ECS-320-8-36-RWN-TR application field and working principle

Crystals are versatile components used for a variety of applications in electrical and electronics engineering. The ECS-320-8-36-RWN-TR is a quartz crystal oscillator designed for precision frequency control in cellular phones, digital cameras, and HDTV receivers. This article will explain its application field, the working principle of crystals, and the particular features of the ECS-320-8-36-RWN-TR.

Application Field of Crystals

Crystals are used in many different applications in fields such as telecommunications, computing, and medical electronics. In telecommunications, for example, crystals are used for precision frequency control of cellular phones, digital cameras, and HDTV receivers. In computers, crystals are used for timekeeping, as well as for frequency generation in microprocessors and other integrated circuits. Other application fields include medical electronics, where crystals are used to generate X-rays, and automotive electronics.

Working Principle of Crystals

Crystals are composed of a mixture of quartz and other minerals. Chemically, quartz is silicon dioxide (SiO2). The quartz crystal is cut in such a way that microscopic electrodes are embedded in it. When an electrical current is applied to these electrodes, the crystal will vibrate at a precise frequency determined by its size and shape. This vibration is known as the “resonant frequency” of the crystal. By properly tuning the electrodes, the crystal can be tuned to generate a very precise frequency.

Features of the ECS-320-8-36-RWN-TR

The ECS-320-8-36-RWN-TR is a 3.2-MHz quartz crystal oscillator designed for frequency control in telecommunications applications. It has an operating temperature range from -30°C to 70°C, a nominal frequency tolerance of ±20 ppm, and an insulation resistance of 5.0 Megaohms. The ECS-320-8-36-RWN-TR also has a high pullability of ±12 ppm, making it suitable for use in applications where a precise frequency is required. The oscillator module can be configured for an 8-pad, 36-pad, or 56-pad arrangement. The 8-pad arrangement is typically used in cellular phones, while the 36 and 56-pad versions are used in high-end digital cameras, HDTV receivers, and other precision electronic devices.
