Video switch for CANAL-Plus decoder
BA7631 / BA7631F
The BA7631 and BA7631F are audio-switching ICs for decoders for scrambled pay channels used in France and
other countries. The ICs include a five-input multiplexer, a four-input multiplexer and a two-input multiplexer, and
allow decoder audio switching to be done with a single IC. When used in combination with the BA7630S common
logic control can be used for audio and video switching.
•^Applications
Video cassette recorders
•^Features
1) All the audio-switching functions required for SECAM
CANAL -plus decoder integrated onto one chip.
2) Inputs terminated with 65kΩ resistors.
3) Built-in output buffer.
4) Wide supply voltage range (4.5V to 13.0V).
5) Low total harmonic distortion (0.005% Typ.).
6) Wide dynamic range (3.6Vrms, VCC = 12V).
7) Same control logic as for the BA7630S can be used.
