GENERAL DESCRIPTION
The XRT91L33 is a fully integrated multirate Clock
and Data Recovery (CDR) device for SONET/SDH
622.08 Mbps STS-12/STM-4 or 155.52 Mbps STS-3/
STM-1 applications. The device provides Clock and
Data Recovery (CDR) function by synchronizing its
on-chip Voltage Controlled Oscillator (VCO) to the
incoming serial scrambled non-return to zero (NRZ)
data stream.
Figure 1 shows the block diagram of
the XRT91L33.
