Description
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 V oltage 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. P a r t N u m b e r E x a m p l e s Part NO.
