1.3 DS90UH928QEVM Overview

The DS90UH928Q deserializer supports rich audiovisual applications in automotive navigation and rear seat entertainment systems. The DS90UH928Q 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
  • Internal Pattern Generation
  • Loop-through monitor outputs for observing link integrity
