• Manufacturer: Infineon Technologies Corporation

7.4.1.2
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 (HDLC/SDLC), the above mentioned strobe

signals provide byte synchronization (byte alignment).
In ASYNC Mode, the above mentioned strobe signals provide character
synchronization (character alignment).
This means that the strobe signal needs to be detected once only to transmit or
receive a complete byte or character respectively.

Clock Mode 1 Configuration
Note: In extended transparent or ASYNC protocol mode the strobe signals need to be
detected once only to transmit or receive a complete byte or character respectively.
Thus byte/character alignment is provided in these modes.
