Description
The 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 A7657F 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.
