FEATURES  
DESCRIPTION  
■ Industrial temperature range (–40°C to +85°C)  
■ 3.3V power supply  
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.  
■ 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  
The SY87700L also includes a link fault detection  
circuit.  
All support documentation can be found on Micrel’s web  
site at: www.micrel.com.  
■ 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  
APPLICATIONS  
■ Available in 32-pin EPAD-TQFP and 28-pin SOIC  
packages (28-pin SOIC is available, but is not  
recommended for new designs.)  
■ SONET/SDH/ATM OC-1 and OC-3  
■ Fast Ethernet, SMPTE 259  
■ Proprietary architecture up to 175Mbps
