The SY87701L is a complete Clock Recovery and Data
Retiming integrated circuit for data rates from 32Mbps
up to 1.25Gbps NRZ. The device is ideally suited for
SONET/SDH/ATM and Fibre Channel applications and
other high-speed data transmission systems.
Clock recovery and data retiming is performed by
synchronizing the on-chip VCO directly to the incoming
data stream. The VCO center frequency is controlled by
the reference clock frequency and the selected divide
ratio. On-chip clock generation is performed through the
use of a frequency multiplier PLL with a byte rate source
as reference.
The SY87701L also includes a link fault detection
circuit.
