Skyworks Solutions Inc. Si598/Si599 I2C Crystal Oscillators
Skyworks Solutions Inc. Si598 and Si599 I2C Crystal Oscillators (XOs) and Voltage-Controlled Crystal Oscillators (VCXOs) provide a single output clock at any frequency up to 525 MHz. These crystal oscillators feature excellent tuning resolution (28 parts per trillion) and simplify clock generation in applications that require low jitter clock synthesis. The flexibility of the Skyworks Solutions Inc. Si598 and Si599 enables a single component to replace multiple discrete oscillators and crystal-based clock generators, reducing component count and cost. These I2C XOs and VCXOs leverage the proven Skyworks Solutions Inc. low jitter DSPLL architecture to minimize design time and risk. The Si598 and Si599 XOs and VCXOs are the industry's most highly integrated solution for low-jitter clock synthesis, reducing PCB footprint, simplifying the supply chain, and enabling design re-use.Features
