Design files

Overview

This reference design demonstrates how the 56G PAM-4 retimer DS560DF410 can be used to equalize high-speed signals in active electical cable applications. The design is a module compliance board (MCB) which routes signals from a QSFP-DD connector through a retimer to SMA and MXP connectors in both ingress and egress directions.

Features
  • 8 independent channels for each direction
  • QSFP-DD cable compatibility, for both ingress and egress
  • Host-side Huber-Suhner and SMA compatibility, for both ingress and egress
  • Configurable through electrically erasable programmable read-only memory (EEPROM) or USB-to-I2C communication
  • Headers for all relevant debug and configuration pin controls and interrupts
  • Onboard power regulation for 3.3 V → {1.8 V, 1.2 V} domains
