SILICON LABS 598BCA001687DG

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 trillion (PPT) resolution. The device is programmed via a 2-pin I²C 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.
