AT-4.000MAHH-T Application Field and Working Principle

The AT-4.000MAHH-T is designed for use in oscillator circuits in a wide variety of devices such as car navigation systems, digital cameras, and audio equipment. In these devices, the oscillator circuit uses the AT-4.000MAHH-T to generate a precise and stable frequency. The oscillator frequency is determined by the AT-4.000MAHH-T’s frequency characteristics, which can be tailored to the application by choosing the appropriate crystal unit.

The oscillator circuit’s central component is the AT-4.000MAHH-T crystal unit. The crystal unit is a temperature-compensated crystal oscillator (TCXO) which contains a quartz crystal vibrating at a precise frequency and a temperature-compensated circuit to adjust the oscillation frequency to meet the desired characteristics. The quartz crystal has a resonance frequency which is determined by its physical size and the type of quartz it is made of.

The AT-4.000MAHH-T has a frequency stability of 0.2 ppm/°C, meaning that the oscillator frequency will stay within 0.2 ppm of the target frequency over the operating temperature range. This is important because it ensures that devices using the oscillator circuit, such as a car navigation system, will be able to maintain precise timing even in conditions with wide temperature variations.

The AT-4.000MAHH-T also features 0.2 ppm/year aging, meaning that the oscillator frequency will remain stable over time. This means that devices using the oscillator circuit, such as a digital camera or audio equipment, will maintain accurate timing even after extended use.

The AT-4.000MAHH-T can be powered with a continuous DC voltage between 3.2 and 3.6V. This means that it can be used in virtually any application and is compatible with almost all logic families. The output of the AT-4.000MAHH-T is a square wave signal at 4MHz (4000 kHz). This output is suitable for use as a reference clock, or as a timebase for a digital signal processor (DSP) or microcontroller.

The AT-4.000MAHH-T is RoHS compliant and has a small footprint, making it ideal for a variety of applications where size and reliability are important. The crystal unit is also relatively inexpensive, making it the perfect choice for applications where cost is a concern.

The AT-4.000MAHH-T is a reliable, cost effective and versatile crystal unit suitable for use in oscillator circuits in a variety of devices. With its frequency stability and aging characteristics, it ensures that devices using the oscillator circuit will maintain precise timing in a variety of conditions and over an extended period of time.
