Transmit Channel Clock Output Signal (TxCHCLKn):
The exact function of this pin depends on whether or not the trans-
mit framer enables the transmit fractional/signaling interface to
input fractional data, as described below.
If transmit fractional/signaling interface is disabled:
This pin indicates the boundary of each time slot of an outbound
DS1/E1 frame. In T1 mode, each of these output pins is a 192kHz
clock which pulses "High" during the LSB of each 24 time slots. In
E1 mode, each of these output pins is a 256kHz clock which
pulses "High" during the LSB of each 32 time slots. The Terminal
Equipment can use this clock signal to sample the TxCHN0
through TxCHN4 time slot identifier pins to determine which time
slot is being processed.
If transmit fractional/signaling interface is enabled:
TxCHCLKn is the fractional interface clock which either outputs a
clock signal for the time slot that has been configured to input frac-
tional data, or outputs an enable signal for the fractional time slot
so that fractional data can be clocked into the device using the
TxSERCLK pin.

:
Transmit fractional interface can be enabled by
programming to bit 4 - TxFr1544/TxFr2048 bit from
register 0xn120 to ‘1’.
