Crystals are a fundamental building block of electronic solutions, aiding many types of electronic circuits with their ability to respond to external influences under different conditions. CM2012H32768DZFT is one of the most widely utilized frequency control devices in the world and is used in many applications like frequency synthesizers, oscillators, and RF transmitters. Understanding the working principle and application of this crystal will better equip engineers to pick a frequency control device solution to best meet their needs.
The CM2012H32768DZFT is a miniature, low-cost, frequency-control device and works across a wide range of input voltages. It is designed to offer outstanding performance in a compact size, with an extremely low profile of 0.8mm, and provides the highest frequency accuracy. The CM2012H32768DZFT features a wide frequency range of 32.768kHz and is ideal for frequency sources where a low cost, low-profile, and low-power-consumption option is desired.
Its working principle is relatively simple: the crystal vibrates at a specific frequency due to its physical structure, and this vibration is enhanced by an external electrical signal. This vibration is then detected by a piezoelectric transducer, converted into an electrical signal, and fed back to the crystal, which then amplifies the frequency and adjusts it according to the applied electrical signal.
The application of this crystal is diverse. It is a standard component in digital clocks, alarms, and other frequency-dependent systems. It can also be used in electronics equipment to measure time periods, pulses, and detect pulses from bodies like switches. It is also used in mobile phones, satellite navigation systems, wireless communication devices, computers, and remote controls. By generating frequencies for these applications, the CM2012H32768DZFT crystal ensures accurate and reliable operation.
CM2012H32768DZFT is a cost-effective, reliable frequency-control device that provides high accuracy and excellent stability. Its frequency range, size, low power requirements, and low cost make it an optimal choice for a wide range of applications. Understanding its working principle and application will benefit engineers in selecting the best frequency control device for their own system.
