1 Overview
1.1 What is the TDP158?
The TDP158 is a DisplayPort to Transition Minimized Differential Signal (TMDS) redriver supporting Digital
Video Interface (DVI) 1.0 and High Definition Multimedia Interface (HDMI) 1.4b and 2.0 output signals.
The TDP158 supports the Dual Mode Standard version 1.1 type 1 and type 2 through the DDC link. The
TDP158 supports a data rate of up to 6Gbps per data lane to support UltraHD (4K×2K/60Hz) 8-bits per
color high-resolution video and HDTV with 16-bit color depth at 1080p (1920×1080/60Hz).
1.2 What is the TDP158 EVM?
The TDP158 EVM is a PCB created to help customers evaluate the TDP158 device for video applications.
This EVM can also be used as a hardware reference design for implementation of the TDP158 in the RSB
package. PCB design and layout files can be provided upon request to provide PCB design illustrations of
the routing and placement rules. Figure 1 is a picture of the EVM.

1.2.1 What is Included in the TDP158RSBEVM?
The major components of the EVM are as follows:
• TDP158RSB
• Standard DP source connector (receptacle)
• Standard HDMI sink connector (receptacle)
• DC power regulators
• I2C programming interface for external I2C host connection
• USB interface (utility available)
2 Hardware Description
Figure 2 illustrates the EVM block diagram.
Hardware Description
2.1 Video Connectors for TDP158 Ports
The EVM has a DP connection for the source and an HDMI connection for the sink. J2 is a standard DP
connector (Molex 47272-0001). J4 is a standard HDMI connector (Molex 4715-10001). There is a third
video connection on the board for an HDMI source (J1), this function is not supported on the TDP158RSB
EVM.
2.2 Local I2C Access
Access to the local I2C signals on the TDP158 is provided via input connector J18. Note that the I2C signal
levels should be at 3.3 V when the I2C interface is accessed through the connector.
A standalone external I2C host can be connected via J18 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.

NOTE: The target I2C address for the TDP158 can be modified with the EVM jumper settings.
2.3 Enable and Reset
There are three device enable and reset options to use with the EVM.
A. Supervisor circuitry option
This is the default configuration on the TDP158 EVM. 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 is released
high.
B. RC timing option
The C35 external capacitor and internal resistor are used to control the EN ramp time after the device
is powered on. The C35 is a DNI (Do Not Install option) by default. The C35 needs to be installed and
R70 needs to be uninstalled to enable this option.
C. External control option
A push button (SW1) is provided for manual control of the EN and OE input of the TDP158.

2.4 Power
A DC power jack (J13) 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 stated requirements
can be used to power the TDP158RSBEVM. Power is provided to the EVM when SW1 is set to
position 1.
Do 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 to a host and setting SW1 to
position 3. Note that this usage may exceed USB compliance requirements for power consumption.

2.6 Component Population Configuration
To allow the TDP158 EVM to support both HDMI or DP input, there are many components that need to be
removed, placed, or modified depending on the board configuration. Table 4 provides a summary of the
component configuration for the TDP158 RSB. In addition, the unused source receptacle can be
depopulated.

Hardware Description
2.6.1 DDC Snoop Option
To accommodate systems that do not properly resend DDC commands after HPD goes low, TI has
implemented an DDC snoop mode on the TDP158RSB EVM. This mode allows the HPD line to be routed
around the TDP158, but remain connected to the TDP158 on the sink side to allow the TDP158 to snoop
its state. This snoop mode is disabled, by default, on the TDP158RSB EVMs.
• Pop R22, R23, no pop R19, R20, R12, R13 for HDMI, DDC snoop
• Pop R24, R25, no pop R38, R39, R29, R30 for DP, DDC snoop
• Pop R19, R20, R12, R13, no pop R22, R23 for HDMI, DDC on
• Pop R38, R39, R29, R30, no pop R24, R25 for DP, DDC on
2.6.2 HPD Snoop Option
Not available for the TDP158RSB EVM.
2.7 USB Interface via TUSB3410
Use the following settings for USB interface via TUSB3410:
• J19 must be set to SDA – SDA_USB
• J17 must be set to SCL – SCL_USB
• Attached USB micro cable to J16 and to the host computer
• Start the Eye Scan Tool software. Refer to the EyesScan Tool User's Guide (SLUUBK2) for details.
www.ti.com
3 Quick Start Guide
Use the following steps for quick-start procedures:
1. Apply 5-V power to the EVM, turn on SW1. LED D1 should light up.
2. If using external I2C adapter instead of pin straps, configure the TDP158 at this step.
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 J4 (Standard HDMI connector) using a standard HDMI cable.
5. Video output on HDMI sink should be observed.
