PAM4 Electrical: How to Test for the Latest Specifications
The accelerated development of 400G Ethernet technology is driving new requirements through the test community as it relates to measuring electrical PAM4 systems. This presentation will review PAM4 measurement methodologies and expand on emerging needs related to FFE reference equalization, clock recovery challenges, BER measurement needs as well as SNDR as it relates to multi-level signaling. An overview of the recent CEI and IEEE spec revisions will also be included.
Attendees will learn:
- Learn the latest updates to CEI and IEEE specs
- Gain insight on FFE reference equalization needs
- Overcome challenges with clock recovery
- Get an In-depth look at SNDR as it relates to multi-level signaling
