k. In any of these cases, the output will function normally but at
reduced accuracy over voltage and temperature of the following parameters: output levels
(VOL), differential output voltage swing, and rise and fall time accuracy.
7.3 Backdrive current protection
The PTN3380B is designed for backdrive prevention on all sink-side TMDS outputs,
sink-side DDC I/Os and the HPD_SINK input. This supports user scenarios where the
display is connected and powered, but the PTN3380B is unpowered. In these cases, the
PTN3380B will sink no more than a negligible amount of leakage current, and will block
the display (sink) termination network from driving the power supply of the PTN3380B or
that of the inactive DVI or HDMI source.

12. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
12.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
12.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation
• The moisture sensitivity level of the packages
• Package placement
• Inspection and repair
• Lead-free soldering versus SnPb soldering
12.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

12.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 5) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 13 and 14

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 5.
