Applications

• SONET/SDH systems

• +3.3 V power supply

• 20-pin TSSOP package

The VSC8115 functions as a Clock and Data Recovery (CDR) unit for

SONET/SDH-based equipment to derive high-speed timing signals. The

VSC8115 recovers the clock from the scrambled NRZ data operating

at 622.08 Mbps (STS-12/OC-12/STM-4) or 155.52 Mbps (STS-3/OC

3/STM-1). After the clock is recovered, the data is retimed using an

output fl ip-fl op. 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.
