XF - Pin Assignment - 2.5 x 2.0 mm
Description
The XF is a quartz-based PLL clock oscillator family with <150fs phase jitter offered in three package options: 2.5mm x 2.0mm, 3.2mm x 2.5mm, and 5.0mm x 3.2mm packages. It is ideal for enterprise-level equipment that demands low noise, stable, and accurate timing/clock sources. The XF is a quartz-based PLL oscillator with a key focus on noise reduction technologies. Typical phase jitter is 120fs over 12kHz to 20MHz bandwidth. The XF devices are available in a wide frequency range from 15MHz to 2100MHz.
Short lead-time, low noise, wide frequency range, excellent ambient performance, and very little engineering effort to incorporate this into your design makes the XF series an excellent choice over the conventional technologies. The XF family has stabilities as tight as ±25ppm for -40 °C to +85 °C and ± 50ppm for -40 °C to +105 °C. This XF family provides extremely quick delivery for both standard and custom frequencies.
This device is factory-configurable.

- Application NotePDF 1.53 MB R31AN0034EU0102 Rev.1.02 Oct 21, 2025AI-generated Summary: PLL loop filter design involves selecting component values to ensure stable operation and optimized phase noise. The loop bandwidth depends on parameters like charge pump current, VCO gain, and feedback divider. Second and third order passive loop filters are common, with specific calculations for cutoff, zero, and pole frequencies guiding component selection. Proper tuning of loop bandwidth enhances PLL stability and phase noise performance, demonstrated through lab experiments and calculation examples.
