6.7 Payload Clock Output
The TCLKO and RCLK pins can output a clock with the F-Bit (T1) or the TS0 and TS16 (E1) bit
position gapped out. This function is only available in T1 or E1 mode. This is useful in basic transceiver
applications where a payload or “demand” clock is needed. In Hardware Mode, the payload clock output
is selected by the L0, L1, and L2 line build-out pins. In Hardware Mode, this function is only available in
certain build-out modes. See the line build-out tables in Section
for selecting the payload clock mode.
