Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 74HC4046ADB,118 is a multi-functional device used in communication systems and data processing equipment. It is mainly used as a clock input or feedback signal phase locked loop (PLL) frequency synthesizer, which is made up of a phase detector, a voltage controlled oscillator (VCO), and a filter designed to vary the frequency of an oscillator according to the phase of an input reference signal.

The 74HC4046ADB,118 is well suited for both clock generation and frequency synthesizing applications. In a clock generation application, the device uses a crystal controlled oscillator to generate various frequencies. This oscillator can be used for various synchronizing circuits such as a clock divider and multiplexer. The reference signal input range is from 50 Hz to 200 kHz. The device is also capable of generating frequencies from 10 kHz to 60 MHz.

In a frequency synthesizer application, the 74HC4046ADB,118 uses a phase detector to compare the reference signal with the VCO signal. The output of the phase detector driving a voltage-controlled filter, controls the filter frequency, thus, causing the VCO frequency to be adjusted to match with the reference signal frequency.

The 74HC4046ADB,118 can be used in a variety of different applications such as time-keeping systems, clock dividers, pulse-width modulation (PWM) signal generators, or PCM code converters, as well as in communication systems, including multiplexers, collision avoidance systems, and security system signal processors. It is also useful in mobile communications, computer networks, and navigation systems.

The 74HC4046ADB,118 is designed to provide excellent noise immunity, low-power consumption, and high speed operation, providing a versatile solution for clock generation and frequency synthesis applications. It is widely used in industrial, automotive, military, and space environments.
