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

Skyworks SKY72310 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. With proper temperature sensing or through control channels, the synthesizers 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 devices fine step size CAN also be used for Doppler shift corrections. By Skyworks Solutions, Inc.
