Description

JESD204B links are the latest trend in data-converter digital interfaces. These links take advantage of high-speed serial-digital technology to offer many compelling benefits including improved channel densities. This reference design addresses one of the challenges of adopting the new interface: understanding and designing the link latency. An example achieves deterministic latency and determines the link latency of a system containing the Texas Instruments LM97937 ADC and Xilinx Kintex 7 FPGA.

Features
  • Guarantee deterministic latency across the JESD204B link
  • Understand the tradeoff between link latency and tolerance to link delay variation
  • Use a formulaic and procedure-based approach to design the link latency
  • Implement a JESD204B link using Texas Instruments' ADC16DX370 or LM97937 ADC and a Xilinx Kintex 7 FPGA
