LLB_0
I
Local Loop-back - Channel 0:
This input pin along with RLB_0 dictates the Loop-Back mode in which Chan-
nel 0 in the XRT73L02 is operating.
A "High" on this pin with RLB_0 set to "Low" configures Channel 0 of the
XRT73L02 to operate in the Analog Local Loop-back Mode.
A "High" on this pin with RLB_0 set to "High" configures Channel 0 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.

RLB_0
I
Remote Loop-back - Channel 0:
This input pin along with LLB_0 dictates the Loop-Back mode in which Chan-
nel 0 in the XRT73L02 is operating.
A "High" on this pin with LLB_0 being set to “Low" configures Channel 0 of the
XRT73L02 to operate in the Remote Loop-back Mode.
A "High" on this pin with LLB_0 also being set to "High" configures Channel 0
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.
26
AVDD_0
****
Receive Analog VDD - Channel 0:
27
RRing_0
I
Receive Ring Input - Channel 0:
This input pin along with RTIP_0 is used to receive the bipolar line signal from
the Remote DS3/E3 Terminal.
28
RTIP_0
I
Receive TIP Input - Channel 0:
This input pin along with RRing_0 is used to receive the bipolar line signal
from the Remote DS3/E3/STS-1 Terminal.
29
AGND_0
****
Receive Analog GND - Channel 0
30
REQEN_0
I
Receive Equalization Enable Input - Channel 0:
Setting this input pin "High" enables the Internal Receive Equalizer of Channel
0. Setting this pin "Low" disables the Internal Receive Equalizer. The guide-
lines for enabling and disabling the Receive Equalizer are described in Section
3.2.
N
OTE
:
This input pin is ignored and should be connected to GND if the
XRT73L02 is operating in the HOST Mode.
31
REQEN_1
I
Receive Equalization Enable Input - Channel 1:
Setting this input pin "High" enables the Internal Receive Equalizer of Channel
1. Setting this pin "Low" disables the Internal Receive Equalizer. The guide-
lines for enabling and disabling the Receive Equalizer are described in Section
3.2.
N
OTE
:
This input pin is ignored and should be connected to GND if the
XRT73L02 is operating in the HOST Mode.
32
AGND_1
****
Receive Analog GND - Channel 1
33
RTIP_1
I
Receive TIP Input - Channel 1:
This input pin along with RRing_1 is used to receive the bipolar line signal
from the Remote DS3/E3/STS-1 Terminal.
