... Video switch for CANAL-Plus decoder BA7630S / BA7630F The BA7630S and BA7630F are decoder switching ICs for the scrambled broadcasts in France. The ICs include a 3- input multiplexer, 2-input multiplexers with 6dB amplifiers, and a 9-bit serial-to-parallel converter. These ICs greatly simplify decoder switching, and can be connected to a control microprocessor using just two lines. ...
