Description
1
PDC
Peak Detector Capacitor.
This pin should be connected to a 0.1
F capacitor.
2
RXDATA-
I
Receive Analog Input Positive.
Line analog input.
3
RXDATA+
I
Receive Analog Input Negative.
Line analog input.
4
TE
O
Tank Excitation Output.
This output connects to one side of the tank circuitry.
5
BIAS
O
Bias.
This output is to be connected to the center tap of the receive transformer.
6
TANK BIAS
O
Tank Bias.
The tank circuitry is biased via this output.
7
RGND
Receiver Ground.
To minimize ground interference a separate pin is used to ground the
receive section.
8
RCLK
O
Recovered Receive Clock.
Recovered clock signal to the terminal equipment.
9
RVCC
Receive Supply Voltage.
5V supply voltage to the receive section.
10
RNEG
O
Receive Negative Data.
Negative pulse data output to the terminal equipment (active low).
11
RPOS
O
Receive Positive Data.
Positive pulse data output to the terminal equipment (active low).
12
TNEG
I
Transmit Negative Data.
TNEG is valid while TCLK is high.
13
TXDATA+
O
Transmit Positive Output.
Transmit bipolar signal is driven to the line via a transformer.
14
TGND
Transmit Ground.
15
TXDATA-
O
Transmit Negative Output.
Transmit bipolar signal is driven to the line via a transformer.
16
TCLK
I
Transmit Clock.
Timing element for TPOS and TNEG.
17
TPOS
I
Transmit Positive Data.
TPOS is valid while TCLK is high.
18
TVCC
Transmit Supply Voltage.
5V supply voltage to the transmit section.
