Si545

Ultra Series™ Crystal Oscillator Si545 Data Sheet Ultra Low Jitter Any-Frequency XO (80 fs), 0.2 to 1500 MHz The Si545 Ultra Series™ oscillator utilizes Silicon Laboratories’ advanced 4th generation DSPLL® technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is factory-programmed to any frequency from 0.2 to 1500 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequencies across its operating range. The Si545 offers excellent reliability and frequency stability as well as guaranteed aging performance. On-chip power supply filtering provides industry-leading power supply noise rejection, simplifying the task of generating low jitter clocks in noisy systems that use switchedmode power supplies. Offered in a small, industry-standard 3.2×5 mm footprint, the Si545 has a dramatically simplified supply chain that enables Silicon Labs to ship custom frequency samples 1-2 weeks after recei...
