O
Receive Positive Data Output - Channel 0:
The function of this pin is dependent on the setting of the CS/(SR/DR)
pin.
Receive Positive Data
If CS/(SR/DR) is set “Low” (Dual-Rail Mode), this output pin pulses
"High" whenever Channel 0 has received a Positive Polarity pulse in the
incoming line signal at the RTIP0/RRing0 inputs.
Data Output
If CS/(SR/DR) is set “High” (Single-Rail Mode), data is output on this pin.
N
OTE
:
If the B3ZS/HDB3 Decoder is enabled then the zero suppression
patterns in the incoming line signal (such as: "00V", "000V", "B0V",
"B00V") is not reflected at this output.

RLOS0
O
Receive Loss of Signal Output Indicator - Channel 0:
This output pin toggles "High" if Channel 0 has detected a Loss of Signal
Condition in the incoming line signal.
The criteria that the XRT73L04 uses to declare an LOS Condition
depends upon whether the device is operating in the E3 or STS-1/DS3
Mode.
65
RLOL0
O
Receive Loss of Lock Output Indicator - Channel 0:
This output pin toggles "High" if Channel 0 has detected a Loss of Lock
Condition. Channel 0 declares an LOL (Loss of Lock) Condition if the
recovered clock frequency deviates from the Reference Clock frequency
(available at the EXClk(n) input pin) by more than 0.5%.
66
EXClk0
I
External Reference Clock Input - Channel 0:
Apply a 34.368 MHz clock signal for E3 applications, a 44.736 MHz clock
signal for DS3 applications or a 51.84 MHz clock signal for SONET STS-
1 applications.
The Channel 0 Clock Recovery PLL uses this signal as a Reference Sig-
nal for Declaring and Clearing the Receive Loss of Lock Alarm. The
Clock recovery PLL also generates the exact clock for the LIU.
It is permissible to use the same clock that drives the TxClk(n) input pin.
It is permissible to operate the four Channels at different data rates.
