Majenareta ewachi

Infineon ine yakakura portfolio yewachi jenareta ine frequency rutsigiro rwe700 MHz uye RMS chikamu jitter isingasviki 0.7 ps.Ivo vanotsigira akawanda-akawedzera kukosha maficha akadai seVCXO, Spread Spectrum uye Output Phase Alignment, pamwe nekutsigira mareferensi wachi yeakakurumbira interface zviyero sePCIe 1.0/2.0/3.0, 10 GbE, SATA 1.0/2.0 uye USB 1.0/2.0 /3.0.Tine zvigadzirwa zvekutengesa, zvemaindasitiri uye zvemotokari-giredhi.

Majenareta ewachi anogona kuiswa muzvikamu zviviri: EMI Kuderedza (Kupararira-Spectrum kugona), uye Non-EMI Kuderedza.Zvinangwa zvekushandisa zvezvishandiso izvi zvinosanganisira mota, maindasitiri, mutengi, uye network.

Zvishandiso zvevatengi zviri kuwedzera kupfuma uye zvakabatana.Kugovera yakakwirira-resolution midhiya zvemukati inoda kukurumidza kufambisa data, uye zvishandiso zvinogona kutsigira akawanda data zviyero, imwe neimwe iine yakatarwa nguva yezvinodiwa.Ichi ndicho chikonzero nei isu takagadzira iyo CY274x Yepamusoro Performance Clock Jenareta.Iyo inosangana nenguva inodiwa yemota infotainment masisitimu, michina yekurapa, akawanda-inoshanda maprinta, midhiya nhepfenyuro maseva, bvunzo michina, kamera masisitimu, aerospace uye dziviriro, uye zvimwe zvakawanda zvinoshandiswa.Iyo mudziyo ndeye AEC-Q100 Yakakodzera.

Frequency Synthesizer

A frequency-selective frequency multiplier inogona kuvakwa nePLL system nekuisa frequency divider mukati memhinduro pakati pechikamu che detector yekupinda uye kubuda kweVCO.Mufananidzo uri pazasi unoratidza dhizaini yedhizaini yepasi-frequency synthesizer ine programmable makumi matatu emakore divider circuit.

Iyo frequency-divider modulus N ine kukosha pakati pe3 kusvika 999 ine nhanho imwe chete kuwedzera.Mumamiriro akakiiwa, muenzanisi nechiratidzo zviri paf=N*1kHZ.Saka isu tine frequency synthesizer ine 3KHZ kusvika 999 KHZ renji ine 1-KHZ increment, inogona kurongwa neiyo switch position ye divide-by. -n counter.

Dunhu iri rinoshandisa chikamu chemuenzanisi II nekuti frequency synthesizer haifanire kukiya pane harmonics yechiratidzo-yekupinza referensi frequency.Isu hatigone kushandisa chikamu chekuenzanisa I nekuti inokiya pane harmonics.Phase comparator II inoenderana neichi chishandiso nekuti iyo inoshanda chinhu chekubuda kweiyo divide-by-n frequency divider haisi 50%.Iyo VCO yakaiswa nePhase comparator II, kuvhara huwandu hwe0 MHz kusvika 1.1 MHz.Ichi chishandiso chine mapango maviri eLPF.Kuchimbidza kukiyiwa kwekuchinja nhanho pa frequency iyi application ine tag-lead sefa.[Schematic diagraph source: Texas Instruments Application Report]
