VSC8115YA-05-T

General Description
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.
