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 3input 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.

·)FAelal turesswitching functions required for SECAM 1 the
CANAL plus decoder integrated onto one chip. 2) Built-in 9-bit serial-to-parallel converter for decoder and TV control reduces number of microprocessor wiring connections required.
3) Inputs have a sync-tip clamp. 4) The switch section can be used independently. 5) Low power consumption off a 5V supply.
