The CD74HC4046AM is a high-speed CMOS logic phase-locked loop (PLL) that integrates a voltage-controlled oscillator (VCO) and three phase comparators. It operates effectively within a frequency range of up to 18 MHz at a supply voltage of 5V, with a minimum center frequency of 12 MHz at 4.5V. The device supports a wide operating temperature range from -55¬8C to 125¬8C and is designed for low power consumption compared to LSTTL logic ICs. This PLL features three types of phase comparators: an exclusive-OR, an edge-triggered JK flip-flop, and an edge-triggered RS flip-flop, allowing flexibility in application. The VCO's frequency linearity is enhanced through linear op-amp techniques, and it includes a VCO-inhibit control for power management. The device is compatible with both standard CMOS and LSTTL logic levels, making it suitable for various applications such as frequency synthesis, FM modulation, and motor-speed control. The CD74HC4046AM is available in a 16-lead SOIC package, making it a compact option for integration into electronic designs.
