High Speed Transmission with LVDS Link Devices
High speed data transmission requires a designer to be aware of factors which may impact the correct sampling of data. In particular, items such as excessive skew and jitter can lead to data sampling errors, limiting the maximum bandwidth performance of the LVDS Link. The following is a discussion of LVDS Link receiver data sampling, skew and jitter margin, and an explanation of skew and jitter components. LVDS LINK DATA SAMPLING The advantage of using the LVDS Link devices (FPD Link and Channel Link) is the ability to convert many parallel data lines into a narrower serialized interface. This serialized LVDS interface is capable of running at seven times the data rate of the parallel TTL interfa
