STV82x8

General Description

1.2

Note:

Typical Applications

The STV82x8 is specified to enable flexible, analog and digital TV chassis design (refer to Figure 5,

Figure 6, Figure 7 and Figure 8).

The main considerations are:

● all necessary connections between devices can be provided through the TV set,

● pseudo stand-by mode used to copy to VCR or the DVD sources when the TV set is OFF,

● pin compatibility with previous STV82x7 (TQFP80 package) TV design.

The STV82x8 can be used to process dual audio sources (one analog and one digital in parallel).

Headphone and loudspeakers can be used simultaneously for dual-language purpose. In this case,

certain restrictions occur (see Section 4.2: Audio Processing).

For more connections, the SCART-to-SCART path can be used. The use of these full analog paths

implies that the sound is not digitally processed.
