CTCLK
Input M3
Common Transmit Clock (CTCLK). This input signal
is used as a reference transmit tributary clock which
can be used in egress Clock Master: Clear Channel
mode. Depending on the configuration of the TEMAP,
CTCLK may be a line rate clock (so the transmit clock
is generated directly from CTCLK, or from CTCLK after
jitter attenuation) or a multiple of 8kHz (Nx8khz, where
1?N?256) so long as CTCLK is jitter-free when divided
down to 8kHz (in which case the transmit clock is
derived by the DJAT PLL using CTCLK as a
reference).
The TEMAP may be configured to ignore the CTCLK
input and utilize one of the recovered Ingress clocks
instead, RECVCLK1 and RECVCLK2. Receive
tributary clock[x] is automatically substituted for CTCLK
if line loopback is enabled.
