Receiver
Synchronization State Machine
Two consecutive comma characters without any disparity or code error enables word
synchronization. Four consecutive disparity or code errors enables loss of
synchronization and so disable the word synchronization flag. The word
synchronization flag gates the rate matching FIFO write request. Figure 4–3 shows the
synchronization state machine.

Packet Synchronization
The packet synchronization block looks for the presence of valid TS packets. Valid
packets have either 188 bytes or 204 bytes between synchronization bytes. The
synchronization byte takes the value 0x47 .
The block first looks for the synchronization byte that indicates the start of the packet,
which is indicated by rx_ts_status[1] . The block then counts valid bytes in the
incoming stream. If a synchronization byte is seen 188 or 204 bytes after the first sync
byte is seen, lock is indicated on rx_ts_[5:4] and end of packet is indicated on
rx_ts_status[2] . If no synchronization byte is seen at either 188 or 204 bytes, the
packet is deemed to have an error and rx_ts_status[3] is asserted. The block then
again starts the search for synchronization bytes.
