DESCRIPTION

FEATURES

■ Low voltage, 3.3V power supply operation

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

a30kHztrianglemodulationwith0.5%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).

■ 200MHz precision LVPECL output from a low cost

16.66MHz crystal

■ 0.5% spread-spectrum modulation control

■ > 7dB reduction in EMI with spread-spectrum

modulation

■ LVTTL/LVCMOS compatible control inputs

■ interfaces directly to a crystal

■ Precision PLL architecture ensures < 30ps

peak-to-peak, cycle-to-cycle output jitter

■ 48%-to-52% precision duty cycle is ideal for double-

data-rate clocking applications

■ Available in low cost 32-pin TQFP and 28-pin SOIC

APPLICATIONS

packages

■ High-speed synchronous systems

■ CPU clock

■ Multi-processor workstations and servers

■ Networking
