TxClk_1
I
Transmit Clock Input for TPData and TNData - Channel 1:
This input pin must be driven at 34.368 MHz for E3 applications, 44.736 MHz
for DS3 applications or 51.84 MHz for SONET STS-1 applications. The
XRT73L02 uses this signal to sample the TPData_1 and TNData_1 input pins.
By default, the XRT73L02 is configured to sample these two pins on the falling
edge of this signal.
If operating in the HOST Mode, the XRT73L02 can be configured to sample
the TPData_1 and TNData_1 input pins on either the rising or falling edge of
TxClk_1.
63
TPData_1
I
Transmit Positive Data Input - Channel 1:
The XRT73L02 samples this pin on the falling edge of TxClk_1. If it samples a
"1", then it generates and transmits a positive polarity pulse to the line.
N
OTES
:
1. The data should be applied to this input pin if the Transmit Section is
configured to accept Single-Rail data from the Terminal Equipment.
2. If operating in the HOST Mode, the XRT73L02 can be configured to
sample the TPData_1 pin on either the rising or falling edge of
TxClk_1.
64
TNData_1
I
Transmit Negative Data Input - Channel 1:
The XRT73L02 samples this pin on the falling edge of TxClk_1. If it samples a
"1", then it generates and transmits a negative polarity pulse to the line.
N
OTES
:
1. This input pin is ignored and tied to GND if the Transmit Section is
configured to accept Single-Rail data from the Terminal Equipment.
2. If operating in the HOST Mode, the XRT73L02 can be configured to
sample the TNData_1 pin on either the rising or falling edge of
TxClk_1.
65
MTIP_1
I
Monitor Tip Input - Channel 1:
The bipolar line output signal from TTIP_1 is connected to this pin via a 270-
ohm resistor to check for line driver failure. This pin is internally pulled "High".
66
MRing_1
I
Monitor Ring Input - Channel 1:
The bipolar line output signal from TRing_1 is connected to this pin via a 270-
ohm resistor to check for line driver failure. This pin is internally pulled "High".
67
AVDD_1
****
Transmit Analog VDD - Channel 1:
68
TTIP_1
O
Transmit TTIP Output - Channel 1:
The XRT73L02 uses this pin with TRing_1 to transmit a bipolar line signal via
a 1:1 transformer.
69
TRing_1
O
Transmit Ring Output - Channel 1:
The XRT73L02 uses this pin with TTIP_1 to transmit a bipolar line signal via a
1:1 transformer.
70
AGND_1
****
Transmit Analog GND - Channel 1
71
AGND_0
****
Transmit Analog GND - Channel 0
72
TRing_0
O
Transmit Ring Output - Channel 0:
The XRT73L02 uses this pin with TTIP_0 to transmit a bipolar line signal via a
1:1 transformer.
