DESCRIPTION
FEATURES
SY87700L
■
Industrial temperature range (–40
°
C to +85
°
C)
■
3.3V power supply
■
SONET/SDH/ATM compatible
■
Clock and data recovery from 32Mbps up to
175Mbps NRZ data stream, clock generation from
32Mbps to 175Mbps
■
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
■
Complies with Bellcore, ITU/CCITT and ANSI
specifications for applications such as OC-1 and
OC-3 as well as proprietary applications
■
Available in 32-pin EPAD-TQFP and 28-pin SOIC
packages (28-pin SOIC is available, but is not
recommended for new designs.)
The SY87700L is a complete Clock Recovery and Data
Retiming integrated circuit for data rates from 32Mbps
up to 175Mbps 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 SY87700L also includes a link fault detection
circuit.
