Crystals: 9C-19.6608MAGJ-T Application Field and Working Principle

Crystals are widely used in various fields, such as radio receivers and transmitters, computers, audio equipment, and oscillators. One of them is a crystal oscillator named 9C-19.6608MAGJ-T, which uses quartz or glass crystal piezoelectric materials suspended inside a metal package. In this article, we will discuss the application and working principle of the 9C-19.6608MAGJ-T crystal oscillator.The 9C-19.6608MAGJ-T oscillator is a type of crystal oscillator that is commonly used in applications requiring a stable output frequency such as automotive, communications, and medical instrumentation. It has a frequency range of 4.3 MHz to 4.9 MHz and a tolerance of ±200ppm. The 9C-19.6608MAGJ-T is housed in a small 9mm x 1.6mm x 0.8mm package and is constructed with a quartz crystal element and discrete factory-trimmed passive components.The working principle of the 9C-19.6608MAGJ-T oscillator can be divided into two general phases. The first phase is called the R-C oscillator phase, during which an RC based circuit is created using an inductor, capacitor, and resistor. The RC oscillator circuit will create a time-varying output. The second phase is the quartz crystal oscillator phase, which uses a quartz crystal to stabilize the RC oscillator signal. The quartz crystal is a piezoelectric material, meaning it deforms under an applied electric field and produces a voltage when deformed. The 9C-19.6608MAGJ-T crystal oscillator utilizes this characteristic to create a precise output frequency. The quartz crystal is connected in series with the external capacitor, inductor and resistor network of the R-C oscillator circuit. The series-connected crystals act like a filter, and by controlling the frequency at which a crystal resonates and will not pass, the output of the oscillator can be tuned to a precise frequency. The oscillator uses a voltage-controlled oscillator (VCO) circuit to generate its output signal. The VCO circuit consists of an amplifier connected to the quartz crystal. When AC power is applied to the VCO circuit, current flows through the quartz crystal and a voltage is generated. This voltage is amplified by the amplifier and applied to the crystal, causing it to vibrate at its resonant frequency. This vibrating crystal then produces a precise output frequency.In addition to its precision output frequency, the 9C-19.6608MAGJ-T crystal oscillator also has a number of other features, such as low power consumption, high stability, low distortion, and low noise. The oscillator can also operate over extreme temperature ranges, from -40°C to +85°C. As we can see, the 9C-19.6608MAGJ-T crystal oscillator is an ideal choice for applications requiring a stable output frequency. Its precise frequency, low power consumption, and high stability make it an ideal choice for automotive, communications, and medical instrumentation. With its wide range of features, it is no surprise that the 9C-19.6608MAGJ-T crystal oscillator is becoming increasingly popular for these applications.
