What are the main characteristics of crystal oscillators?

Jitter is related to phase noise and is measured in the time domain. Usually expressed using effective value (RMS) and peak-to-peak (peak-to-peak), the unit is pS or fS. In fields such as communication networks, wireless data transmission, ATM, SONET, etc., the requirements for jitter and phase noise are often very high.

How much do you know about the classification of commonly used crystal oscillators?

SPXO (Simple Packaged Crystal Oscillator), commonly known as OSC or XO, is a simple crystal oscillator and is widely used. The frequency control element is a quartz crystal, and no other control and compensation means are adopted. Its temperature characteristics are completely determined by the temperature characteristics of the quartz chip.

Electronic technology helps create cars that are friendly to people and the environment

For example, the car is designed with an "adjustable steering wheel" that uses electrodes to measure the heartbeat rate, and an electric-assisted sliding door that reflects the driver's psychological state.

Familiar with the functions of automotive relay switches

The automobile relay switch is the key to controlling the on and off of the circuit. The main switches in the circuit often gather many wires, such as the ignition switch and the main light switch. When reading the diagram, you should pay attention to five issues related to the switch:

Application of electronic control technology

1. Electronically controlled ignition device (ESA) The electronically controlled ignition device consists of a microprocessor, sensors and their interfaces, actuators, etc. This device of the automotive electronic controller performs calculations and judgments based on the engine parameters measured by the sensor, and then adjusts the ignition timing. This device can ensure that the engine operates at an optimal ignition advance angle under conditions such as different speeds and air intakes, so that The engine outputs maximum power and torque, reduces fuel consumption and emissions, saves fuel and reduces air pollution.
