RDP/
I/O
Receive Digital Positive Line Pulse
(RDP). This input is available when
the E1XC 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 Data (RDD). When
the E1XC 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 E1XC 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.
