Introduction

1.1 DS90UB928QEVM

The Texas Instruments DS90UB928QEVM evaluation module (EVM) helps system designers evaluate the

operation and performance of the DS90UB928Q 5MHz-85MHz FPD-Link III Deserializer (DES). The

device translates a high-speed serialized FPD-Link III interface transported over a single shielded twisted

pair (STP) into four FPD-Link compatible LVDS data output pairs and one LVDS clock.

The DS90UB928QEVM board features a 20-position IDC connector for connecting to the FPD-Link

outputs, and a HSD Automotive Connector for connecting an automotive-grade STP cable to the FPD-Link

III input. The included SMA connectors may also be configured as the FPD-Link III data input, enabling

evaluation of other connectors and cable configurations.

The EVM contains one deserializer device.

1.4 DS90UB928QEVM Overview

The DS90UB928Q deserializer supports rich audiovisual applications in automotive navigation and rear

seat entertainment systems. It receives video data, I2S audio, GPIO, and I2C control over a single

shielded twisted pair cable. The evaluation board and included software enables easy evaluation of the

deserializer features, including:

• Support of 720p video applications with a pixel clock frequency up to 85MHz

• Surround sound I2S Digital Audio Applications with up to 4 I2S data outputs

• Low EMI FPD-Link video output interface

• Bidirectional control channel including GPIO (with 2 dedicated pins), interrupt, and I2C interface

• Up to 10 configurable I2C addresses

• Flexible 3.3V or 1.8V LVCMOS I/O interface

• Adaptive cable equalization

• @SPEED Link BIST Mode and LOCK status indicator LED

• Image Enhancement (White Balancing & Hi-FRC Dithering)

• Backwards compatibility mode allowing pairing with DS90UR905Q and DS90UR907Q serializers
