TIDA-00424

Design files

Overview

A video clock sub-system designed to perform video sync separation and derives synchronous video clocks for video and audio sub-systems.

Features
  • Sync separation from incoming video signal
  • Precision clock generation synchronous to the incoming video signal
  • Multiple PLL's to generate video clocks at 27MHz, 148.5MHz, 148.35MHz, and audio clock at 24.576MHz
  • Clock distribution with output drivers
  • Self-contained video clock sub-system
  • Proven design with demo board, design files and GUI
