The AD6528 Digital Baseband Processor is intended for use in feature-rich GSM/GPRS entertainment cellular handsets. The AD6528 is based on the ADSP-218X DSP core and ARM7TDMI® control processor. It features an extended peripheral interface set eliminating the need for an external application processors. Expanded on-chip, zero-wait-state memory eliminates the need for external SRAM in most applications. The AD6528 can be used to perform full-rate, enhanced full-rate and half-rate, and Adaptive Multi-Rate (AMR) speech codecs as well as a full range of data services including circuit-switched 14.4 kb/s, GPRS to Class 12 and high-speed circuit-switched data (HSCSD). In addition, it supports A5/1 and A5/2 encryption algorithms as well as operation in non-encrypted mode. An entertainment cellular handset can be designed by using the AD6528 along with the AD6535 GSM/GPRS analog baseband processor with power management and stereo audio outputs, and the ADL5551 quad-band GSM/GPRS X-PA™ power amplifier. In addition, a choice of direct-conversion GSM/GPRS/EDGE transceivers is available: the AD6534 Othello One™ or the AD6539 Othello One TV™ with integrated TX VCOs. The VisualFone™ hardware and software development environment supports application development for the AD6528. It includes a Windows®-based software tool for demonstration, evaluation, development and debug of the cellular handset. The hardware includes a baseband evaluation motherboard, baseband-chipset evaluation daughter cards, radio module, telephone handset, power supply, user manuals and RS-232 cables. The AD6528 is available in a 240-ball LFBGA package. A complete data sheet is available under a Non-Disclosure Agreement (NDA) to pre-qualified developers of GSM/GPRS cellular handsets.
