Receive Positive Analog Input (RTIPn):
RTIP is the positive differential input from the line interface. This
input pin, along with the RRING input pin, functions as the “Receive
DS1/E1 Line Signal” input for the XRT86VL32 device.
The user is expected to connect this signal and the RRING input
signal to a 1:1 transformer for proper operation. The center tap of
the receive transformer should have a bypass capacitor of 0.1
μ
F to
ground (Chip Side) to improve long haul application receive capa-
bilities.

Receive Negative Analog Input (RRINGn):
RRING is the negative differential input from the line interface. This
input pin, along with the RTIP input pin, functions as the “Receive
DS1/E1 Line Signal” input for the XRT86VL32 device.
The user is expected to connect this signal and the RTIP input sig-
nal to a 1:1 transformer for proper operation. The center tap of the

Receive Loss of Signal Output Indicator (RLOSn):
The XRT86VL32 device will assert this output pin (i.e., toggle it
“high”) anytime (and for the duration that) the Receive DS1/E1
Framer or LIU block declares the LOS defect condition.
Conversely, the XRT86VL32 device will tri-state this output pin any-
time (and for the duration that) the Receive DS1/E1 Framer or LIU
block is NOT declaring the LOS defect condition.

1.
This output pin will toggle "high" (to denote that LOS is
being declared) whenever either the Receive DS1/E1
Framer or the Receive DS1/E1 LIU block (associated with
Channel N) declares the LOS defect condition. In other
words, the state of this output pin is a logic OR of the
Framer LOS and the LIU LOS condition.
2.
Since the XRT86VL32 device tri-states this output pin
(anytime the channel is NOT declaring the LOS defect
condition). Therefore, the user MUST connect a "pull-
down" resistor (ranging from 1K to 10K) to each RxLOS
output pin, in order to pull this output pin to the logic
"LOW" condition, whenever the Channel is NOT declaring
the LOS defect condition.
