7.4 G.703 Synchronization Signal
The DS21348 can receive a 2.048MHz square-wave synchronization clock as specified in Section 13 of
ITU G.703(10/98). To use the DS21348 in this mode, set the Receive Synchronization Clock Enable
(CCR5.3) = 1. The DS21348 can also transmit the 2.048MHz square-wave synchronization clock as
specified in Section 10 of G.703. To transmit the 2.048MHz clock, set the Transmit Synchronization
Clock Enable (CCR5.2) = 1.
