AD9957BSVZ-REEL IC DDS 1GHZ 14BIT 100TQFP

Ibisobanuro

AD9957 ikora nka moderi rusange ya I / Q hamwe na agile upconverter ya sisitemu yitumanaho aho ikiguzi, ingano, gukoresha ingufu nibikorwa bikora ari ngombwa.AD9957 ihuza umuvuduko mwinshi Direct Digital Synthesizer (DDS), imikorere ihanitse, umuvuduko mwinshi 14-biti ya digitale kuri analog ihindura (DAC), kugwiza amasaha, kuzunguza amasaha hamwe nibindi bikorwa bya DSP kuri chip imwe.Itanga umurongo fatizo up-guhindura kugirango wohereze amakuru muri sisitemu y'itumanaho cyangwa insinga.AD9957 nigitambo cya gatatu mumuryango wa quadrature digital upconverters (QDUCs), irimo AD9857 na AD9856.Itanga inyungu zunguka mubikorwa byihuta, gukoresha ingufu no gukora ibintu.Bitandukanye nabayibanjirije, nayo ishyigikira uburyo bwa 16-biti byinjira muburyo bwa I / Q base base data.Igikoresho kirashobora gutegurwa kugirango gikore nkisoko imwe ya sinusoidal cyangwa nka DAC interpolating.Inzira yisaha yinjizamo ikubiyemo kristu ya oscillator, umuvuduko mwinshi ugabanywa-by-bibiri byinjira, hamwe n urusaku ruto PLL yo kugwiza inshuro zerekana amasaha.
