Target Specification
VSC8115
STS-12/STS-3 Multi Rate
Clock and Data Recovery Unit
G52272-0, Rev. 1.1
Features
Performs clock and data recovery for
622.08Mb/s (STS-12/OC-12/STM-4) or
155.52Mb/s (STS-3/OC-3/STM-1) NRZ data
Meets Bellcore, ITU and ANSI Specifications
for Jitter Performance
19.44MHz reference frequency LVTTL Input
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.
