Oscillators are electronic components which produce continuous periodic electrical signals without any external input. One example is the ASTO-14.31818MHz-EK-T oscillator, which is used in a variety of applications requiring precise frequency and stable output signal generation, especially in clock and timing applications. This article will discuss its application field and working principle.

The ASTO-14.31818MHz-EK-T oscillator is used in applications which require high frequency, precision, and stability. It is often used in clock generation and timing applications, where its precise frequency can be used to accurately synchronize components in a system. The astable oscillator is designed to provide accurate frequency and phase jitter performance with low power consumption. It is suitable for applications such as digital television, digital radio, data communications, medical, automotive, industrial, and consumer applications.

The ASTO-14.31818MHz-EK-T oscillator consists of two elements: a quartz tuning fork crystal and a linear oscillator. The quartz tuning fork is made up of two parallel plates, each with a different thickness and forming opposing ends of the fork. The quartz crystal produces a fixed and stable frequency, which is determined by the thickness of the plates and the physical vibration of the fork. The linear oscillator is composed of transistors or field effect transistors (FETs), which are connected in a feedback loop. The feedback loop amplifies or attenuates the input signal, producing a sine wave output at the desired frequency.

The ASTO-14.31818MHz-EK-T oscillator is designed to operate in the temperature range of -40 degrees Celsius to +85 degrees Celsius, with a tolerance of 2.5 ppm over the temperature range of -20 to +70 degrees Celsius. It has a current consumption of 4.5 mA at +25 degrees Celsius, and a current consumption of 5.8 mA at +85 degrees Celsius, allowing it to be used in a variety of applications requiring energy efficiency. The TTL-output of the oscillator has a logic swing from 0.4V to 2.4V, with an output impedance of 10k-ohm. The sine wave output has a strength of 28mVp-p at 50 ohms, with a jitter of 0.7ps maximum.

In summary, the ASTO-14.31818MHz-EK-T oscillator is suitable for applications requiring precision frequency and stable output generation. It is often used in clock and timing applications such as digital television, digital radio, data communications, medical, automotive, industrial, and consumer applications. Its construction consists of a quartz tuning fork crystal and a linear oscillator, and its current consumption is 4.5mA at +25 degrees Celsius. The oscillator produces a TTL-output of 0.4V to 2.4V, with an output impedance of 10k-ohm, and a sine wave output of 28mVp-p at 50 ohms.
