FEATURES
DESCRIPTION
s Low voltage, 3.3V power supply operation
s 200MHz precision LVPECL output from a low cost
16.66MHz crystal
s 0.5% spread-spectrum modulation control
s > 7dB reduction in EMI with spread-spectrum
modulation
s LVTTL/LVCMOS compatible control inputs
s interfaces directly to a crystal
s Precision PLL architecture ensures < 30ps
peak-to-peak, cycle-to-cycle output jitter
s 48%-to-52% precision duty cycle is ideal for double-
data-rate clocking applications
s Available in low cost 32-pin TQFP and 28-pin SOIC
packages
The SY89529L is a high-speed, precision PLL-based
LVPECL clock synthesizer with spread-spectrum
modulation control. With an external 16.66MHz crystal
providing a reference frequency to the internal PLL, the
differential PECL output frequency will be 200MHz with
< 30ps (20ps typ.) peak-to-peak, cycle-to-cycle output
jitter. The SY89529L spread-spectrum mode operates with
a 30kHz triangle modulation with 0.5% down-spread (+0.0%/
–0.5%). When spread-spectrum is activated, the output
signal is modulated which spreads the peak amplitudes
and, thus, decreases EMI (Electro-Magnetic Interference).
APPLICATIONS
s High-speed synchronous systems
s CPU clock
s Multi-processor workstations and servers
s Networking
