CXA1645M is three colors coding integrated circuit of VCD prodcued by SONY,which is widely used in SONY, Samsung and Sharp VCD. First,Inner Circuit Block Diagram CXA1645M internal includes color TV signal P/N coding system function and it can output video P/N system full TV signalor blue separation S terminal output signal as long as R, G, B three colors signal and composite synchronous pulse signal are input.The two kinds of output in IC internal have buffer amplifier and the best load is 75 Ω. CXA1645M internal does not set color coding of special color subcarrier oscillator.The special negative carrier generating circuit is used when it is used in the VCD.
