A SerDes Balancing Act: Co-Optimizing TX and RX Equalization Settings to Maximize Margin
Increasing complexity in SerDes Tx and Rx designs requires trading off Tx and Rx equalization to maximize receiver eye margin. This involves trading off ISI and amplitude while choosing what equalization to apply at the Tx and Rx. This webinar presents co-optimization results for various channel types: lossy, ISI-dominated, industry-reference and hypothetical. Results presented are based on SiSoft's OptimEye technology, which makes advanced Co-Optimization accessible to anyone working with serial links.
Attendees will learn:
- How different types of SerDes equalization affect receiver margin
- How channel characteristics affect equalization strategies
- How to balance Tx and Rx settings to maximize margin
- Methods for automating the balancing process
- System designers working with IBIS-AMI models
- SerDes designers developing IBIS-AMI models
- Managers of groups working with IBIS-AMI models
- Engineers verifying SerDes settings in the lab
