Receive Positive Analog Input (RTIPn):
RTIP is the positive differential input from the line inter-
face. This input pin, along with the RRING input pin, func-
tions as the “Receive DS1/E1 Line Signal” input for the
XRT86VL38 device.
The user is expected to connect this signal and the
RRING input signal to a 1:1 transformer for proper opera-
tion. 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 capabilities.

Receive Loss of Signal Output Indicator (RLOSn):
The XRT86VL38 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 XRT86VL38 device will negate this output
pin (i.e., toggle it “l(fā)ow”) anytime (and for the duration that)
the Receive DS1/E1 Framer or LIU block is NOT declaring
the LOS defect condition.
This output pin will toggle “High” (declare LOS) if the
Receive Framer or the Receive LIU block associated with
Channel N determines that an RLOS condition occurs. In
other words, this pin is OR-ed with the LIU RLOS and the
Framer RLOS bit. If either the LIU RLOS or the Framer
RLOS bit associated with channel N pulses high, the cor-
responding RLOS pin of that particular channel will be set
to “High”.
