Receive Time Slot Octet Identifier Output-Bit 3 (RxCHNn_3)
/ Receive 8KHz Clock Output (Rx8KHZn):
The exact function of these pins depends on whether or not the
receive framer enables the receive fractional/signaling inter-
face, as described below:
If receive fractional/signaling interface is disabled -
RxCHNn_3:
These output pins (RxCHNn_4 through RxCHNn_0) reflect the
five-bit binary value of the current time slot being output by the
receive serial interface. System equipment can use the RxCH-
CLKn to sample the five output pins of each channel to identify
the time slot being output on these pins. RxCHNn_3 indicates
Bit 3 of the time slot channel being output.
If receive fractional/signaling interface is enabled -
Rx8KHZn:
These pins output a reference 8KHz clock signal derived from
the MCLKIN input.

Receive Fractional/Signaling interface can be enabled
by programming to bit 4 - RxFr1544/RxFr2048 bit from
register 0xn122 to ‘1’.

Receive Time Slot Octet Identifier Output-Bit 4 (RxCHNn_4)
/ Receive Recovered Line Clock Output (RxSCLKn):
The exact function of these pins depends on whether or not the
receive framer enables the receive fractional/signaling inter-
face, as described below:
If receive fractional/signaling interface is disabled -
RxCHNn_4:
These output pins (RxCHNn_4 through RxCHNn_0) reflect the
five-bit binary value of the current time slot being output by the
receive serial interface. System equipment can use the RxCH-
CLKn to sample the five output pins of each channel to identify
the time slot being output on these pins. RxCHNn_4 indicates
the Most Significant Bit (MSB) of the time slot channel being
output.
If receive fractional/signaling interface is enabled - Receive
Recovered Line Clock Output (RxSCLKn):
These pins output the recovered T1/E1 line clock (1.544MHz in
T1 mode and 2.048MHz in E1 mode) for each channel.
