TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC9488FG

Digital Echo IC for Karaoke

The TC9488FG is digital echo ICs for karaoke. The ICs

incorporate microphone amps and volume controllers, enabling a

digital echo system to be configured on a single chip.

Features

•

Incorporates a two-channel microphone amp with auto level

control (ALC), AD/DA converter, delay memory, and electronic

volume controllers.

•

Incorporates a 32-kHz sampling, 12-bit successive comparison

AD/DA converter.

Incorporates a delay memory (16-Kbit DRAM) which enables

128-ms (typ.) delay.

Weight: 1.08 g (typ.)

Microphone and echo levels are controlled by built-in volume controllers. They are controlled either by DC

voltage or controlled in serial by the MCU.

TC9488FG: Supports three-lead interface

•

The system clock is generated by the CR oscillator circuit.

The echo feedback amount is configured using analog circuits. The feedback level can be freely set.

The IC comes in 30-pin flat package.
