3.2.3.2
Externally generated RxCLK is supplied to both the receiver and transmitter. In addition,
a receive strobe can be connected via CD and a transmit strobe via TxCLK pin. These
strobe signals work on a per bit basis. This operating mode can be used in time division
multiplex applications or for adjusting disparate transmit and receive data rates.
Note: In Extended Transparent Mode, the above mentioned strobe signals provide byte

synchronization (byte alignment).
This means that the strobe signal needs to be detected once only to transmit or
receive a complete byte.

Note: In extended transparent mode the strobe signals need to be detected once only to
transmit or receive a complete byte. Thus byte alignment is provided in this mode.
