TIDA-00136

Design files

Overview

The TIDA-00136 reference design is a high speed serial video interface to connect a remote automotive WVGA TFT LCD display with OpenLDI (LVDS) Interface to a video processing system. It uses TIs FPD-Link II SerDes technology to transmit uncompressed video data over shielded twisted pair or Coax cable. Application examples are rear seat entertainment systems, automotive clusters, and Head Unit Display. This design incorporates the DS99R421Q1-EVK and DS90UR124-Q1 boards together to create the solution.

Features
  • Support WVGA x 60 Hz data rates
  • Direct Connect to Displays supporting the OpenLDI Standard (LVDS)
  • Built In Self-Test (BIST) ASIL B Applications
  • AEC-Q100 Serialilzer and Deserializer
