Crystal Oscillator

Si547 Data Sheet

Ultra Low Jitter Quad Any-Frequency XO (80 fs), 0.2 to 1500

MHz

The Si547 Ultra Series

™

oscillator utilizes Silicon Laboratories’ advanced 4

gener-

ation DSPLL

technology to provide an ultra-low jitter, low phase noise clock at four

selectable frequencies. The device is factory-programmed to provide any four se-

lectable frequencies from 0.2 to 1500 MHz with <1 ppb resolution and maintains ex-

ceptionally low jitter for both integer and fractional frequencies across its operating

range. The Si547 offers excellent reliability and frequency stability as well as guar-

anteed 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

3.2x5 mm and 5x7 mm footprints, the Si547 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 Si547 uses one simple crystal and a DSPLL IC-based ap-

proach to provide the desired output frequencies. This process also guarantees

100% electrical testing of every device. The Si547 is factory-configurable for a wide

variety of user specifications, including frequency, output format, and OE pin loca-

tion/polarity. Specific configurations are factory-programmed at time of shipment,

eliminating the long lead times associated with custom oscillators.
