Multimedia ICs
Video switch for CANAL-Plus decoder
BA7632AF
The BA7632AF is an audio-switching ICs for decoders for scrambled pay channels used in France and other con-
tries. 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.
᭺The BA7632AF has larger termination resistors on the inputs than the BA7631 and BA7631F.
•Applications
Video cassette recorders
•Features
1) All the audio-switching functions required for SECAM
CANNAL-plus decoder integrated onto one chip.
2) Inputs terminated with 140kΩ resistors.
3) Built-in output buffer.
4) Wide supply voltage range (4.5V to 13.0V).
5) Low total harmonic distortion (Max. 0.005% Typ.).
6) Wide dynamic range (3.6Vrms, VCC = 12V).
7) Same control logic as for the BA7630S can be used.
