SY69753AL
3.3V, 125Mbps, 155Mbps Clock
and Data Recovery
General Description
The SY69753AL is a complete Clock Recovery and
Data Retiming integrated circuit for OC-3/STS-3
applications at 155Mbps 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 SY69753AL also includes a link fault detection
circuit.
