Crystal oscillators offer lowest jitter performance

Silicon Labs has introduced the Si54x family of high-performance crystal oscillators (XOs), said to provide low jitter performance down to 80fs for integer and fractional frequencies across the entire operating range.

“These XOs provide much greater frequency flexibility and excellent jitter margin for demanding applications, including 100G/200G/400G line cards and optical modules, hyperscale data centres, wireless infrastructure and military/aerospace,” said James Wilson, senior marketing director for timing products.

Available with single, dual and quad frequency options in an industry-standard 3.2 x 5mm package, the Si54x offers drop-in compatibility with traditional XOs and supports all popular output formats, including LVDS, LVPECL, HCSL, CML, CMOS and dual CMOS. Devices can be factory-programmed to any frequency in the range from 200kHz to 1.5GHz.
