Passive crystal oscillator selection

As an important component of the clock circuit, the performance of the passive crystal oscillator directly affects the stability and accuracy of the entire system. The passive crystal oscillator itself does not have an internal oscillation circuit and relies on an external circuit to generate oscillation. Therefore, choosing a suitable crystal oscillator and ensuring that its parameters match the circuit are the key to achieving efficient and stable operation. The following are several main parameters that affect the performance of the passive crystal oscillator:

YXC crystal oscillator solutions help industrial camera applications

In each module of an industrial camera, the crystal oscillator (Crystal Oscillator) provides an accurate clock signal, which is mainly used to ensure that each part of the system can operate synchronously and ensure the stability and correct processing of the signal. Different modules have different requirements for the frequency, accuracy, temperature stability and other parameters of the crystal oscillator.

The difference between active crystal oscillators and passive crystal oscillators

Passive crystal oscillators are mainly used in low-cost communication equipment, toys and small electronic products; active crystal oscillators are mainly used in audio and video equipment, industrial automation and control equipment, etc. The difference between active crystal oscillators and passive crystal oscillators is shown in the table below:

Optical modules remain popular, with the best time-frequency CP-differential crystal oscillator

A crystal oscillator, or quartz crystal oscillator, is a component used in electronic devices to generate stable oscillation signals. In optical modules, the main function of the crystal oscillator is to provide high-precision clock signals and frequency control to ensure that the optical module maintains stability and reliability during high-speed transmission. The performance of the crystal oscillator directly affects the key parameters of the optical module, such as transmission rate, transmission distance, power consumption and volume.

Working Principle of Crystal Resonator

A quartz crystal oscillator is a resonant device made using the piezoelectric effect of a quartz crystal. Its basic structure is as follows: a thin slice is cut from a quartz crystal at a certain azimuth angle (the commonly used wafer cuts are divided into two types: AT cut and BT cut), silver is plated on its two corresponding surfaces as electrodes, a lead is welded on each electrode and connected to the pin, and then a package shell is added to form a quartz crystal resonator, referred to as a quartz crystal or crystal.

The role of the crystal oscillator in the 5G base station is to provide a precise signal source to cooperate with it, so as to achieve the purpose of high-speed data transmission (exchange) between devices through network channels in a collaborative mode.
