CD4046B Phase-Locked Loop: A Versatile Building Block for Micropower Digital and Analog Applications:Introduction:
Phase-locked loops (PLLs), especially in monolithic form, have significantly increased use in signal-processing and digital systems. Frequency modulation (FM) demodulation, frequency shift keying (FSK) demodulation, tone decoding, frequency multiplication, signal conditioning, clock synchronization, and frequency synthesis are some of the many applications of a PLL. The PLL described in this application report is the CD4046B, which consumes only 600 ?W of power at 10 kHz, a reduction in power consumption of 160 times when compared to the 100 mW required by similar monolithic bipolar PLLs. This power reduction has particular significance for portable battery-operated equipment. This application report discusses the basic fundamentals of PLLs, and presents a detailed technical description of the CD4046B, as well as some of its applications.
