Silicon Labs has introduced a new family of high-performance crystal oscillators (XOs) offering the industry’s lowest jitter frequency-flexible solution. The Si54x Ultra Series XOs deliver ultra-low jitter performance down to 80 femtoseconds (fs) for both integer and fractional frequencies across the entire operating range. They provide frequency flexibility and excellent jitter margin for demanding applications including 100G/200G/400G line cards and optical modules, hyperscale data centres, broadband, wireless infrastructure, broadcast video, industrial, test and measurement, and military/aerospace.
Si54x Ultra Series XOs are available with single, dual and quad frequency options in an industry-standard 3,2 x 5 mm package, enabling simple, drop-in compatibility with traditional XOs. They support all popular output formats including LVDS, LVPECL, HCSL, CML, CMOS and Dual CMOS.
The oscillators use Silicon Labs’ fourth-generation DSPLL technology to provide an ultra-low-jitter clock source at any output frequency. The device is factory-programmed to any frequency from 200 kHz to 1,5 GHz with < 1 ppb resolution. This enables the company to ship samples of any frequency XO in 1-2 weeks and production quantities in four weeks.
