Background information
This full quad-band (850/900/1800/1900) GSM/GPRS solution, a complete hardware/software reference design supplied with all the components for a finished product, supports HR/FR/EFT/AMR codecs. It uses mature, volume-produced technology to assure rapid capitalization and the fastest time-to-market for an optimized solution.
It uses an ARM946-based architecture that runs at 130 MHz and is tuned for multimedia performance. It includes a Release 99 modem compliant with the latest GCF/PTCRB tests, and has been fully validated with a wide range of interoperability testing (IOT). It also offers Single Antenna Interference Cancellation (SAIC) via NXP Mono Interference Cancellation (MIC) technology.
The core system consists of a high-performance baseband, a power management unit (PMU) with a fully integrated battery charger, and a four-band transceiver.
The 5211 is designed for audio performance and delivers a music experience that rivals best-in-class media players. Audio features include MP3 and FM radio in recordable stereo, as well as high-quality, 64-channel polyphonic ringtone generation, Hands Free, and other audio enhancements.
The 5211 reduces power consumption and extends battery life, delivering one of the best autonomy ratings in the market. With a single weekly charge on a 900-mA battery, a 5211-based handset can deliver 20 minutes of voice calling and 40 minutes of music a day – an equivalent of about 18 hours of MP3 or roughly 4.5 hours of video playback.
Advanced power management covers the entire phone, with real-time, software-controlled functions that instantly optimize to current requirements. Also, a DC/DC converter ensures high efficiency for the power supply, and the system supports CCCV charging.
To help customers design the right products quickly, we offer an extensive support network of software engineers and cellular experts working in locations throughout the world, with a particularly strong presence in Asia. We combine this field support with regularly held training sessions, for hands-on learning.
