Working Principle

The HG-2150CA 19.4400M-SVH works by the well-known quartz crystal oscillation principle. In simple terms, quartz oscillates at an extremely high frequency when it is electrically stimulated, allowing it to produce a very precise frequency. The oscillator then amplifies and filters the oscillation, producing a steady signal with little distortion. This makes it ideal for use in timing applications.

The oscillator is built around a quartz crystal, typically cut from a block of synthetic quartz. Quartz crystals have several unique characteristics, including high frequency stability and low temperature coefficients. The crystal is sandwiched between two metal electrodes, which are connected to the amplifier circuit. An oscillating electrical current is created in the crystal, which is then converted into a precise, stable frequency output from the oscillator.

Temperature compensation helps the oscillator to remain stable in varying temperatures. The oscillator’s internal components are designed to account for the effects of changing temperature on the quartz crystal. This ensures that the output frequency will remain consistent despite changes in the temperature of the environment.

The HG-2150CA 19.4400M-SVH is an excellent choice for timing applications that require precision accuracy and minimal jitter. With its temperature compensation feature, it can maintain reliable performance even under extreme temperature conditions.
