The PNX6712 delivers superior voice quality and industryleading standby times. It supports quad-band 2G and tri-band 3G operation, plus HSDPA/EDGE (HEDGE).
It uses an ARM926-EJ processor, manufactured in a powerefficient, 65-nm CMOS process technology, that runs at 312 MHz and is supported by 32 kB each of instruction and data cache. For maximum flexibility, the ARM processor is complemented by two 16-bit DSP cores that can be programmed to keep pace with evolving algorithms and
new codecs. The on-chip modem delivers EGPRS Class 12 performance, with DTM class 5/9/11 and single antenna interface cancellation (SAIC).
NXPs Nexperia Cellular Multimedia Baseband PNX6712 outperforms existing HSPA-EDGE basebands in its category by combining best-in-class multimedia features, up to 750 hours of standby, 45 hours of MP3 and 8 hours of video playback, and a multitude of connectivity options for anytime, anywhere content transfer. The solution provides manufacturers a platform for high-performance multimedia phones, with a highly flexible and efficient architecture built around an ARM926-EJ processor, unique algorithms for voice and video, hardware accelerated low-power video, graphics and camera features, and built-in security and digital rights management (DRM).
Packaged into a 12x12mm footprint with a 0.4mm pitch, NXPs Nexperia Cellular Multimedia Baseband PNX6712 features single-core architecture, eliminating the need for an external multimedia co-processor. It supports the latest audio and video codecs, four microphone inputs for better voice quality, two class-D amplifiers for clear sound, W/QVGA display interfaces, and TV-out functionality. All these features are supported by over 10 connectivity interfaces, including USB Hi-Speed OTG, SDIO, SPI, most memory cards as well as system level extensions for A-GPS, NFC, BT, FM, for seamless sharing of content. The PNX6712 forms the engine of NXPs Nexperia Cellular System Solution 6712 - a powerful HSDPA/HSUPA/EDGE platform, enabling sub-$30 electronic bill-of-materials (eBoM).
