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)
