!
!
The T62M0002A is an echo/surround effect
processor. It is designed for various audio
systems including karaoke, television, sound
equipment, etc. The chip consists of a
built-in pre-amplifier, VCO or Voltage
control OSC, Embedded SRAM, A/D and
D/A converters as well as delay time control
logic. Its built-In reply to SRAM can
generate delay time effect and can control the
delay time value through the external VCO
resistor. The VCO circuit can reduce external
components and make it easy to adjust the
delay time.

Function Description
The T62M0002A is an echo/surround effect generator with built-in SRAM. It enaures low
distortion as well as low noise for processing audio signal delay. The chip provides two playing
modes(echo and surround) and the playing function block diagrams are shown as follows.
