November 22, 2022 | I-Connect007 Editorial TeamEstimated reading time: 1 minute
Understanding and controlling sources of differential-pair skew is critical to signal integrity and reduces the potential for nightmarish field failures.
Differing micro-environments can cause slight signal delays within a differential pair, leading to apparently random field failures in production. This is known as glass weave skew, a phenomenon that's easier to prevent that predict.
A serial link’s differential-skew budget shrinks as bit rates increase. For example, a 1 Gbps (500 MHz) signal would have roughly 250 ps of skew tolerance. That’s a wide window, and why most engineers didn’t need to worry about GWS 20+ years ago.
In this November 30, 2022 webinar we explore eleven possible solutions to help prevent glass-weave skew, with an eye toward manufacturing costs and future-proofing your designs.
The webinar covers
- Deterministic methods for addressing GWS
- Probabilistic GWS mitigation methods
- Glass styles and their relative suitability for mitigating GWS
