Noma yimuphi umugqa uhamba ibanga phezu PCB IBhodi esimweni high isignali imvamisa isignali kubangelwa kwesikhathi esinqunyiwe, ukuqondanisa Oyinyoka injongo eyinhloko "kweqembu elifanayo ezihlobene" alibale ingxenye encane imigqa isignali, lezi zingxenye ngokuvamile hhayi noma esingaphansi nezinye izimpawu ngamanye ukucutshungulwa logic; the ejwayelekile kakhulu umugqa iwashi, ngokuvamile alenzi lutho imuphi omunye logic, ngakho ukubambezeleka salo esingaphansi nezinye izimpawu ezihlobene.
Line Ubude ezifana ngesivinini PCB digitalngoba ukugcina ukubambezeleka umehluko isignali ngalinye ibanga, ukuqinisekisa ukusebenza idatha wokufundwayo ohlelweni esikhathini esifanayo (alibale engaphansi umjikelezo iwashi okungalungile lapho ukufunda idatha lomjikelezo olandelayo), izidingo jikelele alibale umehluko akuyona angaphezu kwezingxenye ezintathu kwezine zobukhulu umjikelezo iwashi, umehluko iyunithi obuphelele ukubambezeleka umugqa iduduzekile, ukubambezeleka nge ububanzi komthetho, umthetho obuphelele, ithusi ukujiya, isakhiwo ipuleti ungqimba, kodwa umugqa lide kakhulu kuzokhulisa ukusatshalaliswa capacitance basakaza futhi inductance, ukwenza isignali izinga ukuhlolwa, ngakho iwashi IC izikhonkwane obanzi RC ukuqedwa, kodwa ukuqondanisa Oyinyoka, hhayi lo inductance indima, kunalokho, i inductance kubangela harmonic ephakeme esigabeni ekuphumeni isibonakaliso sengeta shift, ukwenza izinga isignali ukuwohloka esikalini, ngakho oyinyoka imfuneko okungenani kabili ububanzi umugqa, ukuhlukanisa imigqa, kancane isikhathi ukuvelela isiginali izokhuluma ithonya ukusatshalaliswa yi distrib ezingaba capacitance futhi inductance.
Ngenxa yokuthi izicelo ezahlukene umsebenzi ezahlukene, uma ulayini oyinyoka uvele ngaphambi ibhodi PC , play zako ezisemqoka indima inductance lemifanekiso, nekwenta ncono kunikwa kwemandla anti-ukuphazamiseka wesifunda, futhi oyinyoka umugqa computer umbadlana.
Ikakhulu elisetshenziswa kwezinye amasignali iwashi, ezifana CIClk, AGPClk, okuyinto has imisebenzi emibili:
1. impedance ezifanayo;
2. Hlunga inductance.
Kwamanye amasignali ezibalulekile, ezifana HUBLink ku INTEL HUB izakhiwo, zikhona 13 izimpande, egijima 233MHz, futhi nezidingo kumele igcinwe ngokuqinile isikhathi eside, ukuqeda izingozi ezicashile okubangelwa kubambezeleka, futhi emazombezombe uwukuphela kwekhambi .Ngokuvamile ukukhuluma, izikhala umugqa kwekhoyili inyoka kabili njengoba ububanzi njengoba> = 2.The inyoka umugqa ebhodini PCI liyadingeka ukuzivumelanisa obuphelele ulayini PCI 33MHzClock.In evamile PCB ibhodi Ukukhiqiza , kuba LC okukuhlunga imingcele zisakazwe, futhi angasetshenziswa njengoba ikhoyili inductor radio izimpondo, kanye okufutshane futhi ayibanzi inyoka umugqa ingasetshenziswa ukwenza fuses, njll
