PTN3355
Low power DisplayPort to VGA adapter with integrated
1 : 2 VGA switch
Rev. 3 — 14 July 2014
Product data sheet
1. General description
PTN3355 is a DisplayPort to VGA adapter with an integrated 1 : 2 VGA switch optimized
primarily for motherboard applications, to convert a DisplayPort signal from the chip set to
an analog video signal that directly connects to the VGA connector. PTN3355 integrates a
DisplayPort receiver, a high-speed triple video digital-to-analog converter and 1 : 2 VGA
switch that supports a wide range of display resolutions, for example, VGA to WUXGA
(see Table 9). PTN3355 supports either one or two DisplayPort lanes operating at either
2.7 Gbit/s or 1.62 Gbit/s per lane.
PTN3355 supports I2C-bus over AUX per DisplayPort standard (Ref. 1), and bridges the
VESA DDC channel to the DisplayPort Interface.
PTN3355 is powered from a 3.3 V power supply and consumes approximately 200 mW of
power for video streaming in WUXGA resolution and 410 W of power in Low-power
mode. The VGA output is powered down when there is no valid DisplayPort source data
being transmitted. PTN3355 also aids in monitor detection by performing load sensing on
RGB lines and reporting sink connection status to the source.

Low power DP to VGA adapter with integrated 1 : 2 VGA switch
7. Functional description
Referring to Figure 1 “Functional diagram”, the PTN3355 performs protocol conversion
from VESA DisplayPort specification to VESA VGA output. At the physical layer, PTN3355
implements the advanced DisplayPort Front-end technology (Auto receive equalization,
Clock Data Recovery) to support the objectives of delivering excellent Signal Integrity (SI)
performance, and consuming very low power consumption. The PTN3355 integrates a
DisplayPort receiver (according to VESA DisplayPort standard, Ref. 1) and a high-speed
triple 8-bit video digital-to-analog converter that supports a wide range of video resolutions
(see Table 9 “Display resolution and pixel clock rate[1]”), up to a pixel clock rate of
240 MHz. The PTN3355 supports one or two DisplayPort Main Link lanes operating at
either in 2.7 Gbit/s or 1.62 Gbit/s per lane. PTN3355 also integrates a 1 : 2 VGA switch
that enables driving VGA signals either to main board connector or docking connector.
This feature helps realize BOM saving due to removal of discrete VGA switch component.
PTN3355 comprises the following functional blocks:
•
•
•
•
•
•
DP Main Link
DP AUX CH (Auxiliary Channel)
DPCD (DisplayPort Configuration Data)
VGA monitor detection
Video DAC
1 : 2 VGA switch
The RGB video data with corresponding synchronization references are extracted from
the main stream video data. Main stream video attribute information is also extracted. This
information is inserted once per video frame during the vertical blanking period by the DP
source. The attributes describe the main video stream format in terms of geometry, timing,
and color format. The original video clock and video stream are derived from these main
link data.
The PTN3355 internal DPCD registers can be accessed by the DP source via the
DP AUX channel. The monitor’s DDC control bus may also be controlled via the DP AUX
channel. PTN3355 implements the standard DisplayPort I2C-over-AUX protocol
conversion to provide DP source access to the VGA plug DDC-I2C interface. The
PTN3355 passes through sink-side status change (for example, hot-plug events) to the
source side, through HPD interrupts and DPCD registers.
PTN3355 integrates a 1 : 2 VGA switch that selects between the two channels, depending
on DOCK_IN setting. Also, PTN3355 provides a slave I2C-bus interface for reading and
updating configuration registers. These registers and their settings are described in a
separate document.
7.1 DisplayPort Main Link
The DisplayPort main link consists of two AC-coupled differential pairs. The 50 
termination resistors are integrated inside PTN3355.
The PTN3355 supports HBR at 2.7 Gbit/s and RBR at 1.62 Gbit/s per lane.

Low power DP to VGA adapter with integrated 1 : 2 VGA switch
7.2 DisplayPort auxiliary channel (AUX CH)
The AUX CH is a half-duplex, bidirectional channel between DisplayPort source and sink.
It consists of one differential pair transporting self-clocked data at 1 Mbit/s. The PTN3355
integrates the AUX CH replier (or slave), and responds to transactions initiated by the
DisplayPort source AUX CH requester (or master).
The AUX CH uses the Manchester-II code for the self-clocked transmission of signals;
every ‘zero’ is represented by LOW-to-HIGH transition, and ‘one’ represented by
HIGH-to-LOW transition, in the middle of the bit time.
7.3 DPCD registers
DPCD registers that are part of the VESA DisplayPort standard are described in detail in
Ref. 1. The following describes the specific implementation by PTN3355 only.
PTN3355 DisplayPort receiver capability and status information about the link are
reported by DisplayPort Configuration Data (DPCD) registers, when a DP source issues a
read command on the AUX CH. The DP source device can also write to the link
configuration field of DPCD to configure and initialize the link. The DPCD is DisplayPort
v1.2a compliant.
PTN3355 specific capabilities are made available to DP source in the relevant DPCD
read/write registers. In line with the DisplayPort standard (Ref. 1), the specific Link
controls are also made available to initialize and maintain the DisplayPort Link.
It is the responsibility of the DP source to issue commands only within the capability of the
PTN3355 as defined in the ‘Receiver Capability Field’ in order to prevent undefined
behavior. PTN3355 specific DPCD registers are listed in Table 4.

7.4 VGA monitor detection
The PTN3355 implements a robust scheme for VGA monitor detection. It senses
presence or absence of VGA monitor load termination (75 ) by pulsing the RGB lines.
The load sensing operation is performed periodically to determine the latest VGA
connectivity status. If the VGA monitor is disconnected, then the detection logic informs
the host platform via IRQ_HPD signal.
7.5 EDID handling
Figure 3 shows a DisplayPort-to-analog video converter between the DisplayPort source
and a VGA monitor. The PTN3355 implements a DP I2C-Over-AUX protocol, providing for
DP source access to the monitor’s DDC bus. With this, the monitor’s EDID data is made
available to DP source for access at any time.
It is the responsibility of the source to choose only video modes which are declared in the
EDID and to adjust the DisplayPort link capabilities (link rate and lane count) to provide
the necessary video bandwidth. The PTN3355 does not cache or modify the EDID to
match the capabilities of the DisplayPort link data.
If the DisplayPort source drives display modes that are not specified in the EDID mode
list, the PTN3355 does not detect such conditions, and it depends entirely on the VGA
display on what is being displayed.

7.6 Triple 8-bit video DACs and VGA outputs
The triple 8-bit video DACs output a 700 mV (peak-to-peak) analog video output signal
into 37.5  load, as is the case of a doubly terminated 75  cable. The DAC is capable of
supporting the maximum pixel rate supported by a two-lane DP link (240 MHz).
7.6.1 DAC reference resistor
An external reference resistor must be connected between pin RSET and ground. This
resistor sets the reference current which determines the analog output level, and is
specified as 1.2 k with a 1 % tolerance. This value allows a 0.7 V (peak-to-peak) output
into a 37.5  load (for example, double-terminated 75  coaxial cable).

Low power DP to VGA adapter with integrated 1 : 2 VGA switch
8. Power-up and reset
PTN3355 has built-in power-on reset circuitry which automatically sequences the part
through reset and initialization. In addition, there is a dedicated pin (RST_N) to
control/effect reset operation externally. This provides flexibility at the platform level for
debug or application purpose.
Before link is established, the PTN3355 holds VSYNC and HSYNC signals LOW and
blanks the RGB signals.
While the PTN3355 performs power-on initialization,
• The HPD signal is driven LOW, to indicate to the DisplayPort source that the
PTN3355 is not ready for AUX channel communication. Once the device is initialized,
the HPD level is produced based on CFG1_SCL/CFG2_SDA setting
• The RGB outputs are disabled
• The VSYNC and HSYNC outputs are maintained LOW as long as there is no active
video streaming from the DisplayPort source.
9. Configurability and programmability
The PTN3355 delivers flexibility for application usage by providing configurability via two
options:
• Configuration pins CFG1_SCL, CFG2_SDA, CFG5, DOCK_IN and TESTMODE
• DP-AUX vendor-specific configuration registers
The pins provide limited application board level configurability, whereas vendor-specific
configuration registers deliver ultimate flexibility. The configuration pin changes (static,
dynamic) are reflected in the IC behavior.
The configuration pin definitions are as follows:
• CFG1_SCL, CFG2_SDA are used for either host I2C communication or as dedicated
configuration pins with binary leveled I/O. PTN3355 is flexible to accept either. The
use of these configuration pins is defined in Table 8.
• Configuration pin CFG5 selects OSC_IN clock frequency setting. Table 5 captures the
pin definition.

The TESTMODE pin is used to indicate selection of JTAG or Configuration/I2C mode for
CFG1_SCL, CFG2_SDA and CFG5. Table 7 defines the possible combinations of
TESTMODE pin.

CFG1_SCL, CFG2_SDA can be used in I2C mode or configuration pin mode. PTN3355
automatically detects the mode in which these pins are used. If they are used as
Configuration pins, Table 8 determines the possible and allowed combinations for these
pin settings. If they are used as I2C Clock/Data pins, PTN3355 detects toggling of the pins
during I2C data transport and receives data properly.

More configuration options are available through internal configuration registers. These
registers can be accessed by GPU/CPU software driver via DP AUX channel or I2C-bus.
NXP can deliver Windows and DOS based utilities, on explicit request, to upgrade the
firmware or configuration registers only for laboratory evaluation and debugging purposes
at customer premises.
10. Application design-in information
With its maximum integration features, the PTN3355 has low BOM requirement at the
platform application level. Figure 4 illustrates the PTN3355 usage in a system application
context. On the DP side, it is connected to DP source and the VGA side, it is connected to
VGA connector. The PTN3355 system application requires the following components
additionally: supply decoupling capacitors, DC blocking capacitors, pull-up/down resistors,
(optional) inductor for DC-to-DC converter, crystal oscillator. For more details on reference
design information, contact NXP team.

10.2 Power supply filter
Sufficient decoupling capacitance to ground should be connected from each VDD pin
directly to ground to filter supply noise.
10.3 DAC terminations
Typically, the VGA RGB outputs are (doubly) terminated. Figure 6 shows an example
VGA application. A 75  termination is used to terminate inside the motherboard, and
another 75  termination is typically used inside the RGB monitor. The load sensing
mechanism assumes this double termination. Figure 7 is another example of VGA
application with 50  PCB trace impedance with 150  terminations.
In general, it is left to the system integrator to decide on their specific implementation.

10.4 Timing reference
PTN3355 requires a crystal or ceramic resonator for a stable VGA clock timing reference.
Resonators have a higher frequency tolerance than crystals, but have the advantage of
integrated capacitors and therefore a small PCB area and potentially lower cost.

16. 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”.
16.1 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.
16.2 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

Low power DP to VGA adapter with integrated 1 : 2 VGA switch
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
16.3 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
16.4 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 15) 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 27 and 28
