Specification for CD
Signal that movement read send U D E interface circuit into, decode chip
(SPHE8104 ) decode, reduce the video signal of simulation and digital
audio frequency signal, SPHE8104 export among them. Digital audio
frequency signal send
into , carry on audio frequency D / A output 5.1 sound channel analog
signals change , export after it is low and open to strain the wave. Three
primary conditions that must possess are to decode the circuit and work
normally: Power , clock and signal of restoring to the throne. Need
memory come , store certain information at the same time, F L A S H R O
M flash memory soon, mainly used for storing greetings , , working the little
yard of orders and user's information
etc., S D R A M is a random access memory, mainly used for storing the
data before and after decoding , plays a buffering role.
