Crystal Oscillator

Si545 Data Sheet

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

KEY FEATURES

The Si545 Ultra Series

™

oscillator utilizes Silicon Laboratories’ advanced 4

genera-

tion 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 inte-

ger 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, simplify-

ing 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

Si545 has a dramatically simplified supply chain that enables Silicon Labs to ship cus-

tom frequency samples 1-2 weeks after receipt of order. Unlike a traditional XO,

where a different crystal is required for each output frequency, the Si545 uses one

simple crystal and a DSPLL IC-based approach to provide the desired output frequen-

cy. This process also guarantees 100% electrical testing of every device. The Si545 is

factory-configurable for a wide variety of user specifications, including frequency, out-

put format, and OE pin location/polarity. Specific configurations are factory-program-

med at time of shipment, eliminating the long lead times associated with custom oscil-

lators.
