General Description

Skyworks SKY72300-362 direct digital modulation fractional-N frequency synthesizer provides ultra-fine frequency resolution, fast switching speed, and low phase-noise performance.

This synthesizer is a key building block 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.
