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.
Outline FEATURES
·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)
