AD9957BSVZ-REEL IC DDS 1GHZ 14BIT 100TQFP

Tsanangudzo

Iyo AD9957 inoshanda seyepasirese I/Q modulator uye agile upconverter yemasisitimu ekutaurirana uko mutengo, saizi, mashandisiro emagetsi uye kuita kwesimba kwakakosha.Iyo AD9957 inosanganisa yakakwira yekumhanya Direct Digital Synthesizer (DDS), kuita kwepamusoro, kumhanyisa 14-bit dhijitari kune analog converter (DAC), wachi yekuwedzera wedunhu, mafirita edhijitari uye mamwe mabasa eDSP pane imwechete chip.Inopa base bhendi kumusoro-shanduko yekufambisa data mune waya kana isina waya yekutaurirana system.Iyo AD9957 ndiyo yechitatu inopa mumhuri yequadrature digital upconverters (QDUCs), iyo inosanganisira iyo AD9857 uye AD9856.Inopa maitiro ekuita mukumhanya kwekushanda, simba rekushandisa uye spectral performance.Kusiyana nevakatangira, inotsigirawo 16-bit serial yekuisa modhi yeI/Q base band data.Iyo mudziyo inogona neimwe nzira kurongeka kuti ishande senge-toni imwe sinusoidal sosi kana seinopindirana DAC.Iyo Reference Clock yekupinda wedunhu inosanganisira kristaro oscillator, yekumhanya-mhanya kupatsanura-ne-maviri kupinza, uye yakaderera ruzha PLL yekuwedzeredza kwereferensi wachi frequency.
