XRT91L33A STS-12/STS-3 Multirate Clock and Data Recovery Unit
The XRT91L33A 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.
技术特性
- Performs clock and data recovery for selectable data of 622.08 Mbps (STS-12/STM-4) or 155.52 Mbps (STS-3/STM-1) NRZ data
- Meets Telcordia, ANSI and ITU-T G.783 and G.825 SDH jitter requirements including T1.105.03 - 2002 SONET Jitter Tolerance specification, and GR-253 CORE, GR-253 ILR SONET Jitter specifications
- Lock output pin monitors data run length and frequency drift from reference clock
