PNX170x
General Description
Continuing a tradition of low-cost, high-performance, real-time media processors, the Nexperia PNX1700 handles popular video, audio, graphics, and communications standards such as H.264,Windows Media Technology, DivX, MPEG-2, MPEG-4, MP3, Dolby Digital, TCP I/P, Ethernet, and Universal PnP. Doubling the performance of the PNX1500, the PNX1700 also decodes HD video formats including WMV9, MPEG-2, and DivX-HD. Support for simultaneous encode/decode of MPEG-2 or MPEG-4 formats enables features such as watch/record and time-shifting in DVRs. The PNX1700 maintains 100% pin compatibility with the PNX1500, ensuring design re-use as well as an instant performance boost for existing PNX1500 designs.
The PNX1700 features a TriMedia TM5250 CPU core with an enhanced set of powerful multimedia and floating point instructions. Its on-chip I/O and co-processing units perform high-quality hardware image scaling, advanced de-interlacing, picture enhancements, and complex 2D graphics acceleration. A TFT LCD controller and an Ethernet 10/100 MAC reduce the BOM and support advanced product configurations. Together the CPU and on-chip units make PNX1700 an ideal single-chip solution for delivering exceptional picture quality in a variety of connected multimedia appliances such as digital media adapters, IP STBs, personal media players, and more.
The PNX1700 is supported by a comprehensive software development environment, enabling application development entirely in the C or C++ programming languages. Extensive applications libraries, developed by Philips and third parties, improve time-to-market, reduce design cycles, and lower product development costs.
