Multimedia ICs  
KARAOKE echo IC  
BU9253AS / BU9253FS / BU9255FS  
The BU9253AS, BU9253FS and BU9255FS are single-chip ICs that contain all the components needed to configure  
a KARAOKE echo system: an A / D and D / A converter, SRAM, LPF, and mixer for mixing source signals. With  
these ICs, an echo function can be configured easily and with minimum external components.  
Applications  
KARAOKE functions for portable stereo sets, mini com-  
ponent stereo sets, video CDs and DVDs, etc.  
Features  
1) Echo mixing ratio is adjustable with a DC voltage.  
2) A second order LPF can be configured with the  
internal amplifier and an attached capacitor and  
resistor.  
3) Delay time of 131ms. (when fCLK = 357kHz)  
4) Internal mute function.  
5) Single power supply (5V).
