PTN3361C
Enhanced performance HDMI/DVI level shifter with active DDC
buffer, supporting 1.65 Gbit/s operation
Rev. 1.1 — 28 July 2015
Product data sheet
1. General description
PTN3361C 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 1.65 Gbit/s per lane to support 1080p
applications. 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, PTN3361C 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 PTN3361C 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 PTN3361C, 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.
PTN3361C features 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. PTN3361C also supports power-saving
modes in order to minimize current consumption when no display is active or connected.
PTN3361C can be used for either HDMI or DVI level shifting. It provides additional
features supporting HDMI dongle detection; since support of HDMI dongle detection via
the DDC channel is mandatory, the system applications shall enable this feature for
correct operation.
PTN3361C is powered from a single 3.3 V power supply and is offered in a 32-terminal
HVQFN32 package.

HVQFN32 package supply ground is connected to both GND pins and exposed center pad.
GND pins and the exposed center pad 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.

7. Functional description
Refer to Figure 2 “Functional diagram of PTN3361C”.
PTN3361C 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 to support 1080p applications. 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
PTN3361C is unpowered.
PTN3361C'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. Furthermore, the DDC channel is augmented with an I2C-bus
slave ROM device that provides optional HDMI dongle detect response, which can be
enabled by Dongle detect signal DDET. PTN3361C 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.
PTN3361C 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.
PTN3361C does not re-time any data. It contains no state machines. No inputs or outputs
of the device are latched or clocked. Because PTN3361C acts as a transparent level
shifter, no reset is required.
Remark: When used in an HDMI dongle, the DDET function must be enabled for correct
operation. When used in a DVI dongle, the DDET function must be disabled.
7.1 Enable and disable features
PTN3361C offers different ways to enable or disable functionality, using the Output
Enable (OE_N), and DDC Enable (DDC_EN) inputs. Whenever PTN3361C is disabled,
the device will be in Standby mode and power consumption will be minimal; otherwise
PTN3361C will be in active mode and power consumption will be nominal. These two
inputs each affect the operation of PTN3361C 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 PTN3361C 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.

NXP Semiconductors
HDMI/DVI level shifter supporting 1.65 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
PTN3361C supports 3 level equalization setting by the quinary input pin EQ3.

7.4 Backdrive current protection
PTN3361C 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 PTN3361C is unpowered. In these cases, PTN3361C 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 PTN3361C or that of the inactive DVI
or HDMI source.
7.5 Active DDC buffer with rise time accelerator
PTN3361C 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 PTN3361C 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 PTN3361C is unpowered or when DDC_EN is LOW.
PTN3361C 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.

7.6 I2C-bus based HDMI dongle detection
PTN3361C includes an on-board I2C-bus slave ROM which provides a means to detect
the presence of an HDMI dongle by the system through the DDC channel, accessible via
ports SDA_SOURCE and SCL_SOURCE. This allows system vendors to detect HDMI
dongle presence through the already available DDC/I2C-bus port using a predetermined
bus sequence. Please see Section 8 for more information.
For the I2C-bus HDMI Dongle Detect function to be active, input pin DDET (dongle detect)
should be tied HIGH. When DDET is LOW, PTN3361C will not respond to an I2C-bus
command. When used in an HDMI dongle, the DDET function must be enabled for
correct operation in accordance with DisplayPort interoperability guidelines. When used in
a DVI dongle, the DDET function must be disabled.
The HDMI dongle detection is accomplished by accessing PTN3361C on-board I2C-bus
slave ROM using a simple sequential I2C-bus Read operation as described below.

7.6.2 Read operation
The slave device address of PTN3361C is 80h. PTN3361C will respond to a Read
command to slave address 81h (PTN3361C will respond with an ACK to a Write
command to address 80h). Following the Read command, PTN3361C will respond with
the contents of its internal ROM, as a sequence of 16 bytes, for as long as the master
continues to issue clock edges with an acknowledge after each byte. The 16-byte
sequence represents the ‘DP-HDMI ADAPTOR’ symbol converted to ASCII and is
documented in Table 6.
PTN3361C auto-increments its internal ROM address pointer (0h through Fh) as long as it
continues to receive clock edges from the master with an acknowledge after each byte. If
the master continues to issue clock edges past the 16th byte, PTN3361C will respond with
a data byte of FFh. If the master does not acknowledge a received byte, PTN3361C
internal address pointer will be reset to 0 and a new Read sequence should be started by
the master. Access to the 16-byte is by sequential read only as described above; there is
no random-access possible to any specific byte in the ROM.

7.7 Characteristics of the I2C-bus
The I2C-bus is for 2-way, 2-line communication between different ICs or modules. The two
lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be
connected to a positive supply via a pull-up resistor when connected to the output stages
of a device. Data transfer may be initiated only when the bus is not busy.
7.7.1 Bit transfer
One data bit is transferred during each clock phase. The data on the SDA line must
remain stable during the HIGH period of the clock pulse as changes in the data line at this
time will be interpreted as control signals (see Figure 5).

7.7.2 START and STOP conditions
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW
transition of the data line, while the clock is HIGH is defined as the START condition (S). A
LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP
condition (P). See Figure 6.

7.7.3 System configuration
An I2C-bus device generating a message is a ‘transmitter’, a device receiving is the
‘receiver’. The device that controls the message is the ‘master’ and the devices which are
controlled by the master are the ‘slaves’. See Figure 7.

7.7.4 Acknowledge
The number of data bytes transferred between the START and the STOP conditions from
transmitter to receiver is not limited. Each byte of eight bits is followed by one
acknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter,
whereas the master generates an extra acknowledge related clock pulse.
A slave receiver which is addressed must generate an acknowledge after the reception of
each byte. Also, a master must generate an acknowledge after the reception of each byte
that has been clocked out of the slave transmitter. The device that acknowledges has to
pull down the SDA line during the acknowledge clock pulse so that the SDA line is stable
LOW during the HIGH period of the acknowledge related clock pulse, set-up and hold
times must be taken into account.
A master receiver must signal an end of data to the transmitter by not generating as
acknowledge on the last byte that has been clocked out of the slave. In this event, the
transmitter must leave the data line HIGH to enable the master to generate a STOP
condition.

8. Application design-in information
8.1 Dongle or cable adaptor detect discovery mechanism
PTN3361C supports the source-side dongle detect discovery mechanism described in
VESA DisplayPort Interoperability Guideline Version 1.1.
When a source-side cable adaptor is plugged into a multi-mode source device that
supports multiple standards such as DisplayPort, DVI and HDMI, a discovery mechanism
is needed for the multi-mode source to configure itself for outputting DisplayPort, DVI or
HDMI compliant signals through the dongle or cable adaptor. The discovery mechanism
ensures that a multi-mode source device only sends either DVI or HDMI signals when a
valid DVI or HDMI cable adaptor is present.
The VESA Interoperability Guideline recommends that a multi-mode source to power up
with both DDC and AUX CH disabled. After initialization, the source device can use a
variety of mechanisms to decide whether a dongle or cable adaptor is present by
detecting pin 13 on the DisplayPort connector. Depending on the voltage level detected at
pin 13, the source configures itself either:
• as a DVI or HDMI source (see below paragraph for detection between DVI and
HDMI), and enables DDC, while keeping AUX CH disabled, or
• as a DisplayPort source and enables AUX CH, while keeping DDC disabled.
The monitoring of the voltage level on pin 13 by a multi-mode source device is optional. A
multi-mode source may also e.g. attempt an AUX CH read transaction and, if the
transaction fails, a DDC transaction to discover the presence/absence of a cable adaptor.
Furthermore, a source that supports both DVI and HDMI can discover whether a DVI or
HDMI dongle or cable adaptor is present by using a variety of discovery procedures. One
possible method is to check the voltage level of pin 14 of the DisplayPort connector.
Pin 14 also carries CEC signal used for HDMI. Please note that other HDMI devices on
the CEC line may be momentarily pulling down pin 14 as a part of CEC protocol.
The VESA Interoperability Guideline recommends that a multi-mode source should
distinguish a source-side HDMI cable adaptor from a DVI cable adaptor by checking the
DDC buffer ID as described in Section 7.6 “I2C-bus based HDMI dongle detection”. While
it is optional for a multi-mode source to use the I2C-bus based HDMI dongle detection
mechanism, it is mandatory for HDMI dongle or cable adaptor to respond to the I2C-bus
read command described in Section 7.7. PTN3361C provides an integrated I2C-bus slave
ROM to support this mandatory HDMI dongle detect mechanism for HDMI dongles.
For a DisplayPort-to-HDMI source-side dongle or cable adaptor, DDET must be tied HIGH
to enable the I2C-bus based HDMI dongle detection response function of PTN3361C. For
a DisplayPort-to-DVI sink-side dongle or cable adaptor, DDET must be tied LOW to
disable the function.

13. 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”.
13.1 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.
13.2 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
13.3 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

13.4 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 10) 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 16 and 17

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 10.
