The transmitter block, which interfaces to DAC devices, takes one of more digital sample streams and converts them into one or more serial streams.
The transmitter performs the following functions:
- Data scrambling
- Frame or lane alignment
- Character generation
- Serial lane monitoring
- 8B/10B encoding
- Data serializer
- TX CSR—manages the configuration and status registers.
- TX_CTL—manages the SYNC_N signal, state machine that controls the data link layer states, LMFC, and also the deterministic latency throughout the link.
- TX Scrambler and Data Link Layer—takes in 32 bits of data that implements the Initial Lane Alignment Sequence (ILAS), performs scrambling, lane insertion and frame alignment of characters.
