Kufotokozera

AD9914 ndi digito synthesizer yachindunji (DDS) yokhala ndi 12-bit DAC.AD9914 imagwiritsa ntchito ukadaulo wapamwamba wa DDS, wophatikizidwa ndi liwiro lalikulu lamkati, magwiridwe antchito apamwamba a DAC kuti apange makina osinthika a digito, otha kutulutsa ma frequency amtundu wa analogi otulutsa sinusoidal waveform mpaka 1.4 GHz.AD9914 imathandizira kuthamanga pafupipafupi komanso kusanja bwino (64-bit yokhoza kugwiritsa ntchito modulus mode).AD9914 imaperekanso gawo lachangu komanso matalikidwe odumphira.Mawu osintha pafupipafupi komanso owongolera amalowetsedwa mu AD9914 kudzera pa doko lolowera kapena lofananira / lotulutsa.AD9914 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.AD9914 yatchulidwa kuti igwire ntchito pa kutentha kwa mafakitale (onani gawo la Absolute Maximum Ratings).
