MorganStandard Linear & LogicABSTRACTA pplications of the CD4046B Phase-Locked loop device, such as FM demodulation, FSKdemodulation, tone decoding, frequency multiplication, signal conditioning, clocksynchronization, and frequency synthesis, are discussed. The monolithic-formlow-power-consumption CD4046B particularly is desirable for use in portablebattery-powered .. 2 Review of PLL Fundamentals3.
the voltage on the capacitor of the LPF constant. Moreover, the signal at the phase-pulses output is at a high level, and can be used for indicating a locked condition. Thus, for phase comparator II, no phase difference exists between signal and comparator input over the …
