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 […]

OMRON Corporation of Kyoto, western Japan globally released its new MOS FET (*1) relay module “G3VM-21MT” on December 2, 2019. The product is the first electronic component in the world (2) to adopt a “T-type circuit structure” (3). With a T-type circuit structure consisting of compact-size and longer-lifecycle solid-state relays that output signals using no physical contact, the relay
The purpose of a PLL is to generate a frequency and phase-locked output oscillation signal. To accomplish this objective, past methods primarily worked by adjusting the PLL output frequency often based on the phase error (i.e. the faster/slower phase relationship) to produce a temporary, non-constant frequency and phase-locked output oscillation signal. The constant fluctuation in

Back in the 486 days, it was common to see a “Turbo” button on the front panel of many PCs, which was used to toggle between the CPU’s maximum speed and a slower clock rate that was sometimes necessary for compatibility with older software. Usually an LED would light up to show you were running
