Overview: Ultra Series™ Crystal Oscillator (VCXO) Si565 Data Sheet Ultra Low Jitter Any-Frequency VCXO (100 fs), 0.2 to 3000 MHz
The Si565 Ultra Series™ voltage-controlled crystal oscillator utilizes Skyworks Solutions’ 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 3000 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequencies across its operating range. 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 switched-mode power supplies. Offered in industry-standard footprints, the Si565 has a dramatically simplified supply chain that enables Silicon Labs to ship custom frequency samples 1-2 weeks after receipt of order. Unlike a traditional XO, where a different crystal is required for each output frequency, the Si565 uses one simple crystal and a DSPLL IC-based approach to provide the desired output frequency. The Si565 is factory-configurable for a wide variety of user specifications, including frequency, output format, and OE pin location/polarity. Specific configurations are factory-programmed at time of shipment, eliminating the long lead times associated with custom oscillators.
