Receive Peak Hold R-C Network (RC[4:1]). The
RC[4:1] analog bidirectional pins must be
connected to an external parallel
resistor/capacitor network to RAVS[4:1]. This
network is necessary to the operation of the
internal peak detector that tracks the incoming
signal level.

Output 89
Receive Digital Data (RDD[4:1]). When
configured for unipolar outputs, the RDD[4:1]
NRZ outputs contain the sampled DS-1 or E1
data which has been decoded by AMI, B8ZS, or
HDB3 line code rules. RDD[4:1] outputs can be
updated on either the falling or rising RCLKO[4:1]
edge.

Output
Output
Receive Digital Positive Pulse (RDP[4:1]). When
configured for bipolar outputs, the RDP[4:1] NRZ
outputs contain sampled bipolar positive pulses.
RDP[4:1] outputs can be updated on either the
falling or rising RCLKO[4:1] edge.
Sliced Positive Line Pulse (SDP[4:1]). A positive
pulse on the SDP[4:1] outputs corresponds to the
sampled positive pulse excursion on the
RXTIP[4:1] input.
