VDD: 5-volt supply, 5%.
Ground: 0 volts reference.
AGC VDD: Isolate from VDD using 1N914 or 1N4148
diode.
AGC Ground: 0 volts reference.
Data In 1: HDB3 or B8ZS encoded bipolar receive
data input.
Data In 2: DC Voltage Reference for Data Input DI1.
The MRT uses an internally generated voltage refer-
ence as an AC ground for the received data input. An
external 0.1 F capacitor, in parallel with a 10 F/6.3 V
tantalum capacitor, is connected between this pin and
ground. No other connection should be made to this
pin.
Transmit Negative Out: Line transmit negative; out-
put is an active low.
Transmit Positive Out: Line transmit positive; output
is an active low.
Receive Negative: When PNENB is low, the HDB3
codec is bypassed and N-rail (RN) data is provided on
this pin. When PNENB is high, the output is forced to
a high impedance state.
Receive Positive/Receive Data: When PNENB is
low, the HDB3 codec is bypassed and P-Rail (RP)
data is provided on this pin. When PNENB is high,
NRZ data (RD) is provided.
Clock Out Inverted: Receive inverted clock output.
Positive and negative rail receive data is clocked out
on the rising edge. Disabled in the NRZ mode.
