The HCF4046B CMOS Micropower Phase-Locked Loop (PLL) consists of a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators having a common signal-input amplifier and a common comparator input.
A 5.
2V zener diode is provided for supply regulation if necessary.
PIN CONNECTION September 2001 1/12 HCF4046B VCO Section The VCO requires one external capacitor C1 and one or two external resistors (R1 or R1 and R2).
Resistor R1 and capacitor C1 determine the frequency range of the VCO and resistor R2 enables the VCO to have a frequency offset if required.
The high input impedance (1012Ω) of the VCO simplifiers the design of low-pass filters by permitting the designer a wide choice of resistor-to-capacitor ratios.
In order not to load the low-pass filter, a source-follower output of the VCO input voltage is provided at termi...
