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.
In this paper an All Digital phase locked loop is proposed. This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are ...
This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...
