Application Field

The 416F40625CKT crystal unit is a widely used crystal, typically found within the radio frequency synthesis market. It is strictly designed and intended for use in closed-loop frequency control applications. The 416F40625CKT crystal has been designed to work within a range of frequencies, specifically:

• 153–159.71 MHz (FM)
• 25.8–29.85 MHz (Low VHF)
• 10.2–19.2 MHz (Low MHz)
• 230–250 MHz (ISM Band)
• 470–480 MHz (ISM UHF Band)

The crystal is ideal for use in radio frequency synthesis and is also applicable for use in radio frequency oscillator applications where high frequency stability is necessary. Common applications for the 416F40625CKT crystal include communication systems, mobile phones, public address systems, and computer communications.

Working Principle

A 416F40625CKT crystal is an electromechanical device – meaning it works by using electrical signals to produce mechanical vibrations. The frequency of these vibrations (known as the resonance frequency of the crystal) dictate what frequency the crystal emits. The 416F40625CKT crystal uses a quartz crystal as its resonator, with this quartz crystal having a resonance frequency which is several times higher than that of the electrical frequency used. This means it can convert unusually high frequencies and will remain stable in this conversion process.

The crystal oscillator consists of two electrodes, one of which is connected to the quartz crystal. An electric current passes between the electrodes, passing through the quartz crystal. As the current passes through, the quartz crystal becomes polarized and begins to vibrate as a result of this electric field. This vibration zone is known as the crystal “cut”.

The resonant frequency of the quartz crystal determines how much current is allowed to pass between the two electrodes. As the electrical frequency changes, the current passing between the electrodes changes as well, allowing for precise control. The 416F40625CKT crystal is most commonly used in a voltage-controlled crystal oscillator (VCXO), where the voltage applied to the crystal oscillator controls the resonant frequency. The 416F40625CKT crystal is also suitable for both surface mount and through-hole applications.
