Spur-Free, 50 MHz - 2.1 GHz Single Fractional-N Frequency Synthesizer: SKY72310-11

Source: Skyworks Solutions, Inc.

The SKY72310-11 is a fractional-N frequency synthesizer designed to provide ultra-fine frequency resolution, fast switching speed, and low phase-noise performance for high-performance radio system designs that require low power and fine step size. The ultra-fine step size of less than 100 Hz allows this synthesizer to be used in very narrowband wireless applications.

The SKY72310-11 synthesizer’s fine step size can compensate for crystal oscillator or intermediate frequency (IF) filter drift. As a result, crystal oscillators or crystals can replace temperature-compensated or ovenized crystal oscillators, reducing parts count and associated component cost. The device’s fine step size can also be used for Doppler shift corrections.
