ADI ADIN2111 Ethernet mgba ọkụ ga-abụ isi ihe mmeghe nke ọdịnaya ndị a.Site na edemede a, onye nchịkọta akụkọ na-atụ anya na onye ọ bụla nwere ike inwe ụfọdụ ihe ọmụma na nghọta nke ọnọdụ ya na ozi metụtara ya.Nkọwa bụ ndị a.
ADIN2111 bụ ike dị ala, mgbagwoju anya dị ala, ngbanwe ọdụ ụgbọ mmiri Ethernet nke na-ejikọta 10BASE-T1L PHY na ọdụ ụgbọ mmiri Serial Peripheral Interface (SPI).Ngwaọrụ ahụ na-eji ọnụ mmachi ike dị ala maka ngwa Ethernet Industrial ma na-akwado ụkpụrụ IEEE® 802.3cg-2019™ Ethernet maka ogologo anya 10 Mbps Single Pair Ethernet (SPE).Mgbanwe ahụ (ịkpụcha ma ọ bụ ụlọ ahịa na-aga n'ihu) na-akwado ọtụtụ nhazi cabling n'etiti ọdụ ụgbọ mmiri Ethernet abụọ na ọdụ ụgbọ mmiri SPI, na-enye ihe ngwọta na-agbanwe maka ahịrị, daisy-chain ma ọ bụ mgbanaka netwọk topologies.
ADIN2111 na-akwado ihe ruru mita 1700 nke eriri eriri na ike ike dị ala nke 77 mW.Cores abụọ PHY na-akwado ọrụ 1.0 V pp na 2.4 V pp dị ka akọwara na ọkọlọtọ IEEE 802.3cg ma nwee ike ịkwado ya site na otu ụgbọ oloko ọkọnọ 1.8 V ma ọ bụ 3.3 V.ADIN2111 dị na nhazi enweghị njikwa ebe ngwaọrụ na-ebugharị okporo ụzọ na-akpaghị aka n'etiti ọdụ ụgbọ mmiri Ethernet abụọ.
Ngwa ahụ na-ejikọta mgba ọkụ, cores abụọ Ethernet physical Layer (PHY) nwere njikwa ohere mgbasa ozi (MAC), yana sekit analog niile metụtara, ntinye na ngwaọrụ nchekwa elekere.Ngwaọrụ ahụ gụnyekwara ahịrị n'ime, SPI na ndekọ subsystem, yana njikwa njikwa iji jikwaa ntọgharị na njikwa elekere yana nhazi ntụtụ ngwaike.
ADIN2111 na-ejikọta voltaji ọkọnọ nlekota circuitry na ike-na-reset (POR) circuitry maka mma usoro-larịị siri ike.Enwere ike ịhazi SPI 4-waya iji soro onye ọbịa na-ekwurịta okwu ka OPEN Alliance SPI ma ọ bụ Generic SPI.Ụdịdị abụọ a na-akwado nchedo data nhọrọ ma ọ bụ Nyochaa Redundancy Cyclic (CRC).
Enwere ike ịhazi PHY ọ bụla nke ADIN2111 ka ọ wepụta nkwụsị ngwaike mgbe nrụpụta ngwaike (RESET pin wedara ala) site na ịtọ CRSM_HRD_RST_IRQ_EN bit na Ndebanye aha nkpuchi nkpuchi PHY kwekọrọ (CRSM_IRQ_MASK).Agbanyeghị na enwere ike iji PHY abụọ ahụ wepụta nkwụsị ngwaike, PHY 1 ka akwadoro maka ebumnuche a.Mgbe onye isi SPI natachara nkwụsị ngwaike site na pin INT, a na-edozikwa PHYINT bit (otu n'otu, P2_PHYINT) dị na ndekọ ọkwa 0 (otu n'otu, ndekọ ọkwa 1) na 1, na-egosi nkwụsịtụ sitere na PHY 1 (otu n'otu, PHY). 2) .Enwere ike ịlele isi mmalite nkwụsịtụ ahụ site na iji CRSM_HRD_RST_IRQ_LH bit dị na Ndebanye aha nkwụsị System PHY kwekọrọ (CRSM_IRQ_STATUS).
Maka nkwenye sistemu site na iji njikwa nnabata mpụga, enwere ike ịrịọ PHY ọ bụla nke ADIN2111 ka ọ wepụta nkwụsị ngwaike na pin INT site na iji CRSM_SW_IRQ_REQ bit na Sistemụ Nkpuchi Mask Register (CRSM_IRQ_MASK).Agbanyeghị na enwere ike iji PHY abụọ ahụ wepụta nkwụsị ngwaike, PHY 1 ka akwadoro maka ebumnuche a.Mgbe onye isi SPI natachara nkwụsị ngwaike site na pin INT, a na-edobekwa PHYINT (otu n'otu, P2_PHYIN bit) dị na ndekọ ọkwa 0 (otu n'otu, ndekọ ọkwa 1) ka ọ bụrụ 1, na-egosi nkwụsịtụ sitere na PHY 1 (otu n'otu, PHY). 2) .Enwere ike ịlele isi mmalite nkwụsịtụ ahụ site na iji CRSM_SW_IRQ_LH bit na Ndebanye aha nkwụsị System PHY kwekọrọ (CRSM_IRQ_STATUS).
Onye ọ bụla ADIN2111 PHY nwekwara ike ịmepụta nkwụsịtụ njehie sistemụ.Ọkọlọtọ nkwụsịtụ ahụ dị na mpaghara ibe n'ibe echekwabara nke ndekọ ọnọdụ nkwụsịtụ sistemu PHY kwekọrọ (CRSM_IRQ_STATUS).Ekwesịrị ịhazi ndekọ nkpuchi nkpuchi sistemụ (CRSM_IRQ_MASK) na PHY kwekọrọ iji mee ka njehie sistemụ kwụsị.Lee Tebụl 212 maka nkọwa gbasara nkwụsịtụ nkpuchi.ADIN2111 ga-enwerịrị nrụgharị ngwaike iji nwetaghachi site na nkwụsị njehie sistemụ site na otu n'ime PHY abụọ ahụ (CRSM_IRQ_STATUS echekwara 1 na PHY dị iche iche).
