Kufotokozera

AD9915 ndi digito synthesizer yachindunji (DDS) yokhala ndi 12-bit DAC.AD9915 imagwiritsa ntchito ukadaulo wapamwamba wa DDS, wophatikizidwa ndi liwiro lalikulu lamkati, magwiridwe antchito apamwamba a DAC kuti apange makina osinthika a digito, otha kutulutsa mafupipafupi a analogi otulutsa sinusoidal waveform mpaka 1.0 GHz.AD9915 imathandizira kuthamanga pafupipafupi komanso kusanja bwino (64-bit yokhoza kugwiritsa ntchito modulus mode).AD9915 imaperekanso gawo lachangu komanso matalikidwe odumphira.Mawu osinthika pafupipafupi komanso owongolera amalowetsedwa mu AD9915 kudzera pa doko lolowera kapena lofananira / lotulutsa.AD9915 imathandizanso wogwiritsa ntchito momwe amasesera motsatira mzere kuti apange mafunde amtundu wa pafupipafupi, gawo kapena matalikidwe.Liwiro lalikulu, 32-bit parallel data port input imaphatikizidwa, yomwe imapangitsa kuti mitengo ya data ikhale yokwera kwambiri pamakonzedwe a polar modulation ndikukonzanso mwachangu gawo, ma frequency, ndi matalikidwe amawu.
