BRPCM/
Output
Backplane Receive PCM (BRPCM).
The BRPCM signal is available on this
output when the backplane is
configured for single-rail output.
BRPCM contains the recovered data
stream passed through ELST and the
SIGX. When the ELST is not by-
passed, the BRPCM stream is aligned
to the backplane timing and is
updated on the falling edge of
BRCLK. When the ELST is by-
passed, BRPCM is aligned to the
receive line timing and is updated on
the falling edge of RCLKO.
BRDP
Backplane Receive Positive Line
Pulse (BRDP). The BRDP signal is
available on this output when the
backplane is configured for dual-rail
output. The BRDP NRZ output
represents the RZ receive digital
positive pulse signal extracted from
the input bipolar signal. BRDP is
updated on the falling edge of
RCLKO.
