The IC is an echo effect generator IC designed for use in a karaoke set.
1. All the functions required for producing echo effects into a single chip. 2. Delay time 100ms (typ.) 3. Few external parts 4. Combined with a 2-channel surround IC(CXA1673), produces full-fledged surround effects. 5. Variable effect volume
1. Integrated digital telephone circuit 2. Programmable rececive gain 3. DTMF/Tone generator and tone ringer 4. Speakerphone Operation 5. Interface to standard telephony transducers
The MT8992, MT8993, MT8993B is an intergrated digital telephone circuit which provides an on-chip HDLC data formatter(H-Phone). Conversion of analog signals to digital PCM and vice versa is accomplished with an on-chip filter codec. Digital signal processing techniques provide speakerphone operation and generation of ringing tone and DTMF signals.
