XO/VCXO Part Number Selector

Silicon Labs provides a web-based utility to simplify configuration. The utility validates and generates part numbers for single, dual, quad and any-rate frequency devices. Simply run the web utility to automatically submit your part number request for qualification by Silicon Labs.

Buy Now

Run the XO/VCXO part number selector to order samples or production quantities of any Si5xx XO/VCXO. Samples ship in two weeks and production orders typically ship in four weeks. Click here to run the web-based XO/VCXO Part Number Selector.

Unmatched Performance

The Si5xx 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

Utilizing Silicon Labs’ DSPLL technology, the Si5xx 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.

Industry’s Shortest Lead Times

Silicon Labs changes the manufacturing model enabling the shortest and most predictable lead times for high-frequency, low-jitter oscillators. By moving the frequency control and tuning into a mixed-signal IC, complex manufacturing steps are either eliminated or simplified.
