ICS501 simple frequency multiplier

ICS501 simple frequency multiplier

Scott from SWHarden has published a new build:

Today I made a high frequency multiplier using a single component: the ICS501 PLL clock multiplier IC. This chip provides 2x, 5x, 8x (and more) clock multiplication using an internal phased-lock loop (PLL). At less than a dollar on eBay, $1.55 on mouser, and $0.67 on Digikey, they don’t break the bank and I’m glad I have a few in my junk box! I have a 10MHz frequency standard which I want to use to measure some 1Hz (1pps) pulses with higher precision, so my general idea is to use a frequency multiplier circuit to increase the frequency (to 80 MHz) and use this to run a counter IC to measure the number of clock pulses between the PPS pulses.
