SMARTi
low-cost, highly integrated quad-band single chip GSM/GPRS/EDGE CMOS transceiver GSM850/GSM900/GSM1800/GSM1900 voice high performance data transfer applications. industry leading EDGE CMOS transceiver, SMARTi designed power consumption high integration. Featuring digital interface fully compatible with DigRF V1.12 standard, SMARTi integrates analogue blocs solution, thus interfacing with fully digital base band components. Zero direct conversion receiver quad-band polar modulator transmit path EDGE with integrated functionality. Further comprises completely integrated digital -synthesizer with HSCSD GPRS/EDGE capability, digitally controlled reference oscillator with three outputs fully integrated quad-band oscillator (VCO). Power amplifier ramping control functions, front-end switch control signals complete SMARTi PM2. complete radio digitally controlled embedded micro-controller through DigRF interface SMARTi PM2, thus ensuring optimal control radio fully digital Base Band solutions. architecture SMARTi ensures easy-to-use EDGE solution enabling very size-effective engine implementation.
