Video Signal Switchers

BA7657S/F, BH7659FS

●Description

The BA7657S, BA7657F, and BH7659FS are ICs that have been developed for use in PC monitors, HDTVs (high definition

televisions), and other high-resolution display devices. In addition to their wide-range switching circuits for RGB signals,

HD signals, and VD signals, the BA7657S and BA7657F feature a separation (BUNRI) circuit for the synchronization signal that

is superposed on the G signal, while the BH7659FS features an on-chip switch for I²C bus signals (SDA and SCL).

These ICs can be used to simplify the input block configuration in advanced display devices.

●Features

1) Operates on 5 V single power supply.

2) Built-in wide-range RGB signal switches.

(BA7657S/F: fc = 230 MHz)

(BH7659FS: fc = 250 MHz)

3) Built-in switching circuit for HD signal and VD signal.

4) Built-in separation (BUNRI) circuit for synchronization signal superposed on G signal. (BA7657S/F)

5) Built-in switch for I²C bus signals (SDA and SCL). (BH7659FS)

6) Built-in power saving function. (BH7659FS)

●Use

PC monitors, Plasma displays, LCD monitors, and Other devices that use wide-range RGB signal switching.
