Sharaxaada
AD9957 waxa uu u shaqeeyaa sidii I/Q modulator caalami ah iyo kor u kaca kor u kaca ee nidaamyada isgaarsiinta halkaasoo qiimaha, cabbirka, isticmaalka tamarta iyo waxqabadka firfircooni ay muhiim u yihiin.AD9957-ku wuxuu isku daraa Direct Digital Synthesizer (DDS), wax qabad sare, xawli sare 14-bit digital to converter analog (DAC), wareegtada isku-dhufashada saacadaha, filtarrada dhijitaalka ah iyo hawlaha kale ee DSP hal jajab.Waxay ku siinaysaa beddelka band-base-ka-beddelka gudbinta xogta ee habka isgaadhsiinta fiilooyinka ama wireless-ka.AD9957 waa bixinta saddexaad ee qoys ka kooban afar-beddeliyaal dhijitaal ah (QDUCs), oo ay ku jiraan AD9857 iyo AD9856.Waxay bixisaa guulaha waxqabadka xawaaraha hawlgalka, isticmaalka tamarta iyo waxqabadka muuqaalka.Si ka duwan kuwii ka horreeyay, waxay sidoo kale taageertaa habka gelinta taxanaha 16-bit ee xogta kooxda I/Q.Qalabku waxa kale oo loo habayn karaa inuu u shaqeeyo sidii il-sannusoidal hal-tone ah ama sida DAC-da isku xidhan.Wareegga gelinta Clock ee Tixraaca waxaa ka mid ah oscillator-ka kristal, xawaare sare u qaybin-labo gelin, iyo qaylo hoose oo PLL ee isku dhufashada inta jeer ee saacadda tixraaca.
