Need Samples Fast?

Silicon Labs has partnered with Digi-Key to offer low jitter differential/LVCMOS programmable oscillators with 24-hour lead times. Frequency programming on-site by Digi-Key enables next-day prototypes of standard and custom frequencies, eliminating NRE charges and minimum order quantities required by traditional XO

XO/VCXO Part Number Selector

Silicon Labs provides a web-based utility to simplify the configuration of crystal oscillator devices. The utility allows you to specify a customized crystal oscillator and create a new part number, or if you need to reorder, you can look up an existing product by part number. Samples ship in two weeks and production orders typically ship in four weeks.

Unmatched Performance

The Si5xx crystal oscillator products support frequency ranges from 100 kHz to 1.4 GHz, provide ultra-low jitter performance (<0.3 ps rms typical OC-192) and offer new features previously unavailable in high-frequency oscillators based on SAW resonators or inverted mesa crystals. These features include dual, quad and any frequency operation as well as selectable voltage gain (kV) for VCXO devices.

Highest Reliability

Using Silicon Labs’ DSPLL technology, the Si5xx crystal oscillator products offer total frequency stability over time and temperature that is more than five times better than competing SAW devices. Compared to inverted mesa crystal oscillators, Silicon Labs offers a solution that is more mechanically robust while providing five times better aging stability.
