Product Summary
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. Multi-modulus division ratios of 32/33 and 64/65 are selectable thru serial programming to enable pulse swallowing operation. 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.
