Working Principle

The working principle of the 557G-03LF XCO module is based on the quartz crystal oscillator. The quartz crystal oscillator is a resonant circuit that is comprised of two plates of quartz crystal material that are separated by a dielectric. The two plates are electrically connected to electrodes that form the circuit. The quartz crystal plates when supplied with an external signal will oscillate at a specific frequency determined by the equation below.

F = 1/2π(1/C)√ (A/V_m)²,

where F is the oscillation frequency, C is the capacitance between the plates, A is the area of the plates, and V_m is the drive voltage. Once the quartz crystal is oscillating, it is subjected to feedback from a loop of components that are triggered by the oscillation frequency and then used to amplify and maintain the oscillation.

The 557G-03LF module features a 48Hz to 50MHz output frequency range and a small size. It has built-in EMI suppression components and ESD protection, and also features a high stability, low noise, and fast rise/fall time characteristics while maintaining low power consumption.

The module is designed to provide wide frequency range selection and accurate frequency control. It is built with an optimized circuit topology that includes temperature compensation for improved stability over a temperature operating range. The module is able to provide very low EMI which is useful for meeting stringent automotive standards. The built-in ESD protection also helps improve the performance and reliability of the module.
