MITSUBISHI SOUND PROCESSOR ICS

M65830BP/FP

DIGITAL DELAY

DESCRIPTION

The M65830B is a CMOS IC developed to produce surround effects on TV sets and video

disc players.Among the series,it has the highest degree of freedom in the selection of

delay time,so it permits fine adjustments when mounted on a set.

FEATURES

Outline

•Selection of delay time in a range between 0.5msec and

32.0msec in 64 increments of 0.5msec

•Selection of delay time is controlled by serial data

•Built-in A-D, D-A converters,input/output low-pass filter,

and 16K bit memory

•High sound quality is assured by simple system

construction,due to A-D, D-A converters with ADM

(Adaptive Delta Modulation) system

Output noise voltage : -95dBV (typ)

Total harmonic distortion : 0.2% (typ)
