Multimedia ICs
Input selector for high resolution
displays
BH7659S / BH7659FS
The BH7659S / BH7659FS are input signal switching ICs developed for high resolution displays that have three fc =
250MHz wide-band video switching circuits for RGB video signal switching and four CMOS analog switching circuits for
switching between HD and VD signals as well as I2C bus signals (SDA and SCL).
zApplications
High-resolution displays and high-definition TVs
zFeatures
1) Operates with a 5V power supply voltage.
2) Built-in, wide-band switching circuit for RGB
switching (fc = 250MHz).
3) SDA and SCL as well as HD and VD signal switching
is possible.
4) Built-in power save function.
