PRODUCTION DATA
The link layer serves multiple purposes in JESD204C for both 8B/10B and 64B/66B encoding schemes, however there are some differences in implementation for each encoding scheme. In general, the link layer's responsibilities include scrambling of the data (see Scrambler), establishing the code (8B/10B) or block (64B/66B) boundaries and the multiframe (8B/10B) or multiblock (64B/66B) boundaries, initializing the link, encoding the data, and monitoring the health of the link. This section is split into an 8B/10B section (8B/10B Link Layer) and a 64B/66B section (64B/66B Link Layer) in order to cover the specific implementation for each encoding scheme.
