Circuit description 8553T 8553T工作原理包括发射与接收两个过程。主控芯片SN93331会把放大了的声音模 拟信号进行数模转换，连同镜头芯片GC0308出来的图像数字一起打包后，把数据传送调制/ 解调电路UR2调制成射频信号，经过SST12LP放大电路及滤波LC电路后，从天线发送出 去。 一旦相应的接收器收到这个信号，会进行核对编码后，返回应答信号给8553T。 8553T收到应答信号后，经过滤波及低噪放大（BFG425）处理，然后经过解调（UR2） 进入主控识别，若识别正确后，8553T会继续发送声音、图像信号。 There are transmitting and receiving procedure in 8553T working flow. First, MCU-SN93331 will quantify the amplified sound signal, pack them with digital video signal from-GO0308, then send to modulating/demodulating circuit(UR2) in order to corresponding RF signal. The signal will be amplified by SST12LP and go through filter LC, then emit by antenna. Receiver will verify data and acknowledge 8553T once signal is received. If 8553T got the acknowledging signal, then signal will be preceded with filtering and low noise amplifying (BFG425). After that, signal will go on being demodulated and input to MCU to be recognized. 8553T will continue to transmit sound, video signal if correct.
