7.3.6.3.1 Code Group Synchronization (CGS)

The first step in initializing the JESD204B link, after SYSREF is processed, is to achieve code group synchronization. The receiver first asserts the SYNC signal when ready to initialize the link. The transmitter responds to the request by sending a stream of K28.5 characters. The receiver then aligns its character clock to the K28.5 character sequence. Code group synchronization is achieved after receiving four K28.5 characters successfully. The receiver deasserts SYNC on the next local multiframe clock (LMFC) edge after CGS is achieved and waits for the transmitter to start the initial lane alignment sequence.
