Si542 Data Sheet

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

MHz

The Si542 Ultra Series

™

oscillator utilizes Silicon Laboratories’ advanced 4

gen-

eration 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

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 operat-

ing range. The Si542 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 indus-

try-standard 3.2x5 mm and 5x7 mm footprints, the Si542 has a dramatically simpli-

fied 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 re-

quired for each output frequency, the Si542 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 Si542 is factory-configura-

ble 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 oscilla-

tors.
