PS2500 Description
The PS2500 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 in designing high-performance narrowband and multi-band radio systems 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...
