Crystals

Crystals are used in a range of applications, from modern technology to industrial and laboratory equipment. In order to perform their required tasks, crystals are used in frequency control and oscillator circuits, radio transceivers, signal conditioning and timing circuits.

416F270X2ASR application field and working principle

The 416F270X2ASR crystal is a small, highly efficient, surface mount oscillator. It is a frequency-controlled oscillator which utilizes a quartz crystal as the active element. A crystal oscillator is an electronic oscillator circuit that uses a quartz crystal as its frequency-determining element. Quartz has a very high Q value and are used in electronic circuits for controlling frequency and timing. The crystal oscillator produces an output signal with a very accurate frequency, determined by the physical parameters of the quartz crystal used.

The 416F270X2ASR crystal is suited for use in a number of areas, including Bluetooth, WLAN, GPS and other RF applications. It features an extremely low power consumption of only 2.5mA, a very small footprint, and an excellent temperature stability over the rated range of -40 to + 85 centigrade. The 416F270X2ASR crystal also offers excellent stability even in the presence of mechanical and environmental perturbations.

In operation, a crystal oscillator utilizes a quartz crystal in its circuit to control the oscillator frequency. The quartz crystal has the special ability to both vibrate and conduct an electric current, so when electric current is applied, it will vibrate at a specific frequency. This frequency is determined by the physical properties of the quartz crystal and is very stable. In a crystal oscillator circuit, the crystal is connected to two amplifying stages, which increases the amplitude of the vibrations. The output from the amplifying stages is then fed back to the crystal, causing the frequency to remain stable.

The 416F270X2ASR crystal is ideally suited for use in applications where frequency stability and low power consumption are paramount. It is an excellent choice for use in high frequency radios and transceivers, as well as for use in oscillators and other timing circuits.
