12-Gbps Multi-Channel BERT Board Reference Design

TIDA-00426

Design files

Overview

This reference design is a 12-Gbps low-cost bit error tester (BERT) capable of generating and checking up to 8 channels of pseudo-random binary sequences (PRBS). This validated design is a convenient way to generate multi-channels high speed serial bit streams of up to 12-Gbps, and checking incoming serial bit streams for possble bit errors.  This design can be used as a hand-held BERT useful for evaluating the signal integrity and bit error error performance of a high speed sub-system.

Features
  • Eight Pattern Generation Channels
  • Eight Pattern Checking Channels
  • Optional External Reference Clock Inputs
  • Onboard USB-to-I2C for Easy Device Programming
  • Status Display LEDs
