ADI ADIN2111 Ethernethindurabizaba intego nyamukuru yo gutangiza ibintu bikurikira. Binyuze muriyi ngingo, umwanditsi yizera ko buriwese ashobora kugira ubumenyi no gusobanukirwa kubyerekeranye namakuru. Ibisobanuro ni nkibi bikurikira.
ADIN2111 nimbaraga nke, zigoye, icyambu cya Ethernet ebyirihinduraihuza 10BASE-T1L PHY hamwe na Serial Peripheral Interface (SPI). Igikoresho gikoresha ingufu nkeya zidafite imbaraga kuri porogaramu ya Ethernet yinganda kandi yujuje IEEE® 802.3cg-2019 standard Igipimo cya Ethernet intera ndende 10 Mbps imwe imwe ya Ethernet (SPE). Uwitekahindura.
ADIN2111 ishyigikira metero zigera kuri 1700 z'umugozi zigera hamwe na ultra-low power ikoresha 77 mW. Ibice bibiri bya PHY bishyigikira imikorere ya 1.0 V pp na 2.4 V pp nkuko byasobanuwe mubipimo bya IEEE 802.3cg kandi birashobora gukoreshwa na gari ya moshi imwe 1.8 V cyangwa 3.3 V. ADIN2111 iraboneka muburyo butagenzuwe aho igikoresho gihita cyohereza traffic hagati yicyambu cya Ethernet.
Igikoresho gihuza ahindura, ibice bibiri bya Ethernet yumubiri (PHY) yibanze hamwe nigenzura ryibitangazamakuru (MAC), hamwe nibindi byose bifitanye isano na sisitemu yo kugereranya, kwinjiza no gusohora ibikoresho byerekana amasaha. Igikoresho kirimo kandi umurongo w'imbere imbere, SPI na rejisitiri ya sisitemu, hamwe no kugenzura logique yo gucunga reset no kugenzura amasaha hamwe nibikoresho bya pin.
ADIN2111 ihuza amashanyarazi yo kugenzura amashanyarazi no gukwirakwiza amashanyarazi (POR) kugirango urusheho gukomera kurwego rwa sisitemu. 4-wire SPI ikoreshwa mugushyikirana nuwakiriye irashobora gushyirwaho nka OPEN Alliance SPI cyangwa SPI rusange. Ubwo buryo bwombi bushigikira kurinda amakuru kubushake cyangwa Kugenzura Kugabanuka (CRC).
Buri PHY ya ADIN2111 irashobora kandi gushyirwaho kugirango habeho guhagarika ibyuma nyuma yo gusubiramo ibyuma (RESET pin yakuye hasi) mugushiraho biti bya CRSM_HRD_RST_IRQ_EN bitondekanya muri sisitemu ya PHY ya sisitemu yo guhagarika Mask (CRSM_IRQ_MASK). Nubwo PHYs zombi zishobora gukoreshwa kugirango habeho guhagarika ibyuma, PHY 1 irasabwa kubwiyi ntego. Nyuma yuko umuyobozi wa SPI yakiriye ibyuma byahagaritswe kuva muri INT pin, biti ya PHYINT (bikurikiranye, biti ya P2_PHYINT) kurutonde rwimiterere 0 (uko bikurikirana, kwiyandikisha kumiterere 1) nayo yashyizwe kuri 1, imenyesha guhagarika kuva kuri PHY 1 (uko bikurikirana, PHY 2). Inkomoko yo guhagarika irashobora kugenzurwa ukoresheje CRSM_HRD_RST_IRQ_LH biti mubitabo bihuye na PHY ya sisitemu yo guhagarika imiterere (CRSM_IRQ_STATUS).
Kugenzura sisitemu ukoresheje umugenzuzi wo hanze, buri PHY ya ADIN2111 irashobora gusabwa kubyara ibyuma byahagaritswe kuri pin ya INT ukoresheje CRSM_SW_IRQ_REQ biti muri sisitemu yo guhagarika Mask (CRSM_IRQ_MASK). Nubwo PHYs zombi zishobora gukoreshwa kugirango habeho guhagarika ibyuma, PHY 1 irasabwa kubwiyi ntego. Nyuma yuko umuyobozi wa SPI yakiriye ibyuma byahagaritswe kuva INT pin, biti ya PHYINT (bikurikiranye, biti ya P2_PHYINT) mubitabo byimiterere 0 (uko bikurikirana, kwiyandikisha kumiterere 1) nayo yashyizwe kuri 1, imenyesha guhagarika kuva kuri PHY 1 (bikurikiranye, PHY 2). Inkomoko yo guhagarika irashobora kugenzurwa ukoresheje CRSM_SW_IRQ_LH biti mubitabo bihuye na PHY ya sisitemu yo guhagarika imiterere (CRSM_IRQ_STATUS).
Buri ADIN2111 PHY irashobora kandi kubyara sisitemu ikosa. Ibendera ryahagaritswe riri mubice byabitswe byabigenewe bya sisitemu ya PHY ya sisitemu yo guhagarika imiterere (CRSM_IRQ_STATUS). Sisitemu yo guhagarika mask yandikwa (CRSM_IRQ_MASK) igomba gushyirwaho kuri PHY ijyanye kugirango sisitemu ihagarike. Reba Imbonerahamwe 212 kugirango ubone ibisobanuro birambuye kubihagarika. ADIN2111 igomba gusubiramo ibyuma kugirango igarure ikosa rya sisitemu ihagaritswe muri imwe muri PHYs ebyiri (CRSM_IRQ_STATUS yabitswe bito isoma 1 kuri PHY bijyanye).
ADIN2111 ikubiyemo imiyoboro yo kugenzura amashanyarazi kugirango tumenye neza ko chip ifite amashanyarazi akwiye mbere yo gutangiza amashanyarazi. Mugihe cyo kongera ingufu, ADIN2111 iguma muburyo bwo gusubiramo ibyuma kugeza igihe itangwa rirenze igipimo ntarengwa cyo kuzamuka kandi itangwa nkibyiza.
Gusubiramo ibyuma bitangizwa na power-on reset circuit cyangwa mugutwara RESET pin hasi byibuze 10 µs. ADIN2111 ikubiyemo umuzenguruko wa deglitch kuriyi pin kugirango wange impiswi ngufi kurenza 1 µs. Iyo pin ya RESET yasohotse, pin zose zinjiza / zisohoka (I / O) ziguma muburyo bwa tri-leta, ibyuma byabugenewe byapanze, kandi I / O byashyizwe muburyo bukora. Inzira ya kristu oscillator ishoboka iyo ibikoresho byose byo hanze ninyuma byemewe kandi bihamye. Nyuma ya kristu itangiye kandi igahagarara, icyiciro gifunze loop (PLL) irashoboka. Nyuma yo gutinda kwa ms 90 (max) nyuma yo gusubizwa pin ya RESET, amasaha yose yimbere arashimangirwa, logique yimbere irekurwa gusubiramo, kandi SPI yimbere, PHY 1 na PHY 2 byandikwa kuri SPI. Isaha ya CLK25_REF isohoka hasi iyo pin ya RESET ifashwe hasi kandi igakomeza kuba hasi kuri ms 70 (max) nyuma yuko pin ya RESET ifashwe hasi.
Ibirimo byose byavuzwe haruguru nibisobanuro byose byazanywe nuwanditse iki gihe. Niba ushaka kumenya byinshi kubyerekeye, urashobora kubishakisha kurubuga rwacu cyangwa kuri Baidu na Google.
