Table 2.  Glossary List
Term Description
Converter Device ADC or DAC converter
Logic Device FPGA or ASIC
Octet A group of 8 bits, serving as input to 64/66 encoder and output from the decoder
Nibble A set of 4 bits which is the base working unit of JESD204C specifications
Block A 66-bit symbol generated by the 64/66 encoding scheme
Link Clock

Link Clock = Lane Line Rate/66.
Frame A set of consecutive octets in which the position of each octet can be identified by reference to a frame alignment signal.
Frame Clock A system clock which runs at the frame's rate, that must be 1x or 2x link clock.
Samples per frame clock

Samples per clock, the total samples in frame clock for the converter device.
LEMC Internal clock used to align the boundary of the extended multiblocks between lanes and into the external references (SYSREF or Subclass 1).
Subclass 0 No support for deterministic latency. Data should be immediately released upon lane to lane deskew on receiver.
Subclass 1 Deterministic latency using SYSREF.
Multipoint Link Inter-device links with 2 or more converter devices.
64B/66B Encoding Line code that maps 64-bit data to 66 bits to form a block. The base level data structure is a block that starts with 2-bit sync header.
FEC Forward error correction
