CD74HCT4046AMG4 Application Field and Working Principle The CD74HCT4046AMG4 is a highly integrated clock generator and phase locked loop (PLL) component manufactured by Texas Instruments, Inc. Its main purpose is to generate a stable clock and provide frequency synthesis capabilities through its integrated PLL component. It is a programmable analog device which offers an exceptionally low power consumption and supports a range of frequencies from two to four hundred megahertz.The CD74HCT4046AMG4 is a CMOS (Complementary Metal Oxide Semiconductor) clock generator and phase locked loop integrated circuit (IC). It contains two integrated programmable items: a phase-locked loop and a low power CMOS oscillator. The phase-locked loop section offers an adjustable frequency division from 1 to 50, as well as adjustable phase delays from 0 to 90 degrees. The IC also has an oscillator with a wide range of output frequencies from 2 to 400MHz. This clock generator and PLL integrated circuit is designed to operate with any common logic device and works even over wide ranges of temperature and power supply variations.The adjustable frequency division and the adjustable phase delays are controlled by the inputs of the IC. In both the frequency division and phase delay modes, the inputs vary the frequency division division ratio or the phase delay time accordingly. When the inputs turn on, the phase shift increases and when the inputs turn off, the phase shift decreases.The phase-locked loop is a circuit which uses feedback to lock a signal to a reference frequency. In the case of the CD74HCT4046AMG4, the reference frequency is generated by a low power CMOS oscillator. The loop, featured on the IC, combines the oscillator with an adjustable frequency division and adjustable phase delays to create an efficient, low power and programmable clock generator.The CD74HCT4046AMG4 is an all-in-one, low power solution for designing frequency synthesizers, PLLs and clock generators. The IC features low input current to reduce circuit power consumption, as well as a wide temperature range specified over which it can operate without changing its program settings.The CD74HCT4046AMG4 is used in a range of applications, including mobile phones, satellite communications systems, digital television receivers, automotive electronics and in industrial automation systems. It is a highly versatile component and can be combined with other digital and analog components to create a tailored and cost-effective solution for a wide variety of applications.In conclusion, the CD74HCT4046AMG4 is an all-in-one clock generator and PLL component manufactured by Texas Instruments, Inc. It offers exceptionally low power consumption, wide temperature range performance and supports a considerable range of frequencies. The component also offers adjustable frequency division and adjustable phase delays, allowing designers to quickly and easily create tailored and cost-effective solutions for a wide variety of applications.
