Description
STV83x7
Description
STV83xy family is the latest sound processor from STMicroelectronics. Based on STV82xy
family success, the new STV83x8(US) and STV83x7 (EU/Asia/Middle East/Africa) are
particularly intended for the mainstream flat TV market, paving the way to enhanced sound
experience at the end customer level.
One of the new STV83xy family key function is to ensure the proper demodulation of analog
broadcast thanks to its “Autostandard” functionality, a digital standard search engine.
The demodulation functionality based on the field proven STV82xy family, is highly robust in
all concerned area, even where overmodulation is dominant.
Five (5) analog audio auxiliary inputs and three (3) auxiliary SCART compliant outputs are
available and aimed at reducing the bill of material (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 (2) synchronous/asynchronous inter
sound interface (I²S). One of the latter supports Dolby Digital 5.1 PCM audio, which
emphasizes on product differentiation by driving directly analog and digital multichannel
outputs. Thanks to this direct drive, TV manufacturers can fully take 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, which
STMicroelectronics is the first to embed in an IC. Should the Dolby decoder provide only
Left Total/ Right Total (Lt/Rt) signal, an embedded Dolby ProLogic 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-bands 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 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 (2) packages, LQFP100 and LQFP80 14x14. Both
are pin to pin compatible with the previous product generation.
