DATA SHEET
- 20 of 96 -
Receive Line Clock for Channel n: The 44.736 or
34.368 Mbit/s line signals on the RPOSn/RNEGn signal
leads are clocked out on falling edges of this clock when
control bit INVCO (bit 4 in XC1H) is set to 0 for the corre-
sponding channel. These signals are clocked out on ris-
ing edges when control bit INVCO is set to 1.
This lead is forced to a high impedance state when
Transmit Line Positive Rail/NRZ Data: for Channel n.
When control bit DECODE (bit 7 in XC1H) is set to 0 for
the corresponding channel, this lead is used as the NRZ
input for the 44.736 (DS3) or 34.368 Mbit/s (E3) asyn-
chronous line signal. When control bit DECODE is a 1,
the corresponding lead provides the positive rail data
input for the internal decoder.
Transmit Negative Rail Data or LOS Input: When con-
trol bit DECODE (bit 7 in XC1H) is a 1, the corresponding
lead provides the negative rail data input for the internal
decoder. When control bit DECODE is set to 0 for the
corresponding channel, this lead can be used to input an
external loss of signal alarm. If a lead is not used, it must
be tied to ground.
Transmit Line Clock: The NRZ or rail signal for a corre-
sponding channel is clocked in on rising edges of this
clock when control bit INVCI (bit 5 in XC1H) is set to 0.
NRZ or rail data is clocked in on falling edges when con-
trol bit INVCI is set to 1.
Monitor Transmit Line Data: Output provided for an
optional external performance monitoring circuit. This
serial NRZ output is provided after the line decoder in the
transmit direction, and is independent of whether the
transmit line input is configured for a NRZ or rail inter-
face. Data is clocked out on rising edges of clock
(RnNRC). This lead is forced to a high impedance state
