Sts-12/sts-3 Multi Rate Clock And Data Recovery Unit

The VSC8115 functions as a Clock and Data Recovery unit for SONET SDH-based equipment to derive high speed Timing signals. The VSC8115 recovers the Clock from the scrambled NRZ data operating at 622.08Mb/s (STS-12/OC-12/STM-4) or 155.52Mb/s (STS-3/OC-3/STM-1). After the Clock is recovered, the data is retimed using an output Flip-Flop Both recovered Clock and retimed data outputs CAN be configured as LVDs or LVPECL signals to facilitate a low-jitter and low power Interface By Vitesse Semiconductor Corp
