Infineon muaj cov ntaub ntawv dav dav ntawm lub tshuab hluav taws xob moos nrog kev txhawb nqa zaus ntawm 700 MHz thiab RMS theem jitter tsawg dua 0.7 ps.Lawv txhawb nqa tus tswv tsev ntawm tus nqi ntxiv xws li VCXO, Spread Spectrum thiab Output Phase Alignment, nrog rau kev txhawb nqa cov moos rau cov qauv nrov xws li PCIe 1.0/2.0/3.0, 10 GbE, SATA 1.0/2.0 thiab USB 1.0/2.0 /3.0.Peb muaj cov khoom lag luam, kev lag luam thiab tsheb-qib.

Lub tshuab hluav taws xob moos tuaj yeem muab faib ua ob pawg: EMI Txo (Spread-Spectrum muaj peev xwm), thiab Tsis-EMI Txo.Lub hom phiaj cov ntawv thov rau cov khoom siv no suav nrog tsheb, kev lag luam, cov neeg siv khoom, thiab kev sib txuas lus.

Cov neeg siv khoom siv tau dhau los ua qhov muaj txiaj ntsig zoo thiab txuas nrog.Sib koom cov ntsiab lus kev daws teeb meem siab tshaj plaws yuav tsum muaj cov qauv hloov pauv cov ntaub ntawv sai dua, thiab cov khoom siv uas tuaj yeem txhawb nqa ntau cov qauv ntaub ntawv, txhua qhov yuav tsum muaj sijhawm tshwj xeeb.Qhov no yog vim li cas peb thiaj li tsim lub CY274x High Performance Clock Generator.Nws ua tau raws li lub sijhawm xav tau ntawm lub tsheb infotainment systems, cov khoom siv kho mob, ntau lub tshuab luam ntawv, cov xov xwm tshaj tawm xov xwm, cov khoom siv ntsuas, lub koob yees duab, aerospace thiab kev tiv thaiv, thiab ntau yam ntxiv.Cov cuab yeej yog AEC-Q100 Tsim Nyog.

Zaus Synthesizers

Ib qho kev xaiv ntau zaus tuaj yeem tsim nrog PLL qhov system los ntawm kev ntxig qhov sib faib zaus hauv cov lus tawm tswv yim ntawm theem ntsuas cov tswv yim thiab VCO cov zis.Daim duab hauv qab no qhia txog schematic daim duab ntawm low-frequency synthesizer nrog rau programmable peb xyoo caum divider circuit.

Qhov zaus-divider modulus N muaj nqi ntawm 3 txog 999 nrog ib kauj ruam nce ntxiv.Nyob rau hauv qhov chaw xauv, qhov sib piv thiab cov teeb liab yog tib zaus uas f = N * 1kHZ.Yog li ntawd, peb muaj ib zaus synthesizer nrog 3KHZ txog 999 KHZ ntau yam nrog 1-KHZ increment, uas tuaj yeem ua haujlwm los ntawm kev hloov txoj hauj lwm ntawm kev faib tawm. -n counter.

Qhov Circuit Court no siv theem sib piv II vim hais tias ib tug zaus synthesizer yuav tsum tsis txhob xauv rau harmonics ntawm lub teeb liab input siv zaus.Peb tsis tuaj yeem siv qhov sib piv I vim tias nws kaw ntawm kev sib haum xeeb.Phase comparator II sib haum rau daim ntawv thov no vim tias qhov ua tau zoo ntawm cov zis ntawm qhov sib faib-by-n zaus faib tsis yog 50%.Lub VCO yog teem los ntawm Phase comparator II, kom npog ntau yam ntawm 0 MHz txog 1.1 MHz.Daim ntawv thov no muaj ob-ncej ntawm LPF.Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau hloov pauv zaus hauv daim ntawv thov no muaj tag-cov lim dej.[Schematic daim duab qhov chaw: Texas Instruments Application Report]
