SKYWORKS 541FAB001023BAGR

The Si541 Ultra Series oscillator utilizes Skyworks Solutions’ advanced 4th generation DSPLL technology to provide an ultra-low jitter, low phase noise clock at two selectable frequencies. The device is factory-programmed to provide any two selectable frequencies 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 Si541 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 switched-mode power supplies. Offered in industry-standard footprints, the Si541 has a dramatically simplified supply chain that enables Skyworks 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 Si541 uses one simple crystal and a DSPLL IC-based approach to provide the desired output frequencies. This process also guarantees 100% electrical testing of every device. The Si541 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.
