GUI Ngaphezuluview
Kwisixhobo sakho se-GUI, kukho iindawo ezininzi zolawulo ezichazwe ngezantsi.
Isixhobo sokuQhagamshela indawo
Into yokuqala ofuna ukuyenza kukuqinisekisa ukuba uqhagamshelwe kwisixhobo. Ukuba unjalo, iqhosha lokudibanisa liya kufunda Ukuqhawula kwaye i-LED eluhlaza ilayite.
Isitshixo se-PLL kunye neNdawo yoBume bobushushu
Gcina iliso kwii-LED kunye nokufundwa kobushushu kule ndawo. I-TX Lock ithetha ukuba i-PLL yePPG itshixiwe. Isitshixo se-RX siluhlaza kuphela ukuba uphawu lwe-polarity oluchanekileyo kunye nohlobo lwe-PRBS lufunyenwe kwisichongi-mpazamo.
Ukuba iqondo lobushushu lifikelela kuma-65°C, i-electronics iya kuvala ngokuzenzekelayo.
Ukufunda uHlaziyo lweFirmware efakiweyo
Inguqulo ye-firmware efakiweyo iboniswe kwikona ephezulu ngasekunene ye-GUI.
Uqwalaselo lweRhafu yomgca (Isebenza kuwo onke amajelo ngaxeshanye)
Apha kulapho useta khona ibitrate yazo zonke iitshaneli ezi-4. Unokukhetha kwakhona igalelo lewotshi. Iwotshi ingaphakathi ngokungagqibekanga. Kuya kufuneka utshintshele kwiwotshi yewotshi yangaphandle kuphela xa ufuna ukulungelelanisa ii-AT4039E ezimbini okanye ngaphezulu enye kwenye ngendlela eyinkosi yekhoboka; Oku kuphunyezwa ngokuseta uqwalaselo oluchanekileyo lwe-jumper kwi-backplane ye-AT4000. 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
I-"Ref" ibonisa ukuphindaphinda kwemveliso yewotshi. Lo ngumsebenzi webitrate kwaye uya kwahluka ngokoseto lwakho lokuphuma kwewotshi phantsi kwe "Mode" menu. Ukwazi ubuninzi bewotshi ekhutshwa yi-BERT kuluncedo xa ufuna ukwenza i-oscilloscope. Ezinye ii-oscilloscopes zifuna i-clock frequency ngaphezulu kwe-2 GHz. Ukufumana i-AT4039E ukuba ikhuphe loo nto, yiya phantsi kweesetingi zemowudi kwaye ukhethe iClock ukuze ibe "yiMonitor". Khetha idinomineyitha ukuze isiphumo sibe phakathi koluhlu lomda. Kwimeko ye-AT4025, i-Ref Clk isetyenziselwa ukuvelisa iwashi ukusuka kwicala le-AT4039E.
Ukutshintshela phakathi kwe-NRZ kunye ne-PAM-4 ikhowudi, sebenzisa i-TX Mode useto, uze ucofe ku-Sebenzisa. Iinketho zeGrey Mapping kunye ne-DFE pre-coding zifumaneka kuphela kwimodi ye-PAM4. I-DFE Pre-coding ithumela i-pre-amble for DFE receiver to sync ngaphambi kokuba ipateni ye-PRBS yokwenene idluliselwe, ukuphepha ukusasazwa kwempazamo ye-DFE. Idikhowuda isebenzisa iskimu sika-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 ivuliwe, 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 → 3
Izicwangciso zeSitishi sangaphambili
Unokuzilungelelanisa ezi zicwangciso ngokwesiseko setshaneli nganye. Zezi:
Inkcazo
I-AT4039E inokuvelisa uluhlu olubanzi lweepatheni ezichazwe kwangaphambili. Ukongeza kwiipatheni ze-PRBS, kukho umgca kunye neepatheni zokuvavanya i-jitter. Kwakhona, phezu kweepateni ezichazwe kwangaphambili umsebenzisi unethuba lokuchaza ipateni yakhe - ngakumbi kule nto ingezantsi.
Phawula: 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 eziyi-2 PAM4; umzample 0xF yi-1111 ngoko ke kwi-domain ye-PAM ene-Grey-coded oku kubangela i-22, kucingelwa ukuba amanqanaba e-PAM achazwe 0, 1, 2 kunye no-3 Ex.ample 2: ukuhambisa uphawu lwesitebhisi 0123, gcwalisa imihlaba ngophindaphindo lwe 1E Kwi RX Ipateni yemenyu, umntu unokukhangela zonke iipatheni apho ubhaqo lwemposiso lunokwenzeka. Qaphela ukuba i-TX kunye ne-RX ipateni kufuneka ifane ukufumana i-RX lock kwaye ngenxa yoko ukwazi ukwenza imilinganiselo. Kwakhona ipateni 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. EksampI-le of tweaking izicwangciso zamehlo zangaphandle ziboniswe ngezantsi
Ukungagqibeki 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 engundoqo, 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. Eyona nto iphambili, itephu yangaphambili nasemva zisebenzisa amanani edijithali aphakathi kwe -1000 kunye +1000. Ukwandisa nokunciphisa iikhesa zangaphambili nasemva kuya kuchaphazela ampimfundo. Nceda uqinisekise ukuba isixa-mali sekhesa zangaphambili, zesithuba kunye neziziintloko ngu-≤ 1000 ukuze ube nokusebenza ngokupheleleyo. Ukuba inani leempompo lidlula i-1000, umgca wesignali we-TX awunakugcinwa.
Isiphumo se-cursor yangaphambili kwi-pulse
Isiphumo se-Post-cursor kwi-pulse
Umsebenzisi unokuhlela i-coefficient yeempompo ezi-7 endaweni yeetephu ezi-3 nje ngokucofa isethingi engaphezulu kwaye emva koko ujonge ibhokisi ye-7 tep.
Emva kokufaka useto, ulawulo lwempompo esixhenxe luya kufumaneka ukuze luhlelwe phantsi kwe 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. I-reflection canceller isebenzisa amandla amaninzi kodwa iluncedo kumajelo anzima aqulethe utshintsho lwe-impedanceUfakelo lwempazamo lwenziwa kwibhloko ngesiseko sebhloko. Ibhloko nganye inamasuntswana angama-64, yahlulwe yaba zii-MSB ezingama-32 kunye nee-LSB ezingama-32.
