Mawotchi Amagetsi

Infineon ali ndi mbiri yotakata ya mawotchi opangira mawotchi omwe amathandizidwa pafupipafupi ndi 700 MHz ndi RMS gawo jitter yochepera 0.7 ps.Amathandizira zinthu zambiri zowonjezera monga VCXO, Spread Spectrum ndi Output Phase Alignment, pamodzi ndi mawotchi ochiritsira amitundu yodziwika bwino monga PCIe 1.0/2.0/3.0, 10 GbE, SATA 1.0/2.0 ndi USB 1.0/2.0 /3.0.Tili ndi zinthu zamalonda, zamakampani komanso zamagalimoto.

Majenereta a mawotchi amatha kugawidwa m'magulu awiri: EMI Reduction (Spread-Spectrum capability), ndi Non-EMI Reduction.Zomwe zimagwiritsidwa ntchito pazidazi zimaphatikizapo magalimoto, mafakitale, ogula, ndi maukonde.

Zipangizo zamakasitomala zikuchulukirachulukira komanso zolumikizidwa.Kugawana zofalitsa zamtundu wapamwamba kumafuna miyezo yofulumira yotumizira deta, ndi zipangizo zomwe zingathe kuthandizira miyezo yambiri ya deta, iliyonse ili ndi zofunikira zenizeni za nthawi.Ichi ndichifukwa chake tidapanga CY274x High Performance Clock Generator.Imakwaniritsa zofunikira zanthawi yama infotainment yamagalimoto, zida zamankhwala, osindikiza amitundu yambiri, maseva owulutsa pawailesi yakanema, zida zoyeserera, makina amakamera, zakuthambo ndi chitetezo, ndi zina zambiri.Chipangizocho ndi AEC-Q100 Woyenerera.

Frequency Synthesizer

Makina ochulukitsa osankha pafupipafupi amatha kupangidwa ndi dongosolo la PLL poyika chogawa pafupipafupi mkati mwa mayankho pakati pa chowunikira chagawo ndi kutulutsa kwa VCO.Chithunzi chili m'munsichi chikuwonetsa chojambula chotsika pafupipafupi chokhala ndi cholumikizira chazaka makumi atatu.

Ma frequency-divider modulus N amakhala ndi mtengo pakati pa 3 mpaka 999 ndi masitepe amodzi.Pamalo okhomedwa, chofananira ndi siginecha zimakhala pafupipafupi ngati f=N*1kHZ.Chotero tili ndi ma frequency synthesizer okhala ndi 3KHZ mpaka 999 KHZ osiyanasiyana ndi 1-KHZ increment, yomwe imatha kusinthidwa ndikusintha kwagawo-ndi. -n counter.

Derali limagwiritsa ntchito gawo lofananira II chifukwa chophatikizira pafupipafupi sayenera kutseka pamayendedwe amawu amtundu wa ma sign-inpure.Sitingagwiritse ntchito gawo lofananira I chifukwa limatseka ma harmonics.Phase comparator II imagwirizana ndi izi chifukwa chomwe chimagwira ntchito pagawo logawa pafupipafupi si 50%.VCO imayikidwa ndi Phase comparator II, kuti ikwaniritse 0 MHz mpaka 1.1 MHz.Pulogalamuyi ili ndi magawo awiri a LPF.Kuti mutseke mwachangu kuti musinthe masitepe pafupipafupi pulogalamuyi imakhala ndi zosefera zotsogola.[Gwero lachithunzithunzi: Texas Instruments Application Report]
