TE CH T62M99A T62M99A Features Operating voltage: 4.5V ~ 5.5V ADM algorithm Low noise ( -91dB typical) Low distortion rate (0.5% typical) Embedded 48k SRAM Automatic reset function Package type: 16-pin DIP/SOP Digital Sound Processor Embedded 48K Bits SRAM Description The T62M99A is an echo/surround effect processor designed for various audio system applications such as Karaoke, television, VCD/DVD, sound equipment ,..... Etc. It consists of a built-in Voltage controlled Oscillator, Embedded 48Kbits SRAM, A/D and D/A converters as well as echo/surround delay time control logic. The embedded 48Kbits SRAM can generate delay time effect through the external VCO resister control which simplifies the application and make it easy adjustment. Application ! ! ! ! ! ! !
