tm TE CH T62M0001A T62M0001A Digital Sound Processor With 64K SRAM Features Description ! ! ! ! ! T62M0001 is a digital echo/surround processor IC utilizing CMOS technology. Analog signal to T62M0001 is digitized by a built-in A/D converter and then stored in the internal memory. After an adjustable delay time, data in the memory is read and converted back to analog signal via the other D/A converter. With the built-in 64K SRAM, T62M0001 can create very high performance echo/surround sound effect and meet the application of A/V system such as CD player VCD,DVD ….etc. ! ! ! Low Noise (-90dBV typical) Low Distortion (0.17% typical) Built –in 64 K SRAM Sleep Mode Function Two Control Modes Selection: Easy Mode Using Parallel Data u-COM Mode Using Serial Data Auto-Mute Function Built-in Automatic Reset Circuit Pin Compatible with M65831 Part Number Examples Part NO.
