TX Control
The TX circuit performs the following functions:
generate TxCEN to enable the HDLC transmitter.
handle Transmit Packet Termination.
allow RX and TX Handshaking
merge D-Channel data from the HDLC controller into the local TDM stream.
These functions will be described in the sections below.
13.3.1
The HDLC transmitter is controlled by the MT90812 generated Transmit Clock Enable signal, TxCEN. The
TxCEN output signal enables the HDLC transmitter in the appropriate channel as specified by the system, via
