DESCRIPTION
FEATURES
SY87701AL
s Industrial temperature range (–40
°C to +85°C)
s 3.3V power supply
s Clock and data recovery from 28Mbps up to 1.3Gbps
NRZ data stream, clock generation from 28Mbps to
1.3Gbps
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 Lower power: fully compatible with Micrel's
SY87701V, but with 30% less power
s Available in 32-pin EPAD-TQFP and 28-pin SOIC
packages (28-pin SOIC is available, but NOT
recommended for new designs.)
The SY87701AL is a complete Clock Recovery and
Data Retiming integrated circuit for data rates from
28Mbps up to 1.3Gbps 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 SY87701AL also includes a link fault detection
circuit.
