The PNP-1090-P22 is a complete low noise frequency synthesizer, comprised of VCO, PLL, loop filter and data interface. The PNP family of RF signal sources is the world’s first truly configurable frequency synthesizer module.
Overview Incorporating the latest Fortemedia technologies for removing ambient noise and acoustic echoes, the FM1288 preserves voice naturalness for greater speech intelligibility in a variety of noisy automotive enviroments. Designed to be compatible with a wide range of host processors and blue-tooth devices, the FM1288 voice processor is designed for easy system integration.
