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.

When the pin EASY/
COM
u
-
= "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.
