描述 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.
