PNX8526

PNX8526 Programmable source decoder with integrated peripherials Rev. 02 — 11 July 2005 Product data sheet 1. General description The PNX8526 is a highly integrated media processor for use in Advanced Set Top Boxes (ASTB) and Digital Television (DTV) systems. The PNX8526 is targeted at the mid to high-end ASTB/DTV systems, decoding ‘all format’ HD and SD MPEG-2 source material with Standard Definition (SD), or double line-rate SD display capabilities. Although the PNX8526 can process high level input formats, its display capabilities are primarily targeted at NTSC, PAL and SECAM televisions. It is also intended for lower cost DTVs, those not considered high definition. Progressive output is also available for double line-rate television displays, or for high resolution graphic content to be displayed on a computer monitor. The PNX8526 is designed in a high performance 0.12 micron process. The PNX8526 performs source decode functions, including conditional access, MPEG-2 transport stream demultiplexing, MPEG-2 video decode, audio decode and processing, graphics generation, video processing, and image composition and display. A 32-bit, 200 MHz VLIW processor, referred to as the TriMedia 3200 CPU core (TM32 CPU), carries out the majority of media processing operations performed by the PNX8526. Fixed function hardware will perform some operations that are not handled by the TM32 CPU. Additionally, the PNX8526 supports a number of peripheral interfaces such as I2C-bus, USB, IDE ...
