DESCRIPTION

The SY89424V is a low-power Phase Locked Loop (PLL) based frequency synthesizer. The device is capable of generating up to 1GHz clock frequencies with a low-cost 10–25MHz external series-resonant quartz crystal. One can also use PECL differential clock signals to drive this device instead of the quartz crystal.

FEATURES

■ 3.3V and 5V power supply options

■ Up to 1GHz clock frequencies

■ Internal quartz reference oscillator driven by quartz crystal or PECL source

■ Low jitter PLL design

■ On-chip 20 ohm driver

■ Differential outputs with 600mV (min) swing

■ Optional pull-down resistors for AC-coupled outputs

■ Low power consumption

■ External loop filter optimizes performance/cost

■ Available in 16-pin SOIC package
