Description

(Top View)

The Si598 XO/Si599 VCXO utilizes Silicon Laboratories' advanced DSPLL®

circuitry to provide a low-jitter clock at any frequency. They are user-

programmable to any output frequency from 10 to 810 MHz with 28 parts per

SDA

V_DD

trillion (PPT) resolution. The device is programmed via a 2-pin I C compatible

serial interface. The wide frequency range and ultra-fine programming resolution

make these devices ideal for applications that require in-circuit dynamic frequency

adjustments or multi-rate operation with non-integer related rates. Using an

integrated crystal, these devices provide stable low jitter frequency synthesis and

replace multiple XOs, clock generators, and DAC controlled VCXOs.
