Uqwalaselo lweRhafu yomgca (Isebenza kuwo onke amajelo ngaxeshanye)
Umzobo 6: Ubumbeko lweRhafu yomgca Apha kulapho useta khona ibitrate yazo zonke iitshaneli ezisi-8 ngokuchwetheza kwireyithi oyifunayo. Imenu eyehlayo idwelisa indlela emfutshane kweyona bitrates isetyenziswa kakhulu, nangona kunjalo, awukhawulelwanga kolo luhlu kuphela. Unokukhetha kwakhona igalelo lewotshi. Iwotshi ingaphakathi ngokungagqibekanga. Kuya kufuneka utshintshele kwiwotshi yangaphandle yokutya-ngaphakathi xa ufuna ukulungelelanisa ezimbini okanye ngaphezulu ii-AT4079Bs enye kwenye ngendlela eyinkosi yekhoboka; Kwimeko apho, udibanisa iiwotshi kwikhonkco le-daisy. Emva kokutshintsha ukusuka ngaphakathi ukuya kwiwotshi yangaphandle kwaye ngokuphambanayo, kufuneka ucofe ukufaka isicelo ukuze utshintsho lusebenze (oku kuthatha imizuzwana embalwa).
Imo kunye neClock Out Settings (Faka kuwo onke amajelo ngaxeshanye)
Inkcazo Umfanekiso weskrini "Ref" ichaza ubuninzi bemveliso yewotshi. Lo ngumsebenzi webitrate kwaye uya kwahluka ngokweesethingi zakho zokuphuma kwewotshi phantsi kwe "Mode" menu. Ukwazi ubuninzi bewotshi ekhutshwa yi-BERT kuluncedo xa ufuna ukwenza i-oscilloscope. Ezinye ii-oscilloscopes zifuna amaza ewotshi ngaphezulu kwe-2 GHz. Ukufumana i-AT4079B ukuba ikhuphe loo nto, yiya phantsi koseto lwemowudi kwaye ukhethe iClock ukuze ibe "yiMonitor". Khetha idinomineyitha ukuze isiphumo sibe ngaphakathi koluhlu lobubanzi. Ukutshintsha phakathi kweekhowudi ze-NRZ kunye ne-PAM-4, sebenzisa i-Mode ye-TX useto, emva koko ucofe ku-Sebenzisa. Iinketho zeGrey Mapping kunye ne-DFE pre-coding zifumaneka kuphela kwimodi ye-PAM4. I-DFE Pre-coding ithumela i-pre-amble ye-DFE receiver ukuze ivumelanise ngaphambi kokuba iphethini ye-PRBS yokwenene idluliselwe, ukuphepha ukusasazwa kwempazamo ye-DFE. Ngaba idikhowuda iphumeza inkqubo ye-1+D ngokuphendula i-?=??+? ikhowudi Okwangoku, i-DFE precoding iyazenzekela kwaye ayikhetheki ngumsebenzisi. I-Grey Mapping yenza ukuba kusetyenziswe i-PRBSxxQ echazwe kwi-IEEE802.3bs. Xa imephu yeGrey yenziwe, i-PRBS13 kunye ne-PRBS31 phantsi kwepatheni khetha imenyu ijika ibe yi-PRBS13Q kunye ne-PRBS31Q ngokulandelelanayo. Imephu engwevu icwangcisa kwakhona imephu yesimboli koku kulandelayo: 00 → 0 01 → 1 11 → 2 10 →
Izicwangciso zeSitishi sangaphambili
Unokuzilungelelanisa ezi zicwangciso ngokwetshaneli nganye. Zezi:
Inkcazo Umfanekiso weskrini I-AT4079B inokuvelisa uluhlu olubanzi lweepatheni ezichazwe kwangaphambili. Ukongeza kwiipatheni ze-PRBS, kukho umgca kunye neepatheni zokuvavanya i-jitter. Kwakhona, ngaphezu kweepatheni ezichazwe ngaphambili, umsebenzisi unakho ukucacisa ipateni yakhe - ngakumbi kule ngezantsi. Qaphela: ubhaqo lwemposiso lusebenza kuphela kwiipateni ze-PRBS ezikhoyo kuluhlu oluhlayo lwepatheni ye-RX. Akwenzeki ukwenza ubhaqo lwemposiso kwiipateni ezichaziweyo. Ipateni yesiko yenziwe ngamasimi ama-2 anamagama angama-16 ehexadecimal ngalinye. Umntu kufuneka agcwalise omabini amasimi ngawo onke amagama angama-32 ehex. Wonke umlinganiswa we-hex unamasuntswana ama-4 ububanzi, enza iisimboli ezi-2 PAM4; umzample 0xF yi-1111 ngoko ke kwi-domain ye-PAM e-Grey-coded oku kubangela i-22, kucingelwa ukuba amanqanaba e-PAM achazwe 0, 1, 2, kunye no-3 Ex.ample 2: ukuhambisa umqondiso we-stair 0123, gcwalisa amasimi ngokuphindaphinda kwe-1E
Kwimenu yeRX Pattern, umntu angakhangela zonke iipatheni apho ubhaqo lwemposiso lunokwenzeka. Qaphela ukuba iipateni ze-TX kunye ne-RX kufuneka zifane ukuze ufumane i-RX yokutshixa kwaye ngenxa yoko ukwazi ukwenza imilinganiselo. Kwakhona, ipateni ye-polarity ibaluleke kakhulu kwaye yenza wonke umahluko phakathi kokuba ne-RX PLL yokutshixa okanye ukungatshixwa kwaphela. Unokuqinisekisa i-polarity echanekileyo ngokudibanisa icala le-TX-P lekhebula kwi-RX-P kunye ne-TX-N kwi-RX-N. Ukuba awuwuhloniphi lo mgaqo, usenakho ukuguqula ipolarity kwi GUI kwicala le RX kuphela. Ulawulo lwamehlo angaphakathi nangaphandle lunciphisa amaxabiso aphezulu kunye aphantsi kwiliso lePAM eliphakathi. Amaxabiso okulawula anokwenzeka avela kwi-500 ukuya kwi-1500 yokulawula iliso langaphakathi kunye ne-1500 ukuya kwi-2000 yeso langaphandle. Elona xabiso liqhelekileyo liphakathi kuluhlu. UmzekeloampLe yokutsala useto lwangaphandle luboniswe ngezantsi Okungagqibekanga ampulawulo lwe-litude lulinganiswe kumaxabiso e-millivolt kodwa alukuvumeli ukuba utshintshe izicwangciso zokulinganisa. Ukuba ufuna ukutshintsha i-FFE useto lwempompo, nceda uye ukuze uvule 'Useto oluPhezulu'. Oku kukuvumela ukuba ulawule amaxabiso angaphambili kunye nasemva kogxininiso kumjelo ngamnye, kodwa ampAmaxabiso e-litude akasayi kuboniswa kwi-millivolt. Ngokungagqibekanga, iimpompo ezintathu ziyaboniswa kwaye zinokuhlelwa. Cinga nge ampi-litude njenge-equalizer yedijithali enempompo ephambili, i-pre-cursor (ugxininiso lwangaphambili), kunye ne-post-cursor (i-post-emphasis). Kwimeko eqhelekileyo, ii-pre-and-post-cursors zimiselwe ku-zero; i ampukukhanya kulawulwa kusetyenziswa impompo engundoqo. Ezona ziphambili, zangaphambili, kunye ne-post-mpompo zisebenzisa amanani edijithali aphakathi kwe -1000 kunye +1000. Ukwandisa nokunciphisa i-pre and post-cursors nako kuya kuchaphazela ampimfundo. Nceda uqinisekise ukuba isimbuku se-pre-, isithuba, kunye nee-cursors eziphambili ngu-≤ 1000 ukuze ube nokusebenza ngokupheleleyo. Ukuba inani leempompo lidlula i-1000, umgca wesignali we-TX awukwazi ukugcinwa.
Isiphumo se-Post-cursor kwi-pulse Umsebenzisi unokuhlela i-coefficients yeempompo ezi-7 endaweni yeetephu ezi-3 kuphela ngokucofa kwaye emva koko ujonge ibhokisi yeeTaps Useto: Emva kokufaka useto, ulawulo lwempompo ezisixhenxe luya kufumaneka ukuze luhlelwe phantsi ampimenyu yokufunda. Nayiphi na enye kwiimpompo ezisi-7 inokuchazwa njengempompo engundoqo; kulo mzekelo, iimpompo eziyandulelayo ziya kuba ziziqalekiso zangaphambili. Ngokunjalo, iimpompo ezilandela itephu engundoqo ziya kuba zi-post-cursors. Isiqhekeza yimowudi emiyo. Isikhanyisi esibonakalisayo sisebenzisa amandla amaninzi kodwa siluncedo kumajelo anzima aqulethe utshintsho lwe-impedance
Example Isiphumo seSetingi zangaphakathi nangaphandle
Ukuthatha iMeasurements Bit Error Ratio Reading Ukuze ukwazi ukuqalisa imilinganiselo ye BER, izixhobo zezibuko kufuneka zibekwimowudi ye loopback, nto leyo ethetha ukuba izibuko le TX kufuneka liqhagamshelwe kwizibuko le RX kunye ne PPG kunye ne ED iipateni kufuneka zihambelane. Omnye akafuni ukubonelela nge-PRBS kwisixhobo esifanayo somzimba - umthombo unokuba sisixhobo esahlukileyo kwaye i-error-detector ye-AT4079B inokufumana iwashi yayo kwidatha efunyenweyo (akukho mfuneko yekhonkco yewashi eyahlukileyo). Nangona kunjalo, ukuba ikhowudi yeGrey isetyenziswe kumthombo, umntu kufuneka axelele umamkeli ukuba alindele ukukhowudwa kweGrey ngokunjalo. Ukuba kukho umdlalo kwipatheni, ipolarity, kunye nekhowudi kodwa akutshixwanga, kunokubakho ukutshintsha kweMSB/LSB kwelinye icala.
Ulawulo lwe-BER
Umlinganiselo we-BER unokusebenza kwimodi eqhubekayo kwaye awuyi kuyeka de kube umsebenzisi angenelele kwaye ucofe iqhosha lokuyeka. I-BER inokusekwa ukuba iqhube iyunithi ixabiso elijoliswe kuyo lifikelelwe okanye de kube inani elithile leebhithi lidluliselwe (iiyunithi ze-gigabits ezili-10). Isibali-xesha sivumela umsebenzisi ukuba abeke ixesha lokuba iBER iyeke.
