| 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 |
