I-AD9957BSVZ IC DDS 1GHZ 14BIT 100TQFP

Incazelo

I-AD9957 isebenza njengemodelitha ye-I/Q yendawo yonke kanye ne-agile upconverter yezinhlelo zokuxhumana lapho izindleko, usayizi, ukusetshenziswa kwamandla nokusebenza okuguquguqukayo kubalulekile.I-AD9957 ihlanganisa i-Direct Digital Synthesizer (DDS) enesivinini esiphezulu, ukusebenza okuphezulu, isivinini esiphezulu se-14-bit digital to analog converter (DAC), iwashi eliphindaphindayo, izihlungi zedijithali neminye imisebenzi ye-DSP ku-chip eyodwa.Ihlinzeka ngokuguqulwa kwebhendi eyisisekelo yokudluliselwa kwedatha kusistimu yokuxhumana enezintambo noma engenantambo.I-AD9957 ingumnikelo wesithathu emndenini wama-quadrature digital upconverters (QDUCs), ohlanganisa i-AD9857 kanye ne-AD9856.Inikeza izinzuzo zokusebenza ngesivinini sokusebenza, ukusetshenziswa kwamandla nokusebenza kwe-spectral.Ngokungafani nabangaphambi kwayo, iphinde isekele imodi yokufaka yochungechunge engu-16-bit yedatha yebhendi ye-I/Q.Lolu cingo lungase luhlelwe ukuthi lusebenze njengomthombo we-sinusoidal onethoni eyodwa noma njenge-DAC ehlanganisayo.I-Reference Clock input circuitry ihlanganisa i-crystal oscillator, okokufaka kwesivinini esikhulu sokuhlukanisa kabili, kanye ne-PLL yomsindo ophansi yokuphindaphinda imvamisa yewashi lesithenjwa.
