STV82x8

General Description

1.2

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).

Note:

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.
