PRODUCTION DATA
The link layer serves multiple purposes in JESD204C for both 8b/10b and 64b/66b encoding modes, however there are some differences in implementation for each encoding scheme. In general, the link layer responsibilities include scrambling of the data (see Scrambler and Descrambler), establishing the code (8b/10b) or block (64b/66b) boundaries and the multiframe (8b/10b) or multiblock (64b/66b) boundaries to deskew the Serdes lanes, initializing the link, encoding the data, and monitoring the health of the link.
