How is this calculated?
Protocol capability of Samtec connectors results from a comparison of the protocol channel data rate and the Samtec Channel Performance Metric (CPM) per product. The Samtec CPM estimates connector performance in a pre-defined channel as illustrated below.
This channel-based approach factors impairments—such as the crosstalk and reflections—inherent in real-world signal channels. Samtec CPM sums all channel noise sources and then determines the resultant signal to noise ratio in a specific mated connector pair. By its very nature, CPM is a function of channel assumptions made and will vary from application to application. Achieving similar results requires good SI design practice in the system PCB(s) and using Samtec-provided connector breakout regions (BOR).
The HQCD series has a CPM of 14 Gbps NRZ.
HQCD products are capable of protocols whose channel data rates are less than this CPM.
For more information, please read this blog article: A New High Speed Connector Rating That Accounts For The Entire System and download the Samtec Channel Performance Metric white paper.
Samtec recommends contacting [email protected] for technical support prior to final connector selection in any specific high-speed application.
