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.

•Applications

Video cassette recorders

•Features

1) All the switching functions required for SECAM

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.

•Absolute maximum ratings (Ta = 25°C)
