Crystals:

Crystals are complex solid objects composed of regular and orderly arrangements of atoms, molecules, or ions. They have the ability to convert electrical energy into mechanical energy, and vice versa. This makes them extremely versatile for many applications in radio-frequency (RF) and wireless communications. One such crystal element is the ECS-40.3-20-1X. In this article, we\'ll explore the application field and working principle of this crystal.

Application Field:

ECS-40.3-20-1X crystals are specially designed for use in high-frequency applications. These include radio receivers, signal processors, and oscillators in radio and television transmitters, navigation systems, and satellite communication systems. Other applications include crystal-controlled frequency synthesis and voltage-controlled oscillators (VCXO). They can also be used in frequency-agile applications, such as phase-locked loop (PLL) phase-shift keyed (PSK) and frequency hopping digital radio (FHDR) systems.

Working Principle:

ECS-40.3-20-1X crystals work on the principle of piezoelectricity, which is the ability of certain crystals to convert electrical energy into mechanical energy, and vice versa. The crystal element is composed of multiple layers of quartz, with an interdigitated electrode on each side. When an electrical signal is applied to the electrodes, the quartz vibrates. This vibration changes the electrical signals, thus allowing the crystal to convert voltage into frequency and vice versa.The main frequency of the ECS-40.3-20-1X is 40.3MHz. However, the crystal has an oscillation range that covers 10MHz to 60MHz. The clock amplitude is typically 600mV peak-to-peak and the current consumption is 1.0mA at 40.3MHz.The frequency stability of the ECS-40.3-20-1X crystal is better than ±50ppm over the full operating temperature range. This gives a frequency accuracy of ±3kHz at 40MHz. The maximum operating temperature range of the crystal is from -20°C to 70°C.The ECS-40.3-20-1X is a very high quality, cost-effective crystal element.
