General Description
The SY87700AL is a complete clock recovery and data
retiming integrated circuit for data rates from 32Mbps up
to 208Mbps NRZ. The device is ideally suited for
SONET/SDH/ATM 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 SY87700AL also includes a link fault detection
circuit.
