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 component

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).
