T62M0001A
Digital Sound Processor
With 64K SRAM
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.
