Receive STS-1/STS-3 Telecom Bus Clock Output –
Channel 0;
The exact function of this input pin depends upon whether the
“STS-1 Telecom Bus Interface associated with Channel 0” is
enabled or not, as described below.
If STS-1 Telecom Bus (Channel 0) has been enabled –
STS-1 Receive Telecom Bus Clock Output – Channel 0;
STS1RXD_CK_0:
All signals, which are output via the “Receive Telecom Bus –
Channel 0” are clocked out upon the rising edge of this clock
signal. This includes the following signals.
• STS1RXD_D_0[7:0]
• STS1RXD_ALARM_0
• STS1RXD_DP_0
• STS1RXD_PL_0
• STS1RXD_C1J1_0
This clock signal will operate at 19.44MHz (For STS-3 mode)
or 6.48MHz (Fro STS-1 mode)
RXVALIDFCS_0 (Receive HDLC block valid FCS Indicator
– Channel 0)
RXGFCCLK_0 (Receive ATM GFC clock signal – Channel
0)
