PRODUCTION DATA.
In the CGS state, the device transmits a set of /K28.5/ characters that are used by the receiver to recover the clock and data from the serial stream using a clock and data recovery (CDR) circuit, and also to align to the symbol boundaries. The device enters the CGS state when it receives an active (low going) SYNC pulse that is at least four device clocks wide. In addition, when the device is in the CGS state as defined by the JESD204B standard, the device can also be made to transmit a stream of /K28.5/ symbols by programming the TX_SYNC_REQ register control.
