RRing_1
I
Receive Ring Input - Channel 1:
This input pin along with RTIP_1 is used to receive the bipolar line signal from
the Remote DS3/E3 Terminal.
35
AVDD_1
****
Receive Analog VDD - Channel 1
36
RLB_1
I
Remote Loop-back - Channel 1:
This input pin along with LLB_1 dictates the Loop-Back mode in which Chan-
nel 1 in the XRT73L02 is operating.
A "High" on this pin with LLB_1 being set to “Low" configures Channel 1 of the
XRT73L02 to operate in the Remote Loop-back Mode.
A "High" on this pin with LLB_1 also being set to "High" configures Channel 1
of the XRT73L02 to operate in the Digital Local Loop-back Mode.
N
OTE
:
This input pin is ignored and should be connected to GND if the
XRT73L02 is operating in the HOST Mode.
37
LLB_1
I
Local Loop-back - Channel 1:
This input pin along with RLB_1 dictates the Loop-Back mode in which Chan-
nel 1 in the XRT73L02 is operating.
A "High" on this pin with RLB_1 set to "Low" configures Channel 1 of the
XRT73L02 to operate in the Analog Local Loop-back Mode.
A "High" on this pin with RLB_1 set to "High" configures Channel 1 of the
XRT73L02 to operate in the Digital Local Loop-back Mode.
N
OTE
:
This input pin is ignored and should be connected to GND if the
XRT73L02 is operating in the HOST Mode.
38
LOSTHR_1
I
Loss of Signal Threshold Control - Channel 1:
The voltage forced on this pin controls the input loss of signal threshold for
Channel 1. Forcing the LOSTHR_1 pin to GND or VDD provides two settings.
This pin must be set to the desired level upon power up and should not be
changed during operation.
N
OTE
:
This pin is only applicable during DS3 or STS-1 operations.
39
E3_Ch_1
I
E3 Select Input - Channel 1:
A "High" on this pin configures Channel 1 of the XRT73L02 to operate in the
E3 Mode.
A "Low" on this pin configures Channel 1 of the XRT73L02 to check the state
of the STS-1/DS3_Ch_1 input pin
N
OTE
:
This input pin is ignored and should be connected to GND if the
XRT73L02 is operating in the HOST Mode.
40
SR/DR
I
Receive Output Single-Rail/Dual-Rail Select:
Setting this pin "High" configures the Receive Sections of all Channels to out-
put data in a Single-Rail Mode to the Terminal Equipment.
Setting this pin "Low" configures the Receive Section of all Channels to output
data in a Dual-Rail Mode to the Terminal Equipment.
41
STS-1/DS3_Ch_1
I
STS-1/DS3 Select Input - Channel 1:
Set this pin to “High” for STS-1 and “Low” for DS3 Operation.
The XRT73L02 ignores this pin if the E3_Ch_1 pin is set to “1". This input pin
is ignored if the XRT73L02 is operating in the HOST Mode. If the XRT73L02
is operating in the HOST Mode, the pin should be tied to GND.
