Having an understanding of the MC74HC4046ADT application field and working principle is an important part of being able to safely, efficiently and effectively design and fabricate clock generator components and circuits. The MC74HC4046ADT is a advanced monolithic timing device which can provide several timer functions which cost-effectively perform a range of clock and timing-related solutions. These solutions range from simple to complex clock management, communication control and synchronous interface solutions.

The MC74HC4046ADT belongs to the MC74HC family, a series of advanced surface mount CMOS logic devices which are CMOS based and offer high speed, with low power and propagation delay. The component belongs to the Clock/Timing subcategory, with the MC74HC4046ADT specifically designed and manufactured for applications which require a general purpose timer, phase-lock loop and voltage-controlled-oscillator.

As an clock generator component, the MC74HC4046ADT can operate up to 4 different frequencies simultaneously, depending on the input voltage. It offers a number of high speed programmable timing elements ranging from 1 Hz up to 122kHz, with a very low power consumption of 20μA maximum. The component is also capable of providing two types of internal compensation, namely frequency compensation and voltage controlled oscillator (VCO) compensation, thereby making it ideal for use in handheld communication control solutions and frequency synthesizers.

In terms of operation, the MC74HC4046ADT uses capacitors and resistors to provide a reference voltage, which is then used to establish the initial high frequency clock. The component then uses a programmable oscillator to shift the clock signal up and down in frequency. By adjusting the voltage at the reference outputs of the component, the frequency band can be adjusted, allowing the frequency to be changed as desired. The component is also capable of automatically tuning itself to the changed frequency, providing a reliable and stable clock signal output.
