RS-485 Passive Equalization Reference Design

TIDA-00790

Design files

Overview

This reference design allows for evaluation of special transmission line termination networks to compensate for high frequency cable losses. Using this technique helps to achieve better jitter performance for bidirectional point to point connections.

Features
  • Works with any TI RS-485 tranceiver
  • Better jitter performance
  • Higher data rates across long cables
  • Low cost due to use of passive components

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