DATA SHEET
- 6 of 36 -
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 or RXDIS is low, this pin
is forced to a high impedance state (disabled).
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. When RXDIS is low, this pin is forced
to a high impedance state (disabled).
VDD: V
Digital Ground: 0 volts reference.
AGC VDD: +4.3 volt supply, derived from V
1N914 or 1N4148 diode (see Figure 10).
Analog 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; output
is active high.
Transmit Positive Out: Line transmit positive; output is
active high.
