At present, there are many kinds of chips that can realize infrared emission, and can send different kinds of codes according to selection. Since the launch system is generally powered by batteries, the power consumption of the chips is required to be very low. Most of the chips are designed to be in a sleep state and work only when a key is pressed, which can reduce the power consumption. The crystal oscillator used by the chips should have sufficient resistance to physical impact. Ordinary quartz crystals cannot be used. Generally, ceramic resonators are used. The accuracy of ceramic resonators is not as high as that of quartz crystals, But usually a little error can be ignored
