Introduction

1.1 DS90UB927QEVM

The Texas Instruments DS90UB927QEVM evaluation module (EVM) helps system designers evaluate the

operation and performance of the DS90UB927Q 5MHz-85MHz FPD-Link III Serializer (SER). The device

translates four FPD-Link (I) compatible LVDS data input pairs and one LVDS clock into a high-speed

serialized FPD-Link III interface for transport over a single shielded twisted pair (STP) cable.

The DS90UB927QEVM board features a 20-position IDC connector at the FPD-Link input, and a

Rosenberger HSD Automotive Connector at the FPD-Link III output. The included SMA connectors may

also be configured as the FPD-Link III data output, enabling evaluation of other connectors and cable

configurations.

The EVM contains one serializer (SER) device

1.4 DS90UB927QEVM Overview

The DS90UB927Q serializer supports rich audiovisual applications in automotive navigation and rear seat

entertainment systems. It transports LVDS 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

serializer features, including:

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

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

• Low EMI FPD-Link video input 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

• Backwards compatibility mode to DS90UR906Q, DS90UR908Q, and DS90UR916Q

• Low-power modes
