XRT91L33：STS-12/STS-3 Multirate Clock and Data Recovery Unit

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.
