VSC8115
Overview
155/622 Mbps (OC-3/12/STM-1/4) Clock and Data Recovery
The VSC8115 functions as a Clock and Data Recovery (CDR) unit for SONET/SDH-based equipment to derive highspeed 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 flipflop. In the absence of a invalid signal, the PLL will lock to the reference clock, providing the downstream device a constant clock signal, and reducing the relocking time.
