1 Chip Digital Echo with Microphone mixing Amplifier
DESCRIPTION
The M65855FP is a CMOS IC built-in Digital Echo function with microphone mixing circuits for KARAOKE
equipment packed in a single chip.
It is suitable for KARAOKE equipments such as Video CD Player,Mini stereo,CD Radio cassette,TV or VCR.
FEATURES
• Internal Input/Output low pass filter,A/D,D/A converters,microphone
mixing amplifier,memory achieve a digital echo system with a single
chip.
• High performance digital echo circuit thanks to 20Kbit memory
• Thanks to the improvement A/D,D/A converters,decrease the external
output
• Internal echo mute circuit and echo volume achieve a mixing level
control
