Receive Digital Positive Line Pulse
(RDP). This input is available when the
T1XC is configured to receive dual-rail
formatted data. The RDP input can be
enabled for either RZ or NRZ waveforms.
When enabled for NRZ, this input may
be enabled to be sampled on the rising
or falling edge of RCLKI. When enabled
for RZ, clock is recovered from the RDP
and RDN inputs.
RDD/
SDP
Receive Digital DS-1 Signal (RDD).
When the T1XC is configured to receive
single-rail data, this input may be enabled
to be sampled on the rising or falling
edge of RCLKI.
Sliced Positive Line Pulse (SDP). This
pin becomes an output when the receive
analog line interface is powered up. A
positive pulse on the SDP output
corresponds to the sampled positive
pulse excursion on the RAS input.
RDN/
I/O
43
45
Receive Digital Negative Line Pulse
(RDN). This input is available when the
T1XC is configured to receive dual-rail
formatted data. The RDN input can be
enabled for either RZ or NRZ waveforms.
When enabled for NRZ, this input may
be enabled to be sampled on the rising
or falling edge of RCLKI. When enabled
for RZ, clock is recovered from the RDP
and RDN inputs.
