Overview

This high speed multi-channel data capture reference design enables optimum system performance. System designers needs to consider critical design parameters like clock jitter and skew for high speed multi-channel clock generation, which affects overall system SNR, SFDR, channel to channel skew and deterministic latency. This reference design demonstrates multi-channel AFE and clock solution using high speed data converters with JESD204B, high speed amplifiers, high performance clocks and low noise power solutions to achieve optimum system performance

Features
  • 3.2 Gsps, 1.5 GHz multi- channel high speed analog front for high performance receiver
  • < 5 ps clock skew between channels
  • Multi-channel JESD204B complaint clock solution
  • Scalable platform for pin compatible ADC12DJxx00 family
  • Supports TI’s high-speed converter and capture cards (TSW14J56 / TSW14J57)

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
