CD74HC4046AE

Product Summary

The CD74HC4046AE is a High-Speed CMOS Logic Phase-Locked Loop with VCO. It is pin compatible with the CD4046B of the “4000B” series. The CD74HC4046AE is specified in compliance with JEDEC standard number 7. The CD74HC4046AE is phase-locked-loop circuit that contains a linear voltage-controlled oscillator (VCO) and three different phase comparators (PC1, PC2 and PC3). A signal input and a comparator input are common to each comparator. The applications of the CD74HC4046AE include FM Modulation and Demodulation, Frequency Synthesis and Multiplication, Frequency Discrimination, Tone Decoding, Data Synchronization and Conditioning, Voltage-to-Frequency Conversion, Motor-Speed Control.
