Iijenereyitha zewotshi

I-Infineon inepotfoliyo ebanzi yeejenereyitha zewotshi kunye nenkxaso yefrikhwensi ye-700 MHz kunye ne-RMS yesigaba sejita esingaphantsi kwe-0.7 ps.Baxhasa inkitha yeempawu ezongeziweyo zexabiso ezifana ne-VCXO, i-Spread Spectrum kunye noLungelelwaniso lweSigaba se-Output, kunye neewotshi ezixhasayo zereferensi yemigangatho yojongano oludumileyo njengePCIe 1.0/2.0/3.0, 10 GbE, SATA 1.0/2.0 kunye ne-USB 1.0/2.0 /3.0.Sinemveliso yorhwebo, eyemizi-mveliso kunye neyeemoto.

Iijeneretha zewotshi zinokuhlelwa ngokubanzi zibe ziindidi ezimbini: Ukunciphisa i-EMI (i-Spread-Spectrum capability), kunye ne-Non-EMI Reduction.Usetyenziso ekujoliswe kulo kwezi zixhobo lubandakanya iimoto, ishishini, abathengi, kunye nothungelwano.

Izixhobo zabathengi ziya ziba nezinto ezininzi kwaye ziqhagamshelwe.Ukwabelana ngomxholo wemidiya yesisombululo esiphezulu kufuna imigangatho yokudlulisa idatha ngokukhawuleza, kunye nezixhobo ezinokuxhasa imigangatho emininzi yedatha, nganye ineemfuno ezithile zexesha.Kungenxa yoko le nto siyile i-CY274x High Performance Clock Generator.Ihlangabezana neemfuno zexesha leenkqubo zolwazi lwemoto, izixhobo zonyango, iiprinta zemisebenzi emininzi, iiseva zosasazo zosasazo zemidiya, izixhobo zovavanyo, iinkqubo zekhamera, i-aerospace kunye nokhuselo, kunye nezinye iinkqubo ezininzi.Isixhobo yi-AEC-Q100 efanelekile.

Ii-Frequency Synthesizer

I-frequency-selective frequency multiplier inokwakhiwa ngenkqubo ye-PLL ngokufaka i-frequency divider ngaphakathi kwengxelo phakathi kwegalelo le-detector yesigaba kunye nesiphumo se-VCO.Umzobo ongezantsi ubonisa umzobo weskim se-synthesizer ye-low-frequency synthesizer ene-programmable yamashumi amathathu eminyaka yesekethe yesahluli.

I-frequency-divider modulus N inexabiso phakathi kwe-3 ukuya kwi-999 kunye nenyathelo elinye lokunyuka.Kwimeko etshixiweyo, umthelekisi kunye nomqondiso zikwif=N*1kHZ.Ngoko sine-frequency synthesizer ene-3KHZ ukuya kwi-999 KHZ uluhlu kunye ne-1-KHZ yokunyuswa, enokucwangciswa ngokutshintsha kwendawo yokwahlula-ngo. -n counter.

Esi sekethe sisebenzisa isigaba se-II esithelekisayo kuba i-frequency synthesizer akufuneki itshixeke kwii-harmonics zereferensi ye-signal-input frequency.Asinakusebenzisa isigaba sokuthelekisa I kuba siyatshixa kwiiharmonics.Umlinganisi weSigaba II uhambelana nesi sicelo kuba into esebenzayo yemveliso ye-dide-by-n frequency divider ayikho i-50%.I-VCO imiselwe yi-Phase comparator II,ukugubungela uluhlu lwe-0 MHz ukuya kwi-1.1 MHz.Esi sicelo sineepali ezimbini zeLPF.Ukukhawuleza ukutshixa kutshintsho lwenyathelo lokuphindaphinda kwesi sicelo sine-tag-lead filter.[Umthombo womzobo weSchematic: Ingxelo yeSicelo seZixhobo zaseTexas]
