Miniaturization trend in the crystal oscillator industry: 3225 and smaller crystals

Mainstream crystal oscillators are usually divided into two packaging forms: SMD and DIP. SMD crystal oscillators are smaller in size than DIP crystal oscillators and are more widely used in intelligent electronic products. Currently, SMD crystal oscillators with a size of 3225 (3.2*2.5mm) and below are usually used.

How to distinguish active and passive four-pin crystal oscillators

Crystal oscillators are usually divided into two types: passive crystal oscillators and active crystal oscillators. Passive crystal oscillators have two pins, while active crystal oscillators have four pins. However, passive crystal oscillators also have four pins.

The role of 32.768Khz in the circuit

The 32.768Khz frequency is widely used in circuit design, mainly because of its special mathematical characteristics. This frequency value can be easily obtained through simple frequency division to obtain various commonly used time bases.

Smart connected cars are a new hot spot, and the market demand for in-vehicle crystal oscillator applications is rising

Crystal oscillator products, as the "heart" of electronic equipment, have a decisive influence on the overall performance due to their stability and accuracy. In the process of automobile intelligence, crystal oscillator products are not only widely used in vehicle communication, navigation, entertainment and other systems, but also become the key support for core technologies such as intelligent driving and intelligent cockpit.

The precise pulse of low-altitude economy - crystal oscillator

Low-altitude economic aircraft equipment, such as drones and electric vertical take-off and landing aircraft (eVTOL), need to maintain high stability and accuracy under changing climate and temperature conditions. The temperature-compensated crystal oscillator can reduce the impact of ambient temperature changes on the oscillation frequency through the built-in temperature compensation circuit, thereby ensuring that the device can provide a stable frequency reference signal at different temperatures.

How capacitors and resistors work with crystal oscillators

The matching capacitor of the crystal oscillator can be simply called "load capacitor". Imagine that this load capacitor is like a little assistant of the crystal oscillator, helping the crystal oscillator to start working.
