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
μ
F capacitor, in parallel with a 10
μ
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

O
TTL4mA
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.
RP/RD
13
O
TTL4mA
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.
CLKO

O
CMOS8mA
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.
