Infrared receiver infrared receiver chip _ _ _ professional production of infrared receiver company Prudential Coretronic 

 In recent years, Shenzhen Digital Co., Ltd. Cheng Coretronic developed a series of high technology, excellent performance, meet market demand for infrared receiver, and constant innovation, and promote the rapid technological upgrading, product upgrading, always stand infrared receiver in the forefront of the field, more recently made some infrared receiver products, patented technology, is the infrared receiver industry, a unique product. 

 Infrared receiver principle: 

 Infrared remote control signal is a series of binary pulse code. In order to process the wireless transmission interference from other infrared signals are usually the first modulating frequency at a specific carrier, and then transmitted out by the infrared emitting diodes, and infrared receiver will have to filter out other clutter , only to receive the specific frequency signal and reduced to a binary pulse code, that is, demodulation. 

 At present, had prepared for this infrared remote control signal, usually uses the integrated infrared receiver for mediation. Integrated infrared receiver of infrared light-emitting diodes, low-noise amplifier, limiter, band pass filter, demodulator , and the plastic driver integrated circuit, integrated infrared receiver, small size, high sensitivity, small external components, anti-interference ability, easy to use. 

 Infrared remote control transmitter and receiver: 

 Spectrum in the red light, the wavelength of 0.76 ~ 1.5μm, wavelength than the red light is longer, so that the light is called infrared. Infrared remote control is to use infrared to transfer information in a control system, infrared remote control with interference, the circuit is simple, easy encoding and decoding, power consumption and low cost advantages, now almost all video and audio devices support this control way.
