General 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.
