High-performance Video Signal Switchers Ultra Wide Band Triple Circuits Video Signal Switchers No.11066EAT03 BA7657F,BH7659FS 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 2 G signal, while the BH7659FS features an on-chip switch for I C 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. (BA7657F :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. (BA7657F) 2 5) Built-in switch for I C bus signals (SDA and SCL). (BH7659FS) 6) Built-in power saving function. (BH7659FS) Applications PC monitors, Plasma displays, LCD monitors, and Other devices that use wide-range RGB signal switching.
