ADAU1452WBCPZ-RL IC AUDIO PROCESSOR 72LFCSP

Tsanangudzo

Iyo ADAU1452/ADAU1451/ADAU1450 imotokari inokwanisa odhiyo processors inopfuura nekure iyo yedhijitari siginecha yekugadzirisa masimba ekare SigmaDSP® zvishandiso.Iyo yakagadziridzwa Hardware architecture yakagadziridzwa kuti iite inoshanda audio processing.Iwo maodhiyo ekugadzirisa algorithms anowanikwa mune sampuli-ne-sample uye block-by-block paradigm ayo anogona kuurayiwa panguva imwe chete muchiratidzo chekugadzirisa kuyerera kwakagadzirwa uchishandisa graphical programming chishandiso, SigmaStudio ™.Iyo yakagadziridzwa yedhijitari chiratidzo processor (DSP) core architecture inogonesa mamwe marudzi eaudio yekugadzirisa algorithms kuti aitwe uchishandisa mirairo mishoma pane yaidiwa pazvizvarwa zvakapfuura zveSigmaDSP, zvichitungamira mukuvandudzika kwekodhi kushanda zvakanaka.Iyo 1.2 V, 32-bit DSP musimboti inogona kumhanya pamafrequency anosvika 294.912 MHz uye kuita mirairo inosvika 6144 pasample pachiyero chemuenzaniso we48 kHz.Nekudaro, mukuwedzera kune indasitiri-yakajairwa mareti, huwandu hwakawanda hwemasamputa mareti aripo.Iyo integer PLL uye inochinjika wachi jenareta Hardware inogona kugadzira anosvika gumi neshanu odhiyo sampuli mareti panguva imwe chete.Aya majenareta ewachi, pamwe ne-on-board asynchronous sample rate converters (ASRCs) uye inochinjika hardware odhiyo routing matrix, ita iyo ADAU1452/ADAU1451/ADAU1450 yakanaka audio hubs inorerutsa zvakanyanya dhizaini yakaoma multirate odhiyo masisitimu.Iyo ADAU1452/ADAU1451/ADAU1450 interface ine dzakasiyana siyana analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital audio madivayiri, amplifiers, uye control circuitry, nekuda kwekunyanya kurongeka serial ports, S/PDIF inopindirana (paADAU1452 uye ADAU1451), uye mapini akawanda ekupinza/kubuda.Iwo maturusi anogona zvakare kupindirana zvakananga ne pulse density modulation (PDM) inobuda microelectromechanical (MEMS) maikorofoni, nekuda kweyakasanganiswa decimation mafirita akagadzirirwa chinangwa ichocho.Akazvimiririra muranda uye tenzi I2 C/serial peripheral interface (SPI) control ports inobvumira iyo ADAU1452/ADAU1451/ADAU1450 kwete chete kurongwa uye kugadziridzwa nekunze tenzi mudziyo, asi zvakare kuita se masters inogona kuronga uye kugadzirisa ekunze nhapwa zvishandiso zvakananga.Uku kuchinjika, kwakasanganiswa neself boot functionality, inogonesa dhizaini yemasisitimu akamira asingade chero yekunze yekupinda kuti ishande.
