SY69754AL
3.3V, 622Mbps Clock
and Data Recovery
General Description
The SY69754AL is a complete Clock Recovery and
Data Retiming integrated circuit for OC-12/STS-12
applications at 622Mbps 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 SY69754AL also includes a link fault detection
circuit.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.

Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Airflow of 500lfpm recommended for 28-pin SOIC.
4. Using JEDEC standard test boards with die attach pad soldered to PCB. See www.amkor.com for additional package details.
