AD9957BSVZ-REEL IC DDS 1GHZ 14BIT 100TQFP

Inkcazo

I-AD9957 isebenza njengemodyuli ye-I / Q yendalo yonke kunye ne-agile upconverter kwiinkqubo zonxibelelwano apho iindleko, ubungakanani, ukusetyenziswa kwamandla kunye nokusebenza okuguquguqukayo kubaluleke kakhulu.I-AD9957 idibanisa isantya esiphezulu se-Direct Digital Synthesizer (DDS), ukusebenza okuphezulu, isantya esiphezulu se-14-bit digital kwi-analog converter (DAC), i-clock multiplier circuitry, izihlungi zedijithali kunye neminye imisebenzi ye-DSP kwi-chip enye.Ibonelela ngesiseko band up-ukuguqulwa ukudluliselwa data kwinkqubo yonxibelelwano ngeentambo okanye wireless.I-AD9957 ngumnikelo wesithathu kwintsapho ye-quadrature digital upconverters (QDUCs), equka i-AD9857 kunye ne-AD9856.Inika iinzuzo zokusebenza kwisantya sokusebenza, ukusetyenziswa kwamandla kunye nokusebenza kwe-spectral.Ngokungafaniyo nabanduleli bayo, ikwaxhasa imowudi ye-16-bit ye-serial yokufakwa kwedatha yesiseko se-I / Q.Isixhobo sinokulungiselelwa ukuba sisebenze njengethoni enye yomthombo we-sinusoidal okanye njenge-DAC edibanisayo.I-Reference Clock input circuitry ibandakanya i-crystal oscillator, i-high speed divide-by-two input, kunye ne-PLL yengxolo ephantsi yokuphindaphinda i-clock frequency yereferensi.
