我们的任意频率、任意输出格式Si5360、Si5391、Si5341、Si5340时钟石英振荡器将宽带PLL与专有的多同步小数合成技术相结合，提供多功能、超低抖动时钟发生器平台。凭借高度灵活的架构，时钟发生器能够在多达18路差分时钟输出上合成高达1300 MHz的各种整数和非整数相关频率组合，同时提供55 fs RMS相位抖动性能，0 ppm误差。

The Si5360 clock generator for high-speed networking, data center and communications equipment complements Skyworks’ current market leading Si5391/5341/5332 line of clock generators delivering higher levels of jitter performance with a greater number of clock outputs.

The Si5360 clock generator combines Skyworks’ 5^th generation DSPLL™ and MultiSynth™ technologies with an ultra-low jitter VCO to deliver outstanding 55 fs RMS phase jitter reference clocks for high-performance applications like 112G/224G PAM-4 SerDes and Coherent Optics that are used in 400G/600G/800G/1.2Tb Ethernet communications and data center equipment.

The Si5360 is used in applications that demand the highest level of integration and jitter performance. All PLL components are integrated on-chip, reducing the risk of noise coupling associated with discrete solutions and greatly simplifying the clock solution design.

The Si5360 architecture has a one DSPLL with 2 MultiSynths enabling the capability of generating combinations of clock output frequencies that are integer- and non-integer related.
