General Description
The HT8970 is an echo/surround effect processor.
Itisdesignedforvariousaudiosystemsincluding
karaoke, television, sound equipments, etc. The
chip consists of a built-in pre-amplifier, VCO or
Voltage Control OSC, 20Kb SRAM, A/D and D/A
converters as well as delay time control logic.
Its built-in 20Kb SRAM can generate delay
time effect and can control the delay time value
through the external VCO resistor.
The VCO circuit can reduce external compo-
nentsandmakeiteasytoadjustthedelaytime.
