High Speed CMOS Logic Phase-Locked-Loop With VCO

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.
