If I put a SN7490(divided by five) IC in a Frequency Synthesizer PLL
cirucit. Is it equal to input frequency * 5?

If you put it between the output of the VCO and the
VCO output frequency will be 5 times the frequency
on the external input to the phase comparator, on
average. The output of the divider will be 1/5 of the
VCO output and will equal the external input.
