Description
STV83x7
Description
The STV83xy family is the latest TV-dedicated sound processor from STMicroelectronics.
Based on the STV82xy family success, the new STV83x8(US) and STV83x7
(EU/Asia/Middle East/Africa) are specifically intended for the mainstream flat TV market,
paving the way to an enhanced sound experience at the end customer level.
One of the new STV83xy family key functions is to ensure the proper demodulation of
analog broadcasts thanks to its “Autostandard” functionality, a digital automatic standard
search engine.
The demodulation functionality based on the field proven STV82xy family, is highly robust in
all concerned areas, even where overmodulation is dominant.
Five analog audio auxiliary inputs and three auxiliary SCART compliant outputs are
available and aimed at reducing the bill of materials (BOM) by removing audio switches and
buffers.
STV83xy products are designed to fulfill all new digital or hybrid TV digital connectivity
needs thanks to a SPDIF input (bypass only) and two synchronous/asynchronous inter
sound interfaces (I²S). One of the latter supports Dolby Digital 5.1 PCM audio, which
emphasizes on product differentiation by directly driving analog and digital multichannel
outputs. Thanks to this direct drive, TV manufacturers can take full advantage of sound
virtualizers such as TruSurround XT (with TruSurround XT 5.1 Digital differentiated logo)
and ST Omnisurround, or be the first to feature the brand new SRS TruSurround HD
(TruSurround HD 5.1 Digital differentiated logo), which STMicroelectronics is the first to
embed in a mainstream sound processor IC. Should the Dolby decoder only provide a Left
Total/ Right Total (Lt/Rt) signal, an embedded Dolby ProLogic II decoder is aimed to provide
the same output quality as with 5.1 inputs.
New consumer application emergences, in particular the flat screen TV market, bring new
audio challenges to overcome and require more specific dedicated audio compensation
tools such as Smart Volume Control (SVC) compressor/expender on headphone and
loudspeakers, anticlipping, 3-band parametric and 5-band graphic equalizer for a better
acoustic compensation.
In addition to the STV83xy family, a complete digital audio (demodulation, sound processor,
audio amplifier) solution for TV can be used thanks to the ST digital class D amplifier
STA333 family, with additional equalization capability if required.
STMicroelectronics provides a C reference code for the TV controller to facilitate the
integration in the application software.
STV83x7 and STV83x8 are fully hardware and software compatible to answer platform
uniformization strategy.
To support our customers with an efficient evaluation stage, STMicroelectronics provides an
evaluation bundle with board and software, a comprehensive documentation and application
note.
STV83xy products are available in two packages, LQFP100 and LQFP80 14x14. Both are
pin to pin compatible with the previous product generation.
