The Gen-Z Consortium has released a suite of nine final specifications that enables designers to begin the development of products utilizing Gen-Z technology solutions. Our latest white paper takes a deeper dive into the Gen-Z Physical Layer Specification.
To maximize system design flexibility, the Gen-Z Physical Layer Specification does not normatively specify channel frequency masks. Instead, it specifies informative insertion and return loss masks, providing designers with a starting point.
Application-specific use models require different specifications, including memory storage. The white paper presents a case for high-resilience fabric performance while avoiding Forward Error Correction (FEC). The performance is achieved by limiting channel loss in contrast to full allowable interconnect reach.
The new white paper also outlines Channel Operating Margin (COM) and Bit Error Ratio (BER) and how they impact channel topologies and performance. COM is an industry adopted method for validating channel compliance, and is a single measure of the channel performance encompassing signal distortion analysis and methods to compensate for it. BER is a ratio of number of bits received in error, excluding additional bit errors resulting from Decision Feedback Equalizer (DFE) error propagation and the total number of bits transmitted.
