General Description
STV82x7
10/149
— External audio input interface using 3 x I2S (for decoded streams such as Dolby
Digital
and/or standard stereo streams)
1.1.4
Electrical Features
Multi Power Supply: 1.8 V, 3.3 V and 8 V.
Power Consumption:
●
lower than 1 W in Functional mode (full features)
●
200 mW in Loop-through mode corresponding to Switch-off of all digital blocks
1.2
Typical Applications
The STV82x7 is specified to enable flexible, analog and digital TV chassis design (refer to
Figure 2
,
Figure 3
,
Figure 4
and
Figure 5
).
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,
●
possible application compatibility with STV82x6 (TQFP80 package) TV design,
●
pin-to-pin compatibility with STV82x8 (TQFP80 package) TV design.
The STV82x7 is used to process a single audio source (analog or digital). However, it is possible to
process two audio sources simultaneously using an STV82x7 interconnection (two chips can be
easily connected).
In the case of a single audio source, it is possible to hear and record in the same time: the same
audio stream can be simultaneously output on headphone, loudspeakers, S/PDIF and the SCART
connectors.
Note:
Headphone and loudspeakers can be used simultaneously for dual-language purposes or for
different sound settings (e.g. volume). 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.
