DescriptionThe STV6618 is a highly integrated I²C bus-
controlled video switch matrix, optimized for use in
recordable Digital Video Disk applications or DVD
players. It is adapted to video signals with 1H and
2H formats video routings. It provides required for
connections to two external devices (Europe 2
SCARTs), internal tuners, digital encoders and
recorders.

I²C BUS SELECTION STV6618 I²C BUS SELECTIONData transfers follow the usual I²C format; i.e. after the start condition (S), a 7-bit slave address is
sent, followed by an eight-bit data direction bit (W). An 8-bit sub-address is sent to select a register,
followed by an 8-bit data word to be included in the register. The IC’s I²C bus decoder enables the
automatic incrementation mode in write mode.
