General Description
The SY69753L 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 SY69753L also includes a link fault detection circuit.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
