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 is the evaluation board for the XF family field adjustable oscillator. With RMS phase jitter of less than 150fs over the full 12kHz to 20MHz integration range, the...

The XF and XP family of field-programmable clock oscillators (XOs) are optimized for use data centers, optical and wireline communication network, and industrial level equipment that demands very low noise, stable, and accurate timing/clock sources. These devices are single-output clock oscillators with an integrated resonator that utilizes a proprietary ASIC with a key focus on reduction in phase noise and phase jitter. Typical phase jitter is 120fs over 12kHz to 20MHz bandwidth. These chips are available in a wide frequency range from 15MHz to 2100MHz.
