TIDA-00352 Reference Design

Texas Instruments

SDI Video Aggregation Reference Design


This verified reference design is a complete four channel SDI aggregation and de-aggregation solution. One TLK10022 is used to aggregate four synchronous HD-SDI sources together into one 5.94 Gbps serial link. The serial data is transferred via copper or optical fiber where a second TLK10022 is used to de-aggregate and seamlessly redisplay the original video content.

  • 1:8 clock distributior synchonizes source inputs with the aggregatorCombines four 720p HD-SDI video sources  into a single serial link for transmission over a single differential pair or optical fiberRecovery: de-aggregation and seamless display of the original video content at remote nodes located hundreds of meters awaySchematic: layout: test data and design documentation are provided for ease of reuseAdaptive equalization and transmit de-emphasis integrated into both low-speed and high-speed side to reduce jitter and increase transmission distance
