1 Overview
1.1 What is the DP159?
The DP159 is a Dual-Mode DisplayPort to Transition Minimized Differential Signal (TMDS) retimer
supporting Digital Video Interface (DVI) 1.0 and High Definition Multimedia Interface (HDMI) 1.4b and 2.0
output signals. The DP159 supports the Dual-Mode Standard version 1.1 type 1 and type 2 through the
DDC link. The DP159 supports data rates up to 6 Gbps per data lane to support UltraHD (4K x 2K / 60
Hz) 8 bits per color high resolution video and HDTV with 16-bit color depth at 1080p (1920 x 1080 / 60
Hz). The DP159 can automatically configure itself as a redriver at data rates < 1.0 Gbps or as a retimer
above this data rate.
1.2 What is the DP159RGZEVM?
The DP159RGZEVM is a PCB created to help customers evaluate the DP159 device for video
applications. This EVM can also be used as a hardware reference design for implementation of the DP159
in the RSB package. PCB design/layout files can be provided upon request to provide PCB design
illustrations of the routing/placement rules.
Note that the EVM design supports both the standard DP159 application and a DP159-thru-HDMI
application, so it contains many components that would not be needed by a typical DP159 application. A
separate reference design specific to the DP159 is available for customers.
1.3 What is Included in the DP159RGZEVM?
The major components of the EVM are as follows:
• DP159RGZ
• Standard DP sink connector (connects to source)
• Standard HDMI source connector (connects to sink)
• DC power regulators
• I2C™ programming interface for external I2C host connection
• USB interface (I2C utility available)

DP159RGZ Evaluation Module
2.1 Video Connectors for DP159 Ports
The EVM has a DP connection for the source and a HDMI connection for the sink. J2 is a standard DP
connector (Molex 47272-0001). P2 is a standard HDMI connector (Molex 4715-10001). There is a third
video connection on the board for a HDMI source (P1), this function is not installed on the
DP159RGZEVM.
2.2 Enable/Reset
There are three device enable/reset options to use with the EVM:
A. Supervisor circuitry option
This is the default configuration on the DP159RGZEVM. The enable (EN) signal is held low until the
power good (PG) from the 3.3-V voltage regulator reaches a stable high-voltage level then released
high.
B. RC timing option
C26 external capacitor and internal resistor are used to control the EN ramp time after the device is
powered on. C26 is a Do Not Install (DNI option) by default. C26 needs to be installed and R77 needs
to be uninstalled to enable this option.
C. External control option
A push button (SW1) is provided for manual control of the DP159’s EN/OE input.
2.3 Power
A DC power jack (J9) to accept a 5-V wall power adapter is provided on the EVM. The DC power jack
(CUI Inc. PJ-202AH) has an inner diameter of 2.1 mm and an outer diameter of 5.5 mm. The tip of the +5-
V power supply must be positive. A +5-V power supply of at least 1.5 A that meets the given requirements
can be used to power the DP159RGZEVM. Power is provided to the EVM from the 5-V wall power
adapter when SW2 is set to position 1.
CAUTION
Care should be taken to not plug in any power source higher than the
configured voltage (5 V).
Alternately, it is possible to power the EVM by connecting a USB Micro cable from J13 to a USB host and
setting SW2 to position 3.

2.5 Component Population Configuration
To allow the DP159RGZEVM to support both the default DP input as well as a HDMI test input, there are
many components that need to be removed, placed, or modified depending on the board configuration.
Here’s a summary of the default component configuration for the DP159RGZEVM. In addition, the unused
HDMI receptacle is depopulated.
Function Reference Designator DP159RGZEVM
Differential Pair - IN C11, C12, C13, C14, C15, C16, C24,
C25 populated with 0.1 µF
Differential Pair - HDMI IN R14, R15, R18, R19, R20, R21, R22,

SDA / SCL - HDMI R16, R17, R24, R25, R123, R124 not populated
Differential Pair - DP IN R112, R109, R111, R108, R110, R107,
R106, R105 populated with 0 Ω
SDA / SCL / HPD - DP R33, R31, R32 (R126, R135, R132,
R133 - snoop) populated with 0 Ω
Pullup Differential Pair HDMI IN R1, R2, R3, R4, R6, R7, R8, R9 populated, but not
connected
2.5.1 HPD Snoop Option
To accommodate systems that do not properly resend DDC commands after HPD goes low, we have
implemented a HPD snoop mode on the DP159RGZEVM. This mode allows the HPD line to be routed
around the DP159, but remain connected to the DP159 on the sink side to allow the DP159 to snoop its
state. This snoop mode is disabled by default on the DP159RGZEVMs.
• Pop R131, no pop R129, R130, R139 for HPD on
• No pop R131, pop R129, R130, R139 for HPD snoop only
2.5.2 DDC Snoop Option – not Available for DP159RGZ REV B
To accommodate systems that do not properly support clock stretching on the DDC lines, we have
implemented a snoop mode on the DP159RGZEVM. This mode allows the DDC lines to be routed around
the DP159RGZ, but remain connected to the DP159RGZ on the sink side to allow the DP159RGZ to
snoop the DDC traffic. This snoop mode is enabled by default on the DP159RGZ REV B1 EVMs.
• Pop R126, R125, R132, R133. No pop R31, R32 – DP159RGZ, DDC snoop only
• Pop R31, R32. No pop R126, R125, R132, R133 – DP159RGZ, DDC on

2.6 Local I2C Access Through J5
Access to DP159’s local I2C signals is provided via the J5 input connector. Note that I2C signal levels
should be at 3.3 V when I2C interface is accessed through the connector.
A standalone external I2C host can be connected via J5 for debug and control purposes. An example of an
external I2C Host controller is the Total Phase Aardvark I2C/SPI Host Adapter (Total Phase Part#:
TP240141). Sample scripts for this I2C Host controller are provided by request.

2.7 Local I2C Access Through USB Interface via TUSB3410
Access to DP159’s local I2C signals is also provided through the TUSB3410 on the DP159RGZEVM using
a USB TI Utility called Eye Scan. To use the utility:
• Install the Eye Scan software from Texas Instruments
• J6 must be set to SDA – SDA_USB
• J4 must be set to SCL – SCL_USB
• Attach USB micro cable to J13 and to the host computer
NOTE: The USB connection should be made prior to installing any DP or HDMI cables.
• Start the Eye Scan software

2.8 Rsadj Potentiometer
The default Rsadj value on the DP159RGZEVM is 7.0 kΩ. The optimal value for an application may vary
from 4.7 kΩto 7 kΩ. To allow customers to test the effects of various Rsadj values, there is a
potentiometer on the EVM at R76. The Rsadj value can be varied by turning the knob and setting J8 to
[2,3].
3 Quick Start Guide
The following steps provide quick start instructions:
1. Connect USB cable from J13 to a USB host, set SW2 to 3. LED D2 should light up.
Option: Apply 5-V power to J9, set SW2 to 1. LED D2 should light up.
2. If using external I2C adapter instead of pin straps, configure the DP159 at this step using J5 or through
the USB interface.
3. Plug in a DP source using a standard DP cable into J2 (Standard DP connector).
4. Plug in an HDMI video sink device into P2 (standard HDMI connector) using a standard HDMI cable.
5. Video output on HDMI sink should be observed.
