HOST/(HW)I
HOST-Hardware Mode Select:
This input pin is used to enable or disable the Microprocessor Serial
Interface (e.g., consisting of the SDI, SDO, SClk, and CS pins).
Setting this input pin "High" enables the Microprocessor Serial Interface
(e.g. configures the XRT73L04B to operate in the HOST Mode). In this
mode, configure the XRT73L04B via the Microprocessor Serial Interface.
When the XRT73L04B is operating in the HOST Mode, then it ignores
the states of many of the discrete input pins. Setting this input pin "Low"
disables the Microprocessor Serial Interface (e.g., configures the
XRT73L04B to operate in the Hardware Mode). In this mode, many of
the external input control pins are functional. (Internally Pulled-up)

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".

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".

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_3
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 XRT73L04B is operating in the HOST
Mode.
NOTE: This pin should be tied to GND if the XRT73L04B is going to be
operating in the HOST Mode, (internally pulled-down).

RLOS_2
RLOS_3
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 XRT73L04B uses to declare an LOS Condition
depends upon whether the device is operating in the E3 or STS-1/DS3
Mode.

RLOL_0

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%.
