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. Part Number Examples Part NO.

Revision: A 2.u-COM mode (serial data input) When the pin EASY/ COMu − = “Low” , then in the u-COM mode. The timing is shown as the diagram below: H Delay time H ID code = Sleep mode = Mute This timing chart shows that delay time is set by serial data from u-COM. DATA signal is latched at the falling edge of SCK signal, the last ten datas are set at the rising edge of REQ signal when ID codes are satisfied. ID1, ID3 = Low ID2 = High ID4 = Equal to IDSW
