1 / 12 page TC9488FG 2004-11-19 1 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. • 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. Pin Connection Weight: 1.08 g (typ.) |
