Product Details

The DTS Neo:X Decoder delivery from ADI has been highly optimised to run on the Analog Devices’ SHARC processor family. The DTS Neo:X decoder operates on PCM data received either through analog/digital input channels or from a decoder module such as DTS 5.1 decoder. The DTS Neo:X Decoder takes channel configurations up to 7.1 input channels and outputs up to 11.1 audio channels. It contains a standard C-callable ‘push’ API. The module has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use.
