DESCRIPTION
FEATURES
s 3.3V and 5V power supply options
s Clock and data recovery from 32Mbps up to
1.25Gbps NRZ data stream, clock generation from
32Mbps to 1.25Gbps
s Complies with Bellcore, ITU/CCITT and ANSI
specifications for applications such as OC-1, OC-3,
OC-12, ATM, FDDI, Fibre Channel and Gigabit
Ethernet, as well as proprietary applications
s Two on-chip PLLs: one for clock generation and
another for clock recovery
s Selectable reference frequencies
s Differential PECL high-speed serial I/O
s Line receiver input: no external buffering needed
s Link fault indication
s 100K ECL compatible I/O
s Available in 32-pin EPAD-TQFP and 28-pin SOIC
packages (28-pin SOIC is available, but not
recommended for new designs, see page 2 for
details
The SY87701V 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 SY87701V also includes a link fault detection
circuit.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
APPLICATIONS
s SONET/SDH/ATM OC-1, OC-3, OC-12, OC-24
