MRing_2
I
Monitor Ring Input - Channel (n):
The bipolar line output signal from TRing_(n) can be connected to this
pin via a 270-ohm resistor in order to check for line driver failure. This
pin is internally pulled "High".

MTIP_0
MTIP_1
MTIP_2
I
Monitor Tip Input - Channel (n):
The bipolar line output signal from TTIP_(n) can be connected to this pin
via a 270-ohm resistor in order to check for line driver failure. This pin is
internally pulled "High".

DMO_0
DMO_1

O
Drive Monitor Output - Channel (n):
If no transmitted AMI signal is present on MTIP_(n) and MRing_(n) input
pins for 128±32 TxClk periods, then DMO_(n) toggles and remains
"High" until the next AMI signal is detected.

TAOS_0
TAOS_1
TAOS_2
I
Transmit All Ones Select - Channel (n):
A "High" on this pin causes the Transmit Section, within Channel (n), to
generate and transmit a continuous AMI all “1’s" pattern onto the line.
The frequency of this "1’s" pattern is determined by TxClk_(n).
This input pin is ignored if the XRT73LC03A is operating in the HOST
Mode.
NOTE: This pin should be tied to GND if the XRT73LC03A is going to be
operating in the HOST Mode, (internally pulled-down).

RLOS_0
RLOS_1
RLOS_2
O
Receive Loss of Signal Output Indicator - Channel (n):
This output pin toggles "High" if Channel (n) has detected a Loss of Sig-
nal Condition in the incoming line signal.
The criteria that the XRT73LC03A uses to declare an LOS Condition
depends upon whether the device is operating in the E3 or STS-1/DS3
Mode.

RLOL_0
RLOL_1
RLOL_2
O
Receive Loss of Lock Output Indicator - Channel (n):
This output pin toggles "High" if Channel (n) has detected a Loss of Lock
Condition. Channel (n) 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%.

LCV_0
LCV_1
LCV_2
O
Line Code Violation Indicator - Channel 0:
Whenever the Receive Section of Channel (n) detects a Line Code Vio-
lation, it pulses this output pin "High". This output pin remains "Low" at
all other times.
NOTE: The XRT73LC03A outputs an NRZ pulse via this output pin. It is
advisable to sample this output pin via the RxClk_(n) clock output signal.

ICT
I
In-Circuit Test Input:
Setting this pin "Low" causes all digital and analog outputs to go into a
high-impedance state to allow for in-circuit testing. This pin should be
set to "High" for normal operation.
This pin is internally pulled "High".
67

LOSTHR_0
LOSTHR_1
LOSTHR_2
I
Loss of Signal Threshold Control - Channel (n):
Forcing the LOSTHR_(n) pin to GND or VDD provides two settings. This
pin must be set to a “High” or “Low” level upon power up and should not
be changed during operation.
This pin is only applicable during DS3 or STS-1 operations.
