ADI ADIN2111 Ethernet switch idzakhala chinthu choyambirira chazomwe zili pansipa.Kudzera m'nkhaniyi, mkonzi akuyembekeza kuti aliyense atha kukhala ndi chidziwitso ndikumvetsetsa momwe zinthu zilili komanso chidziwitso chake.Tsatanetsatane ndi motere.
ADIN2111 ndi otsika mphamvu, otsika zovuta, wapawiri Efaneti doko lophimba kuti integrates 10BASE-T1L PHY ndi doko seri Peripheral Interface (SPI).Chipangizochi chimagwiritsa ntchito node yocheperako yamagetsi pamapulogalamu a Industrial Ethernet ndipo imagwirizana ndi IEEE® 802.3cg-2019™ Ethernet muyezo wamtunda wautali wa 10 Mbps Single Pair Ethernet (SPE).Kusinthana (kudula-kudutsa kapena sitolo-ndi-kutsogolo) kumathandizira masinthidwe angapo a cabling pakati pa madoko awiri a Ethernet ndi doko la SPI, kupereka yankho losinthika la mzere, daisy-chain kapena ring network topology.
ADIN2111 imathandizira mpaka 1700 metres ya chingwe chofikira ndi mphamvu yotsika kwambiri ya 77 mW.Ma cores awiri a PHY amathandizira 1.0 V pp ndi 2.4 V pp pp monga momwe amafotokozera muyeso wa IEEE 802.3cg ndipo amatha kuyendetsedwa kuchokera panjanji imodzi yokha ya 1.8 V kapena 3.3 V.ADIN2111 imapezeka mu kasinthidwe kosayendetsedwa komwe chipangizochi chimangotumiza magalimoto pakati pa madoko awiri a Efaneti.
Chipangizocho chimaphatikiza chosinthira, ma cores awiri a Ethernet (PHY) okhala ndi zolumikizira zolumikizira media (MAC), ndi zida zonse zogwirizana ndi analogi, zida zolowetsa ndi zotulutsa zotulutsa mawotchi.Chipangizochi chimaphatikizanso mizere yamkati, ma SPI ndi ma registry a subsystem, ndi malingaliro owongolera kuti azitha kukonzanso ndikuwongolera mawotchi ndi kasinthidwe ka pini ya hardware.
ADIN2111 imaphatikiza mayendedwe owunikira magetsi ndi magetsi-on-reset (POR) kuti apititse patsogolo kulimba kwadongosolo.4-waya SPI yomwe imagwiritsidwa ntchito polankhulana ndi wolandirayo ikhoza kusinthidwa kukhala OPEN Alliance SPI kapena Generic SPI.Mitundu yonse iwiri imathandizira chitetezo cha data kapena Cyclic Redundancy Check (CRC).
PHY iliyonse ya ADIN2111 ikhoza kukonzedwanso kuti ipangitse kusokoneza kwa hardware pambuyo pa kukonzanso kwa hardware (RESET pin kutsika pansi) pokhazikitsa CRSM_HRD_RST_IRQ_EN bit mu PHY's System Interrupt Mask Register (CRSM_IRQ_MASK).Ngakhale ma PHY onse atha kugwiritsidwa ntchito kupanga kusokoneza kwa hardware, PHY 1 ndiyovomerezeka pa izi.Mbuye wa SPI atalandira kusokonezedwa kwa hardware kuchokera ku pini ya INT, PHYINT bit (motsatira, P2_PHYINT bit) pa kaundula 0 (motsatira, kaundula wa 1) imayikidwanso ku 1, kudziwitsa kusokoneza kuchokera ku PHY 1 (motsatira, PHY). 2) .Komwe kusokoneza kungathe kufufuzidwa pogwiritsa ntchito CRSM_HRD_RST_IRQ_LH bit mu PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).
Kuti mutsimikizire makina pogwiritsa ntchito chowongolera chakunja, PHY iliyonse ya ADIN2111 ikhoza kufunsidwa kuti ipangitse kusokoneza kwa hardware pa INT pin pogwiritsa ntchito CRSM_SW_IRQ_REQ bit mu System Interrupt Mask Register (CRSM_IRQ_MASK).Ngakhale ma PHY onse atha kugwiritsidwa ntchito kupanga zosokoneza za hardware, PHY 1 ndiyovomerezeka pa izi.Mbuye wa SPI atalandira kusokoneza kwa hardware kuchokera ku INT pin, PHYINT bit (motsatira, P2_PHYINT bit) mu kaundula wa 0 (motsatira, kaundula wa 1) imayikidwanso ku 1, kudziwitsa kusokoneza kuchokera ku PHY 1 (motsatira, PHY). 2) .Komwe kusokonezako kutha kufufuzidwa pogwiritsa ntchito CRSM_SW_IRQ_LH bit mu kaundula wa PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).
Iliyonse ya ADIN2111 PHY imathanso kupanga kusokoneza kwadongosolo.Mbendera zosokoneza zili mugawo losungika la PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).Register yosokoneza chigoba cha makina (CRSM_IRQ_MASK) iyenera kukonzedwa pa PHY yofananira kuti izi zitheke kusokoneza zolakwika.Onani Table 212 kuti mudziwe zambiri za kusokoneza masking.ADIN2111 iyenera kukonzanso hardware kuti ibwererenso ku vuto la dongosolo kuchokera ku imodzi mwa ma PHY awiriwa (CRSM_IRQ_STATUS yosungidwayo imawerengedwa 1 pa PHY).
ADIN2111 imaphatikizapo dera loyang'anira magetsi kuti zitsimikizire kuti chip chili ndi magetsi oyenera asanayambe kutsatizana.Panthawi yamagetsi, ADIN2111 imakhalabe mumtundu wobwezeretsanso hardware mpaka chopereka chilichonse chidutsa malire ake okwera kwambiri ndipo kuperekedwa kumaonedwa kuti ndi kwabwino.
Kukhazikitsanso kwa hardware kumayambika ndi mphamvu yobwezeretsanso dera kapena kuyendetsa pini ya RESET yotsika kwa osachepera 10 µs.ADIN2111 imaphatikizapo kuzungulira kwa deglitch pa pini iyi kukana kugunda kwafupipafupi kuposa 1 µs.Pini ya RESET ikachotsedwa, zikhomo zonse zolowera / zotulutsa (I / O) zimakhalabe mumtundu wa tri-state, mapini opangira zida amakhomedwa, ndipo mapini a I / O amakonzedwa kuti azigwira ntchito.Dongosolo la crystal oscillator limathandizidwa pamene mphamvu zonse zakunja ndi zamkati zili zovomerezeka komanso zokhazikika.Pambuyo kristalo ayamba ndi kukhazikika, ndi gawo-lokhoma loop (PLL) ndiwolola.Pambuyo pa kuchedwa kwa 90 ms (max) pini ya RESET itachotsedwa, mawotchi onse amkati amatsimikiziridwa, malingaliro amkati amamasulidwa kuchokera kukonzanso, ndipo zolembera zonse zamkati za SPI, PHY 1 ndi PHY 2 zimapezeka kuchokera ku SPI.Kutulutsa kwa wotchi ya CLK25_REF kumakhala kotsika pamene pini ya RESET imatengedwa pansi ndipo imakhalabe yotsika kwa 70 ms (max) pambuyo poti pini ya RESET yatsitsidwa.
Zonse zomwe zili pamwambazi ndizomwe zabweretsedwa ndi mkonzi nthawi ino.Ngati mukufuna kudziwa zambiri za izi, mutha kuzifufuza patsamba lathu kapena pa Baidu ndi Google.
