M28331/M28332/M28333 (–3x)
Resynchronized receive data intended to be
strobed out by the corresponding RCLK.
When ENDECDIS = 1, these outputs are
positive and negative AMI data (RPOS and
RNEG).
When ENDECDIS = 0, these outputs are
decoded NRZ data (RNRZ) and line code
violation (RLCV). A line code violation is
indicated when RLCV = 1.
See notes on the ENDECDIS pin in the
Control Signals section.
Recovered clock for each channel receiver,
intended for strobing the corresponding
RDAT into the following framer or logic.
