All information contained in this datasheet is subject to change without prior notice. HiMARK Technology, Inc. assumes no responsibility for the use of any circuits shown in this datasheet. Description 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. The FS8170 is also pin compatible with Fujitsu’s MB15E07SL IC. Features ! ! ! ! ! ! ! ! !
