OReceive Clock Output - Channel (n):
This output pin is the Recovered Clock signal from the incoming line sig-
nal for Channel (n). The Receive Section of Channel (n) outputs data via
the RPOS_(n) and RNEG_(n) output pins on the rising edge of this clock
signal.
Configure the Receive Section of Channel (n) to update the data on the
RPOS_(n) and RNEG_(n) output pins on the falling edge of RxClk_(n)
by doing one of the following:
a. Operating in the Hardware Mode
Pull the RxClkINV pin to "High".
b. Operating in the HOST Mode
Write a "1" into the RxClkINV bit-field within the Command Register.

Receive Negative Data Output - Channel (n):
This output pin pulses "High" whenever Channel (n) of the XRT73LC03A
has received a Negative Polarity pulse in the incoming line signal at the
RTIP_(n)/RRing_(n) inputs.
NOTE: If the Channel (n) B3ZS/HDB3 Decoder is enabled, then the zero
suppression patterns in the incoming line signal (such as: "00V", "000V",
"B0V", "B00V") is not reflected at this output.

Receive Positive Data Output - Channel (n):
This output pin pulses “High" whenever Channel (n) of the XRT73LC03A
has received a Positive Polarity pulse in the incoming line signal at the
RTIP_(n)/RRing_(n) inputs.
NOTE: If the Channel (n) B3ZS/HDB3 Decoder is enabled, then the zero
suppression patterns in the incoming line signal (such as: "00V", "000V",
"B0V", "B00V") is not reflected at this output.

Receive Ring Input - Channel (n):
This input pin along with RTIP_(n) is used to receive the bipolar line sig-
nal from the Remote DS3/E3/STS-1 Terminal.

Receive Equalization Enable Input - Channel (n):
Setting this input pin "High" enables the Internal Receive Equalizer
within Channel (n). Setting this pin "Low" disables the Internal Receive
Equalizer. The guidelines for enabling and disabling the Receive Equal-
izer are described in Section 3.2.
NOTE: This pin is ignored and should be tied to GND if the XRT73LC03A
is going to be operating in the HOST Mode, (internally pulled-down).
