PTN3360D
Enhanced performance HDMI/DVI level shifter with active DDC
buffer, supporting 3 Gbit/s operation
Rev. 4 — 29 June 2012
Product data sheet
1. General description
The PTN3360D 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 v1.4b compliant open-drain
current-steering differential output signals, up to 3.0 Gbit/s per lane to support 36-bit
deep color mode, 4K  2K video format or 3D video data transport. 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
PTN3360D 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 with active
buffering and 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
active I2C-bus buffer technology providing capacitive isolation, redriving and level shifting
as well as disablement (isolation between source and sink) of the clock and data lines.
The low-swing AC-coupled differential input signals to the PTN3360D typically come from
a display source with multi-mode I/O, which supports multiple display standards, for
example, 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 v1.4b specification. By using PTN3360D, 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 PTN3360D main high-speed differential lanes feature low-swing self-biasing
differential inputs which are compliant to the electrical specifications of DisplayPort
Standard v1.2 and/or PCI Express Standard v1.1, and open-drain current-steering
differential outputs compliant to DVI v1.0 and HDMI v1.4b electrical specifications. The
I2C-bus channel actively buffers as well as level-translates the DDC signals for optimal
capacitive isolation. The PTN3360D also supports power-saving modes in order to
minimize current consumption when no display is active or connected.
The PTN3360D is a fully featured HDMI as well as DVI level shifter. The PTN3360D
supersedes PTN3360B, and provides a better high speed performance with a
programmable equalizer.
PTN3360D is powered from a single 3.3 V power supply consuming a small amount of
power (230 mW typical) and is offered in a 48-terminal HVQFN48 package.

HDMI/DVI level shifter supporting 3 Gbit/s operation
7. Functional description
Refer to Figure 2 “Functional diagram of PTN3360D”.
The PTN3360D 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
3.0 Gbit/s per lane to support 36-bit deep color mode. 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 are back-power safe to disallow current flow from a powered sink while the
PTN3360D is unpowered.
The PTN3360D's DDC channel provides active level shifting and buffering, allowing 3.3 V
source-side termination and 5 V sink-side termination. The sink-side DDC ports are
equipped with a rise time accelerator enabling drive of long cables or high bus
capacitance. This enables the system designer to isolate bus capacitance to meet/exceed
HDMI DDC specification. The PTN3360D 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 PTN3360D also provides voltage translation for the Hot Plug Detect (HPD) signal
from 0 V to 5 V on the sink side to 0 V to 3.3 V on the source side.
The PTN3360D does not re-time any data. It contains no state machines. No inputs or
outputs of the device are latched or clocked. Because the PTN3360D acts as a
transparent level shifter, no reset is required.
7.1 Enable and disable features
PTN3360D offers different ways to enable or disable functionality, using the Output
Enable (OE_N), and DDC Enable (DDC_EN) inputs. Whenever the PTN3360D is
disabled, the device will be in Standby mode and power consumption will be minimal;
otherwise the PTN3360D will be in active mode and power consumption will be nominal.
These two inputs each affect the operation of PTN3360D differently: OE_N controls the
TMDS channels, DDC_EN affects only the DDC channel, and 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 PTN3360D 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 mode or Standby mode.

HDMI/DVI level shifter supporting 3 Gbit/s operation
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 signal level has no influence on the HPD_SINK input,
HPD_SOURCE output, or the SCL and SDA level shifters. A transition from HIGH to LOW
at OE_N may disable the DDC channel for up to 20 s.
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 may 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 connected to GND or VDD
directly (0 ). 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 Equalizer

7.4 Backdrive current protection
The PTN3360D 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 PTN3360D is unpowered. In these cases, the
PTN3360D 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 PTN3360D or
that of the inactive DVI or HDMI source.
7.5 Active DDC buffer with rise time accelerator
The PTN3360D DDC channel, besides providing 3.3 V to 5 V level shifting, includes
active buffering and rise time acceleration which allows up to 18 meters bus extension for
reliable DDC applications. While retaining all the operating modes and features of the
I2C-bus system during the level shifts, it permits extension of the I2C-bus by providing
bidirectional buffering for both the data (SDA) and the clock (SCL) line as well as the
rise time accelerator on the sink-side port (SCL_SINK and SDA_SINK) enabling the bus
to drive a load up to 1400 pF or distance of 18 m on the sink-side port, and 400 pF on the
source-side port (SCL_SOURCE and SCA_SOURCE). Using the PTN3360D for DVI or
HDMI level shifting enables the system designer to isolate bus capacitance to
meet/exceed HDMI DDC specification. The SDA and SCL pins are overvoltage tolerant
and are high-impedance when the PTN3360D is unpowered or when DDC_EN is LOW.

HDMI/DVI level shifter supporting 3 Gbit/s operation
PTN3360D has rise time accelerators on the sink-side port (SCL_SINK and SDA_SINK)
only. During positive bus transitions on the sink-side port, a current source is switched on
to quickly slew the SCL_SINK and SDA_SINK lines HIGH once the 5 V DDC bus VIL
threshold level of around 1.5 V is exceeded, and turns off as the 5 V DDC bus VIH
threshold voltage of approximately 3.5 V is approached.

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
