RCLKO
Output
Recovered PCM Clock Output
(RCLKO). This output signal is the
recovered 2.048 MHz clock,
synchronized to the XCLK signal. The
RCLKO signal is recovered from the
received analog inputs (if the interface
is powered up), from the RDP and
RDN inputs (if the input format is dual-
rail RZ), or from the RCLKI input (if
the input format is NRZ).
RDPCM/
Output
37
42
Recovered Decoded PCM (RDPCM).
This output is available when the
E1XC is configured for decoded data
output. This NRZ output signal is the
recovered data stream with HDB3
decoding applied, if HDB3 decoding is
enabled. It is updated on the falling
edge of RCLKO. The RDPCM signal
is not meant to be used when the
digital receive interface is configured
for unipolar operation (RUNI = 1 and
RDIEN = 1), since the data should be
available at the RDD input.
RPCM
Recovered PCM (RPCM). This output
is available when the E1XC is
configured for raw data output. This
NRZ output signal is the recovered
data stream without optional HDB3
decoding applied. It is updated on the
falling edge of RCLKO.
