The infrared remote control mouse consists of the infrared emitter and receiver, whose principle circuit is shown in the figure. The infrared emitter is shown in the figure. IC1 is the encoder integrated circuit VD5026, and it is coupled with VD5027 and VD5028. The 1~8-pin of VD5026 are the address terminals A0~A7, 10~13-pin are the data terminals D0~D3 (when working with VD5028, they can be the address terminals A8~A11), 17-pin is the output terminal of the encoding signal, and its output signal modulates the signals of the 40KHz pulse generator composed of IC2A and IC2D.
