Philsar PS2500
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 narrowband wireless applications.| Part No. | PS2500 |

DESCRIPTION
With proper temperature sensing or through control channels, the synthesizer’s fine step size can compensate for crystal oscillator or 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.
