I-ADI ADIN2111 switch ye-Ethernet iya kuba yinto ephambili yokungeniswa komxholo olandelayo.Ngeli nqaku, umhleli unethemba lokuba wonke umntu unokuba nolwazi oluthile kunye nokuqonda imeko kunye nolwazi olunxulumeneyo.Iinkcukacha zimi ngolu hlobo lulandelayo.
I-ADIN2111 inamandla aphantsi, ukuntsonkotha okuphantsi, ukutshintshela kwe-Ethernet ezimbini ezidibanisa i-10BASE-T1L PHY kunye ne-Serial Peripheral Interface (SPI) port.Isixhobo sisebenzisa i-node ephantsi yokunciphisa amandla kwi-Industrial Ethernet izicelo kwaye ihambelana ne-IEEE® 802.3cg-2019™ Ethernet umgangatho we-Ethernet umgama omde we-10 Mbps Single Pair Ethernet (SPE).Umtshintshi (ukunqunyulwa okanye ukugcina-kunye-phambili) isekela ulungelelwaniso oluninzi lwe-cabling phakathi kwamachweba amabini e-Ethernet kunye ne-SPI host port, ebonelela ngesisombululo esiguquguqukayo somgca, i-daisy-chain okanye i-topology yenethiwekhi ye-ring.
I-ADIN2111 ixhasa ukuya kuthi ga kwi-1700 yeemitha zokufikelela kwintambo kunye nokusetyenziswa kwamandla aphantsi kwe-77 mW.Iimbilini ze-PHY cores zixhasa i-1.0 V pp kunye ne-2.4 V pp yokusebenza njengoko kuchazwe kumgangatho we-IEEE 802.3cg kwaye inokunikwa amandla ukusuka kwi-1.8 V okanye i-3.3 V yesitimela yokubonelela.I-ADIN2111 ifumaneka kuqwalaselo olungalawulwayo apho isixhobo sithumela ngokuzenzekelayo i-traffic phakathi kwamazibuko amabini e-Ethernet.
Isixhobo sidibanisa utshintshi, ii-Ethernet ezimbini zomaleko womzimba (PHY) kunye nolawulo lokufikelela kwimidiya (i-MAC) ujongano, kunye nazo zonke iisekethe ze-analog ezihambelanayo, igalelo kunye ne-output clock buffering devices.Isixhobo sikwabandakanya imigca ye-buffer yangaphakathi, i-SPI kunye neerejista ze-subsystem, kunye nengqiqo yokulawula ukulawula ukusetha kwakhona kunye nolawulo lwewotshi kunye noqwalaselo lwe-hardware pin.
I-ADIN2111 idibanisa i-voltage monitoring circuitry kunye ne-power-on-reset (POR) yesekethe yokuphucula ukomelela kwenqanaba lenkqubo.I-4-ingcingo ye-SPI esetyenziselwa ukunxibelelana nomninimzi inokuqwalaselwa njenge-OPEN Alliance SPI okanye i-Generic SPI.Zombini iindlela zixhasa ukhuseleko lwedatha olukhethwayo okanye iCyclic Redundancy Check (CRC).
I-PHY nganye ye-ADIN2111 ingaqwalaselwa ukuba ivelise uphazamiseko lwehardware emva kokusetha ngokutsha kwehardware (RESET pin yatsalwa phantsi) ngokucwangcisa i-CRSM_HRD_RST_IRQ_EN bit kwi-PHY ehambelanayo yeNkqubo yokuBhalisa iMask ehambelanayo (CRSM_IRQ_MASK).Nangona zombini ii-PHYs zingasetyenziselwa ukuvelisa ukuphazamiseka kwehardware, i-PHY 1 iyacetyiswa ngale njongo.Emva kokuba inkosi ye-SPI ifumana ukuphazamiseka kwe-hardware kwi-INT pin, i-PHYINT bit (ngokulandelelanayo, i-P2_PHYINT bit) kwirejista yesimo 0 (ngokulandelelanayo, irejista yesimo 1) nayo imiselwe kwi-1, ikwazisa ukuphazamiseka kwi-PHY 1 (ngokulandelelana, i-PHY). 2) .Umthombo wophazamiseko unokujongwa kusetyenziswa i-CRSM_HRD_RST_IRQ_LH bit kwi-PHY's ehambelanayo yeRejista yeSimo soNgxaki weNkqubo (CRSM_IRQ_STATUS).
Ukuqinisekiswa kwenkqubo kusetyenziswa umlawuli womkhosi wangaphandle, i-PHY nganye ye-ADIN2111 inokucelwa ukuba yenze uphazamiseko lwehardware kwi-INT pin usebenzisa i-CRSM_SW_IRQ_REQ bit kwi-System Interrupt Mask Register (CRSM_IRQ_MASK).Nangona zombini ii-PHYs zingasetyenziselwa ukuvelisa ukuphazamiseka kwehardware, i-PHY 1 iyacetyiswa ngale njongo.Emva kokuba inkosi ye-SPI ifumana ukuphazamiseka kwe-hardware kwi-INT pin, i-PHYINT bit (ngokulandelelanayo, i-P2_PHYINT bit) kwirejista yesimo 0 (ngokulandelelana, irejista yesimo 1) nayo imiselwe kwi-1, ikwazisa ukuphazamiseka kwi-PHY 1 (ngokulandelelanayo, i-PHY). 2) .Umthombo wophazamiseko unokutshekishwa kusetyenziswa i-CRSM_SW_IRQ_LH bit kwi-PHY ehambelanayo yeSimo sokuBhalisa sesiGaba sokuPhakamisa (CRSM_IRQ_STATUS).
Nganye i-ADIN2111 PHY inokuvelisa impazamo yenkqubo yokuphazamisa.Iiflegi zokuphazamiseka zibekwe kwicandelo leebhithi ezibekelwe i-PHY ehambelanayo yeSimo sokuBhalisa seSimo soNgxaki weNkqubo (CRSM_IRQ_STATUS).Inkqubo yokuphazamiseka kwerejista yemaski (CRSM_IRQ_MASK) kufuneka iqwalaselwe kwi-PHY ehambelanayo ukwenza impazamo yesixokelelwano isebenze.Jonga kwiTheyibhile 212 ngeenkcukacha malunga nokuphazamiseka kokufihla ubuso.I-ADIN2111 kufuneka iphinde iphinde iphinde ibuyele kwimpazamo yenkqubo ukusuka kwenye yee-PHY ezimbini (i-CRSM_IRQ_STATUS ibikelwe bit efundeka ngo-1 kwi-PHY ngokufanelekileyo).
I-ADIN2111 ibandakanya isiphaluka sokujonga umbane ukuqinisekisa ukuba i-chip ine-voltage efanelekileyo ngaphambi kokuba iqalise ukulandelelana kombane.Ngethuba lokunyuka kwamandla, i-ADIN2111 ihlala kwindawo yokusetha kwakhona i-hardware de unikezelo ngalunye lugqithise umgangatho walo wokunyuka kwaye unikezelo lubhekwa njengento enhle.
Ukusetha ngokutsha kwehardware kuqalwa ngamandla-onke ukuseta ngokutsha isekethe okanye ngokuqhuba i-RESET isikhonkwane esisezantsi noko i-10 µs.I-ADIN2111 ibandakanya isekethe ye-deglitch kule pin ukwala iipulses ezimfutshane kuno-1 µs.Xa i-RESET pin ihlanjululwa, zonke i-input/output (I/O) izikhonkwane zihlala kwimowudi ye-tri-state, i-hardware yoqwalaselo izikhonkwane zifakwe, kwaye i-I / O izikhonkwane ziqwalaselwe kwindlela yazo yokusebenza.I-crystal oscillator circuit inikwe amandla xa zonke izixhobo zamandla zangaphandle kunye zangaphakathi zivumelekile kwaye zizinzile.Emva kokuba i-crystal iqale kwaye izinzile, i-loop-locked loop (PLL) inikwe amandla.Emva kokulibaziseka kwe-90 ms (max) emva kokuba ipini ye-RESET ihlanjululwe, zonke iiwotshi zangaphakathi ziqinisekisiwe, i-logic yangaphakathi ikhutshwe ekusetyenzisweni kwakhona, kwaye zonke iirejista ze-SPI zangaphakathi, i-PHY 1 kunye ne-PHY 2 zifumaneka kwi-SPI.I-CLK25_REF i-clock output ibanjwe ephantsi xa i-RESET pin ithathwa iphantsi kwaye ihlala iphantsi kwi-70 ms (max) emva kokuba i-RESET pin ithathwa phantsi.
Wonke lo mxholo ungasentla uyintshayelelo eziswe ngumhleli ngeli xesha.Ukuba ufuna ukwazi ngakumbi ngayo, unganqwenela ukuyiphonononga kwiwebhusayithi yethu okanye kwiBaidu nakuGoogle.
