Crystals are essential components in various electronic circuits. Perhaps the most common crystal used in digital circuits is the FA-128 37.4000MF10Y-AC5. This type of crystal is widely used in applications from portable internet devices to embedded systems. In this article, we will discuss the application field and working principle of the FA-128 37.4000MF10Y-AC5.

The FA-128 37.4000MF10Y-AC5 is a precision quartz crystal oscillator designed to provide a reliable, accurate clock signal to time-sensitive digital circuits. Its application field covers frequency stability and fast access to a stable clock. It is ideal for applications that require precise timing, such as precision timers, clock generators, temperature sensors and electronic instruments. This type of crystal is also ideal for calibrating oscillators, digital clocks and watches, data transmission and receiving, and many other circuits.

In terms of its working principle, the FA-128 37.4000MF10Y-AC5 is composed of two precisely cut quartz crystal plates that are positioned in a parallel formation and connected via a metallic frame. When a voltage is applied to the crystal plates, the quartz plates vibrate. The oscillation is sustained by the electrical lubrication effect of the quartz crystal plates. This oscillation creates an electromagnetic field that is used to generate a precise frequency output.

The oscillator circuit of the FA-128 37.4000MF10Y-AC5 consists of an amplifier, a driver and a feedback loop. The amplifier amplifies the voltage applied to the quartz crystal and the driver controls the amplitude of the oscillation. The feedback loop receives the signal and compares it to a reference voltage, feeding back a voltage to the driver to adjust the amplitude as needed.

The oscillator circuit also contains a temperature sensor. The temperature sensor ensures that the crystal will not produce a signal with a frequency that is too high. This is important because some devices in digital circuits may be sensitive to changes in frequency, resulting in faulty operation. As the temperature of the environment changes, the oscillator circuit automatically adjusts itself to maintain the same frequency output.

In terms of performance, the FA-128 37.4000MF10Y-AC5 has a wide frequency range from 5KHz to 40MHz. It also has excellent frequency stability and can maintain frequency accuracy of -4ppm to +4ppm over a wide temperature range. The device also has high startup and stop time performance, low power consumption and wide supply voltage range.

All in all, the FA-128 37.4000MF10Y-AC5 is an ideal choice for high-precision clock generation and time-sensitive digital applications, such as precision timers, clock generators and temperature sensors. With its wide frequency range, excellent frequency stability and high performance, it is no wonder the FA-128 37.4000MF10Y-AC5 is the crystal of choice for many engineers.
