416F37023CKR Application Field and Working Principle

The 416F37023CKR is a quartz crystal oscillator designed and manufactured by USI, Inc. It has become a popular choice for use in consumer electronic products, automotive electronics, and industrial applications due to its inherent stability and closely specifiable frequency performance.

Quartz crystal oscillators are widely used in the electronics industry due to their small size, low cost, and extremely high precision. They are used in such applications as frequency control for radio transmitters and receivers, as well as timing elements for circuits such as microprocessors, digital signal processors and microcontrollers. Quarts crystals are also commonly used as control elements in oscillating circuits as well as in feedback circuits for frequency stabilization.

Operating Principles

The operating principles of quartz crystals are based on the physical phenomenon of piezoelectricity, which is the ability of certain crystals to produce an electric charge in response to mechanical stress. Quartz crystals are especially suited for piezoelectric applications due to their stable and predictable properties. When a voltage is applied to a crystal, it will produce an oscillation at a frequency proportional to the applied voltage. This oscillation is generally referred to as resonance.

The 416F37023CKR is a quartz crystal that can be operated in either a fundamental (fundamental-mode) or overtone (overtone-mode) configuration. The choice of operating mode will affect the frequency stability, temperature coefficient, and the maximum achievable frequency of the crystal. In the fundamental mode, the crystal resonates at the fundamental frequency, which is determined by the crystal cut. In the overtone mode, the crystal resonates at the second, third, fourth, or fifth harmonic of the fundamental frequency.

In order to obtain the desired frequency stability, it is important to select the proper load capacitance for the crystal. The load capacitance must be carefully selected to ensure that the crystal will have the correct frequency at all operating temperatures. Too much load capacitance will reduce the Q, which is the quality factor of the crystal and determines its frequency stability, while too little load capacitance may cause the crystal to stop oscillating.

Specifications and Applications

The 416F37023CKR has a frequency range of 24 MHz to 3.2 GHz, a frequency accuracy of 0.5 to 2 ppm, and a temperature stability of as low as ±0.01 ppm/°C. It is also available in a variety of package styles and footprints. These features make it ideal for use in a wide range of applications, such as cellular phones, automotive electronics, and industrial systems.

The 416F37023CKR is available in either a ceramic or metal package and is RoHS compliant. It also offers a wide operating temperature range(-40°C - +105°C) giving it a very wide range of potential applications. Thus, the 416F37023CKR is an excellent choice for frequency control in consumer electronics, automotive electronics, and industrial applications.
