Overview

UNISONIC TECHNOLOGIES CO.
, LTD U74HC4046A PHASE LOCKED LOOP WITH VCO CMOS IC  DESCRIPTION The U74HC4046A is a phase-locked-loop circuit including a linear voltage-controlled oscillator (VCO), three different phase comparators (PC1, PC2 and PC3), a common signal input amplifier and a common SOP-16 comparator input.
The signal can be directly coupled to large voltage signals or with a series capacitor coupled to small voltage signals.
Small voltage signals can be kept within the linear region of the input amplifiers with a self-bias input circuit.
The U74HC4046A and a passive low-pass filter form a second-order loop PLL.
With a linear op-amp, the VCO achieves excellent linearity.
