SDI Video Aggregation Reference Design

Overview

TopologyBoost Converter
Input voltage3.3-5 V

Description

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.

Features

  • 1:8 clock distributior synchonizes source inputs with the aggregator

  • Combines four 720p HD-SDI video sources into a single serial link for transmission over a single differential pair or optical fiber

  • Recovery, de-aggregation and seamless display of the original video content at remote nodes located hundreds of meters away

  • Schematic, layout, test data and design documentation are provided for ease of reuse

  • Adaptive equalization and transmit de-emphasis integrated into both low-speed and high-speed side to reduce jitter and increase transmission distance
