Amajeneretha ewashi

I-Infineon inephothifoliyo ebanzi yamajeneretha ewashi anokwesekwa kwefrikhwensi okungu-700 MHz kanye ne-jitter yesigaba se-RMS engaphansi kuka-0.7 ps.Basekela inqwaba yezici ezengezwe njenge-VCXO, i-Spread Spectrum kanye ne-Output Phase Alignment, kanye namawashi ayireferensi asekela amazinga okusebenza adumile njenge-PCIe 1.0/2.0/3.0, 10 GbE, SATA 1.0/2.0 ne-USB 1.0/2.0 /3.0.Sinemikhiqizo yezentengiselwano, yezimboni neyezinga lezimoto.

Amajeneretha ewashi angahlukaniswa kabanzi abe izigaba ezimbili: Ukuncishiswa kwe-EMI (amandla okusabalalisa i-Spectrum), kanye nokuncishiswa kwe-Non-EMI.Izinhlelo zokusebenza eziqondiwe zalawa madivayisi zihlanganisa ezezimoto, izimboni, abathengi, kanye nokuxhumana.

Amadivayisi ekhasimende aya ngokuya anotha ngesici futhi axhumekile.Ukwabelana ngokuqukethwe kwemidiya kokucaca okuphezulu kudinga amazinga okudlulisa idatha asheshayo, namadivayisi angasekela izindinganiso eziningi zedatha, ngalinye linezidingo ezithile zesikhathi.Yingakho nje siklame i-CY274x High Performance Clock Generator.Ihlangabezana nezimfuneko zesikhathi zezinhlelo ze-infotainment zemoto, okokusebenza kwezokwelapha, amaphrinta emisebenzi eminingi, amaseva okusakaza imidiya, okokusebenza kokuhlola, amasistimu amakhamera, i-aerospace nokuvikela, nezinye izinhlelo zokusebenza eziningi.Idivayisi i-AEC-Q100 Qualified.

Ama-Frequency Synthesizer

Isiphindaphindi sefrikhwensi esikhethayo singakhiwa ngesistimu ye-PLL ngokufaka isihlukanisi samafrikhwensi ngaphakathi kwempendulo phakathi kokufaka komtshina wesigaba kanye nokuphumayo kwe-VCO.Umfanekiso ongezansi ubonisa umdwebo wohlelo lwe-synthesizer ye-low-frequency synthesizer enesekethi yesihlukanisi yeminyaka engamashumi amathathu ehlelekayo.

I-frequency-divider modulus N inenani eliphakathi kuka-3 kuya ku-999 ngokunyuka kwesinyathelo esisodwa.Esimeni sokukhiyiwa, isiqhathanisi nesiginali kufana nef=N*1kHZ.Ngakho-ke sine-frequency synthesizer enobubanzi obungu-3KHZ ukuya ku-999 KHZ ngokunyuka okungu-1-KHZ, okungahlelwa ngokushintsha kokuhlukanisa -n counter.

Lo mjikelezo usebenzisa isiqhathanisi sesigaba II ngenxa yokuthi i-frequency synthesizer akufanele ikhiyelwe kuma-harmonics wemvamisa yereferensi yokufaka isiginali.Asikwazi ukusebenzisa isiqhathanisi sesigaba I ngoba siyakhiya kuma-harmonics.Isiqhathanisi sesigaba II sihambisana nalolu hlelo lokusebenza ngoba isici esisebenzayo sokuphumayo kwe-dide-by-n frequency divider ayiwona ama-50%.I-VCO isethwe yi-Phase comparator II, ukuze ihlanganise ibanga le-0 MHz kuya ku-1.1 MHz.Lolu hlelo lokusebenza lunezigxobo ezimbili ze-LPF.Ukukhiya ngokushesha izinguquko zesinyathelo kwimvamisa lolu hlelo lokusebenza lunesihlungi esihola umaka.[Umthombo womdwebo wohlelo: Umbiko Wesicelo Sezinsimbi zaseTexas]
