DESCRIPTION

The PT8501 is a complete low-cost decoder for use in the decompression of higher-performance

multi-channel digital audio, such as Dolby Digital (also called AC3). The PT8501 provides a complete

and flexible solution for multi-channel audio decoding in laser-disc players, DVD movie players, stereo

receivers, out-board decoders, HDTV sets, head-end decoders, set-top boxes, and similar products.

PT8501 contains on-chip firmware for decoding and processing DOLBY DIGITAL (AC-3), linear PCM

data. It also includes a Dolby Pro Logic decoder for decoding matrix surround encoded PCM data or

2-ch Dolby digital data. With a built-in S/PDIF receiver, no external S/PDIF receiver is necessary in

order to receive digital bitstreams.

The decoder is controlled via an I²C serial host interface. Standard digital audio data formats are

supported, including I²S, MSB-first right-justified, and MSB-first left-justified.
