Description
The ’HC4046A and ’HCT4046A are high-speed silicon-gate
CMOS devices that are pin compatible with the CD4046B of
the “4000B” series. They are specified in compliance with
JEDEC standard number 7.
The ’HC4046A and ’HCT4046A are phase-locked-loop
circuits that contain 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 signal input can be directly coupled to large voltage
signals, or indirectly coupled (with a series capacitor) to small
voltage signals. A self-bias input circuit keeps small voltage
signals within the linear region of the input amplifiers. With a
passive low-pass filter, the 4046A forms a second-order loop
PLL. The excellent VCO linearity is achieved by the use of
linear op-amp techniques.
