Serializer Operation Mode (Continued)

A third method of serialization uses a free-running bit clock on the CKSI signal.

This mode is enabled by grounding the CKREF signal and driving the DIRI signal

HIGH.

At power-up, the device is configured to accept a serialization clock from CKSI. If

a CKREF is received, this device enables the CKREF serialization mode. The

device remains in this mode even if CKREF is stopped. To re-enable this mode,

the device must be powered down and powered back up with “logic 0” on CKREF.
