PIN DESCRIPTION (CONT'D)
Pin#
Symbol
Type
Description
95
TTIP1
O
Transmitter 1 Positive Bipolar Output.
Channel 1 within the XRT5997 device will use this pin, along with TRing1, to
transmit a bipolar line signal, via a 1:2 step-up transformer.
96
TGND1
Digital Ground.
Transmitters 1.
97
TxClk1
I
Transmitter Clock Input – Channel 1:
If the user operates Channel 1 (within the XRT5997 device) in the “clocked”
mode, then the “Transmit Section” of the Channel 1 will use the falling edge of
this signal to sample the data at the TxPOS1 and TxNEG1 input pins.
Note:
If the user operates the Channel 1 in the “clockless” mode, then the
Terminal Equipment should not apply a clock signal to this input pin..
98
TxNEG1
I
Transmitter - Negative Data Input – Channel 1:
The exact signal that should be applied to this input pin depends upon
whether the user intends to operate the “Transmit Section” (of the Channel 1)
in the “Clocked” or “Clockless” Mode.
Clocked Mode:
The Terminal Equipment should apply bit-wide NRZ pulses on this input pin,
whenever the Terminal Equipment needs to transmit a “negative-polarity”
pulse onto the line via TTIP1 and TRing1 output pins. The XRT5997
device will sample this input pin upon the falling edge of the TClk1 signal.
Clockless Mode:
The Terminal Equipment should apply RZ pulses to this input pin, anytime the
Terminal Equipment needs to transmit a “negative-polarity” pulse onto the
line via TTIP1 and TRing1 output pins.
99
TxPOS1
I
Transmitter - Positive Data Input – Channel 1:
The exact signal that should be applied to this input pin depends upon
whether the user intends to operate the “Transmit Section” (of Channel 1) in
the “Clocked” or “Clockless” Mode.
Clocked Mode:
The Terminal Equipment should apply bit-wide NRZ pulses on this input pin,
whenever the Terminal Equipment needs to transmit a “positive-polarity”
pulse onto the line via TTIP1 and TRing1 output pins. The XRT5997
device will sample this input pin upon the falling edge of the TClk1 signal.
Clockless Mode:
The Terminal Equipment should apply RZ pulses to this input pin, anytime the
Terminal Equipment needs to transmit a “positive-polarity” pulse onto the line
via TTIP1 and TRing1 output pins.
100
LOS1
O
Receiver 1 Loss of Signal:
This output pin toggles “high” if Channel 1, within the XRT5997 device has
detected a “Loss of Signal” condition in the incoming line signal.
