Crystal Oscillator

Si540 Data Sheet

Ultra Low Jitter Any-Frequency XO (125 fs), 0.2 to 1500 MHz

KEY FEATURES

The Si540 Ultra Series

™

oscillator utilizes Silicon Laboratories’ advanced 4

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 Si540

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

3.2×5 mm and 5×7 mm footprints, the Si540 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 Si540 uses one simple crystal and a DSPLL IC-based

approach to provide the desired output frequency. This process also guarantees

100% electrical testing of every device. The Si540 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.
