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 1 MHz) (Selection of delay time in a range between 15 ms and 200 ms) • Small package (14-pin DIP: PRDP0014AA-A (14P4), 16-pin SOP: PRSP0016DE-A (16P2N-A)) • Built-in 20 Kbit SRAM • Built-in auto reset circuit (The IC reset as power is turned on) • Single power supply (5 V) Recommended Operating Condition • Supply voltage range: V CC = 3.5 to 5.5 V • Rated supply voltage: V CC = 5 V System Configuration L R MIC1 MIC2 Vocal cut HPF MIX RAM MIX MIX L R BASS BASS MIX MIX HPF MIC VOL MIC VOL LPF Key control MIC AMP MIC AMP MIX Echo M65850P/FP Echo VOL Note: Dolby is the registered trademarks of Dolby Laboratories Licensing Corporation. |
