Crystals: 9C-48.000MEEJ-T Application Field and Working Principle

Crystals are an integral part of modern electronics and are versatile, if not given too much attention. The 9C-48.000MEEJ-T is one such commonly used device, which has its own set of applications and working principles that are worth exploring.

Crystal oscillators are among the most widely used components in electrical and electronic circuits, primarily due to their performance, ease of use and cost-effectiveness. The 9C-48.000MEEJ-T is a parallel cut cut crystal oscillator popular for high-frequency and frequency-agile systems. This oscillator operates in the frequency range of 48 MHz with a frequency stability of ±50 ppm, as well as a temperature stability of ±20 ppm.

The 9C-48.000MEEJ-T is typically used in telecommunications and other applications requiring high frequency and frequency agility, such as radars, navigation systems, communication base stations, and so on. This quartz crystal oscillator is also suitable for use in digital communication systems, RF and wireless local area networks, Wi-Fi, Bluetooth and more.

The 9C-48.000MEEJ-T is a parallel-cut crystal oscillator with a leaded housing that measures 8.3mm x 8.3mm x 2.5mm. The device works on a frequency of 48 MHz and has a frequency tolerance of ±50ppm for all parameters. The operating temperature range is from -40°C to +85°C. The device also comes with spread-spectrum compatibility and is extremely stable.

The 9C-48.000MEEJ-T operates on the basic principle that when an electric field is applied to a quartz crystal, the crystal will contract and expand, thus causing it to vibrate at a precise frequency. While basic principles remain the same, each crystal oscillator manufacturer uses its own proprietary design and fabrication process to arrive at a specific design that best suits their products.

The process of aligning the silicon along the crystal face, is also known as the electronics manufacturing process. Once the crystal is cut into its desired shape, a thin layer of gold or silver is applied to the crystal\'s surface to make it electromagnetic and then the crystal is mounted on a housing that shields the crystal from external fields.

The 9C-48.000MEEJ-T utilizes a conventional crystal-mounted resonator design and construction process. It features a common 4-pin form factor and high frequency stability and accuracy, so that it can be used in high-reliability embedded applications. The device uses both a Frequency Light Source (FSL) and an Active Crystal Oscillator (ACO) technology to provide high-reliability and accuracy. The FSL system uses a light-emitting diode that measures the resonance of the crystal, while the ACO technology monitors the temperature and provides an output signal with low noise, high linearity and tight frequency accuracy.

The 9C-48.000MEEJ-T is a versatile crystal oscillator that is suitable for a wide range of frequency-dependent applications. The device is small, stable and cost-effective, and is ideal for a variety of communications and radio-frequency applications. Moreover, its stability and accuracy make it well-suited for embedded systems, where precise control of timing and frequency is required.
