Ñ CMOS90, LFBGA260 (10x10 mm) package including a 128-Mbit stacked DDR-RAM The NXP Nexperia mobile multimedia processor PNX4103 brings advanced, flexible performance to embedded camera applications in multimedia mobile phones. Designed as a co-processor, it can easily interface with any host processor using a standard parallel memory interface. Powered by NXP Trimedia and ARM9 processors, the PNX4103 offers a unique, optimized architecture for addressing top-class multimedia applications like digital still camera, video camcorder, TV-on-mobile and video-conferencing. 90-nm CMOS technology delivers low power consumption and reduced package size.
Audio/Video subsystem A TM3270, the latest Trimedia CPU core, running at 350 MHz, is used to achieve the video performance required in camcorder and DVB-H applications. It can encode baseline H.264 up to VGA or decode main profile H.264 up to D1 resolution, both at 30 fps. To remove unwanted linear and rotational moves, a hardware-based jitter extractor stabilizes all video streams up to D1 resolution before encoding.
Programmable options in the host, sensor, and display interfaces make design-in easier, while advanced image processing functions give the end user a wider variety of features to choose from. The processor also offers several built-in software functions that improve performance, increase design flexibility, and make the imaging functions more user-friendly. Image processing subsystem The PNX4103 includes a dual-sensor interface. For both sensors, parallel and high-speed serial interfaces are available. The main sensor can be CMOS or CCD up to 10 megapixels. The two parallel imaging pipelines
The Trimedia CPU also supports audio codecs as well as advanced algorithms like frame doubling or Smart Color Mapping, which enrich the user
manage both video inputs at the same time for exposure, white balance, video stabilization, contrast enhancement, sharpening, noise reduction, x16 continuous digital zoom, and more. The high-performance and wide range of features of the image processing subsystem transform a mobile phone into a high-end digital still camera.
experience in playback mode. Display subsystem The PNX4103 has a dual-display interface. The primary display interface is dedicated to a RAM-less 24-bit (16M colors) LCD up to Wide-VGA resolution, and supports both parallel and high-speed serial interfaces. The secondary display interface supports RAM-based LCDs up to QVGA (16M colors).

TV out The Analog TV out is compatible with PAL and NTSC standards and supports 4:3 and 16:9 formats. The output can be directly linked to the video inputs of TV sets, set-top boxes or DVD recorders in order to watch still pictures or video, with the possibility of resizing, centering, rotating, or adding overlay objects. Graphics subsystem With the video renderer, it’s easy to perform overlay editing on still pictures or video. The renderer offers up to three independent overlay planes, which can be mixed independently on the two display interfaces and on the TV out streams. The overlay objects can be made of text, icons (JPEG), or 2D objects. These planes support 24 -bit color, alpha blending, and transparency. Video conferencing The PNX4103 can encode and decode two different video streams up to CIF 30 fps at the same time, for video-conferencing purposes. Easy to experience The PNX4103 offers different high-speed interfaces for video-stream exchange and command interfaces. Its firmware is loaded through the communication port after each reset, which makes this solution very easy to upgrade. The simple set of commands and the debug tools package offer designers an easy way to integrate advanced multimedia features. The PNX4103, along with its 128-Mbit DDR SDRAM, is housed in a small (10x10 mm) LFBGA260 package.
