MITSUBISHI SOUND PROCESSOR ICs M65850P/FP DIGITAL ECHO(DIGITAL DELAY) 50 SERIES KARAOKE DESCRIPTION ◊ The M65850P/FP is a CMOS IC for generating echo to be added to the voice through a "karaoke" microphone. ◊ It is optimal to provide the echo effect function for karaoke player, such as radio cassette recorders, mini audio components and television sets. ◊ Increased master clock frequency assures high-performance short delay,enabling the IC to be used for dolby prologic surround system. FEATURES Built-in input/output filters, A-D and D-A converters,and memory realize a delay system with only a single chip. Built-in current control type clock oscillator circuit avoids clock affection outside,thus allowing prevention of undesired radiation. Delay time = 164 ms (with master clock set at 1MHz) (Selection of delay time in a range between 15ms and 200ms) Small package (14-pin DIP : 14P4,16-pin SOP:16P2N) Built-in 20Kbit SRAM Built-in auto reset circuit (The IC reset as power is turned on) Single power supply (5V) PACKAGE Outline 1 4 P 4 ( P ) 2.54mm pitch 300mil DIP RECOMMENDED OPERATING CONDITION Supply voltage range Vcc=3.5~5.5V Rated supply voltage Vcc=5V Outline 1 6 P 2 N ( FP ) 1.27mm pitch 300mil SOP SYSTEM CONFIGURATION RAM L VOCAL CUT R HPF LPF HPF KEY CONTROL MIX BASS MIX R MIX BASS...
