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.

Featuresswitching functions required for SECAM
1) All 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.
