Low Power Phase-Locked Loop with VCO

The 74HC/HCT4046A are phase-locked loop (PLL) with linear voltage-controlled oscillator (VCO) CMOS device having pins suited to 4046 in a 4000B series. These devices comply to JEDEC standard no. 7A.

A PLL For Perfect Pitch

When Hackaday runs a contest, we see all manner of clever projects. But inevitably there are some we don’t see, because their builders didn’t manage to get them finished in time. [Park Frazer]’s phase ...

Figure 2. Die micrograph of the proposed digital phase locked loop (PLL) (IMAGE)

The total power consumption of the proposed PLL is only 8.89 mW from a 1 V supply, which leads to a figure of merit of reference of -247.4 dB. Credit must be given to the creator. Only noncommercial ...
