DESCRIPTION
FEATURES
SY87701L
■ Industrial temperature range (–40°C to +85°C)
■ 3.3V power supply
■ Clock and data recovery from 32Mbps up to
1.25Gbps NRZ data stream, clock generation from
32Mbps to 1.25Gbps
■ 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
■ Two on-chip PLLs: one for clock generation and
another for clock recovery
■ Selectable reference frequencies
■ Differential PECL high-speed serial I/O
■ Line receiver input: no external buffering needed
■ Link fault indication
■ 100k ECL compatible I/O
■ Available in 32-pin EPAD-TQFP and 28-pin SOIC
packages (28-pin SOIC is available, but NOT
recommended for new designs.)
The SY87701L 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 SY87701L also includes a link fault detection
circuit.
All support documentation can be found on Micrel’s web
site at www.micrel.com.
