T1/E1/J1 FRAMER/LIU COMBO - ARCHITECTURE DESCRIPTION
1.6
T1/E1 Serial PCM Interface
The most common mode is the standard serial PCM interface. Within this mode, only the serial data, serial
clock, frame pulse and multi-frame pulse are required for both the transmit and receive paths. For the transmit
path, only TxSER is a dedicated input to the device. All other signals to the transmit path in
Figure 7
can be
programmed as either input or output. For the receive path, only RxSER and RxMSYNC are dedicated outputs
from the device. All other signals in the receive path in
Figure 8
can be programmed as either input or output.
