Himark FS8170

The FS8170 IC is a serial data input, fully programmable phase-locked loop with a 2.5 GHz prescaler for use in the local oscillator subsystem of radio transceivers. When combined with an external VCO, the FS8170 becomes the core of a very low power frequency synthesizer well-suited for mobile communication applications, such as 2.4 GHz ISM-band wireless data links and cellular GSM and PCS. The FS8170 is also pin compatible with Fujitsu’s MB15E07SL IC.
