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.
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)

This time chart shows that delay time is set by serial data from -COM. DATA signal is latches at the falling edge of SCK signal, and the last twelve data are set at the rising edge of REQ signal when ID codes are satisfied*. * ID1 , ID2 : L ID3 :H ID4 : equal to IDSW
Sleep data is H : clock and RAM stop to reduce circuit current (sleep mode) L : normal operation Mute data is H : mute L : not mute

4) ID CODE FLAG When ID codes are satisfied, IDFLAG signal is set on high-level at rising of REQ signal, and it is set on low-level at falling of REQ signal. Each time the REQ signal fall the IDFLAG signal outputs function mode data (input from DATA signal) at the rising edge of the SCK signal.

5) SYSTEM RESET
It is automatic power-on reset, and the reset time is about 120ms. Then delay time is set on 20.0ms.
