The CD74HCT4046AM96E4 is a popular integrated circuit (IC) designed and manufactured by Texas Instruments. It is a highly complex, low-cost and low-power clock generator with multiple functions, most notably frequency synthesis and phase-locked loop (PLL) frequency multiplication.

The IC is suitable for a wide variety of applications in development and design, ranging from large-scale computing systems to intelligent controllers, cellular phones and other embedded devices. The operating temperature range for this IC is between -40°C and +85°C, making it suitable for a range of different applications. Additionally, it can operate from a power supply voltage as low as 3.15V.

The core of this clock synthesizer is a low-phase-noise oscillator in the form of a Phase Locked Loop (PLL). This PLL is the basis for the clock generation, which is used to generate output frequencies in the range of 0.51 to 22MHz. The clock generator can also be configured to generate more complex waveforms such as sinusoidal waves and square waves, making it suitable for a variety of different applications.

The CD74HCT4046AM96E4 consists of two main components, an oscillator and an additional logic circuitry. The oscillator is responsible for generating the main clock signal and its frequency is determined by setting the external capacitors on the IC. The logic circuitry, on the other hand, is responsible for generating additional clock signals, based on the main signal feedback. This allows for frequency multiplication and/or frequency division, allowing for more versatile clock generation.

The IC integrates two Multiplexed Bus Interfaces that can be used to establish communications with other devices, such as an external control processor, using an I2C protocol. The logic circuitry of the CD74HCT4046AM96E4 can be configured to operate in two different modes, either in passive or active mode. In passive mode, the externally supplied frequency is adopted, while in active mode the clock frequency is generated internally, by the PLL.

Additionally, the CD74HCT4046AM96E4 also integrates a programmable pulse width modulation (PWM) output. This PWM output can be used to generate a variety of different waveforms for various applications, such as controlling the speed of a motor or the brightness of a LED. The frequency, duty cycle and amplitude of the PWM output can be controlled via control pins on the IC.

The CD74HCT4046AM96E4 is suitable for a variety of different applications such as high-speed clock generators, low frequency clocks and frequency synthesis. It is also suitable for applications where complex waveforms are required, such as PWM and pulse-width phase modulation.

This IC is well-suited for embedded devices such as wireless communication devices and smart home systems, and is designed to consume minimal power while providing high-speed clock signals and frequency synthesis. Its wide operating temperature range and low power supply make it highly reliable and suitable for applications in aerospace and automotive industries.
