ADI ADIN2111 Ethernetchinjachichava chikuru sumo chinhu chezvinotevera zvirimo. Kuburikidza nechinyorwa ichi, mupepeti anotarisira kuti munhu wese anogona kuve neruzivo uye kunzwisisa kwemamiriro ayo ane hukama uye ruzivo. Mashoko acho ndeaya anotevera.
Iyo ADIN2111 isimba rakaderera, rakaderera kuoma, hunyambiri Ethernet portchinjaiyo inobatanidza 10BASE-T1L PHY uye Serial Peripheral Interface (SPI) chiteshi. Chishandiso chinoshandisa yakaderera simba inomanikidzirwa node yeIndustrial Ethernet application uye inoenderana neIEEE® 802.3cg-2019™ Ethernet chiyero chedaro refu 10 Mbps Single Pair Ethernet (SPE). Thechinja(kucheka-kuburikidza kana chitoro-uye-mberi) inotsigira akawanda cabling masisitimu pakati peiyo mbiri Ethernet ports uye SPI host port, ichipa mhinduro inoshanduka yemutsara, daisy-chain kana mhete network topologies.
Iyo ADIN2111 inotsigira kusvika 1700 metres yetambo yekusvika ine Ultra-yakaderera simba rekushandisa 77 mW. Iwo maviri PHY cores anotsigira 1.0 V pp uye 2.4 V pp mashandiro sekutsanangurwa kwazvinoitwa muIEEE 802.3cg chiyero uye inogona kufambiswa kubva kune imwechete 1.8 V kana 3.3 V yekugovera njanji. Iyo ADIN2111 inowanikwa mune isingatarisirwe gadziriso apo mudziyo unoendesa otomatiki traffic pakati pezviteshi zviviri zveEthernet.
Chigadzirwa chacho chinobatanidza achinja, maviri Ethernet yemuviri layer (PHY) cores ine midhiya yekuwana control (MAC) interfaces, uye ese ane hukama analog wedunhu, yekupinza uye inobuda wachi inobhura michina. Chishandiso ichi chinosanganisirawo mitsetse yemukati buffer, SPI uye subsystem marejista, uye kudzora mantiki kubata reset uye wachi kutonga uye hardware pini kumisikidza.
Iyo ADIN2111 inosanganisa voltage yekutarisa yekutarisa dunhu uye simba-on-reset (POR) redunhu rekuvandudza sisitimu-nhanho kusimba. Iyo 4-waya SPI inoshandiswa kutaurirana nemugamuchiri inogona kugadzirwa seOPEN Alliance SPI kana Generic SPI. Ose mamodhi anotsigira sarudzo yekudzivirira data kana Cyclic Redundancy Check (CRC).
Imwe neimwe PHY yeADIN2111 inogonawo kugadzirwa kuti igadzire hardware kukanganisa mushure mekugadzirisa hardware (RESET pini yakadhonzwa pasi) nekuisa iyo CRSM_HRD_RST_IRQ_EN bit mune inoenderana PHY's System Interrupt Mask Register (CRSM_IRQ_MASK). Kunyangwe ese maPHY anogona kushandiswa kugadzira hardware kukanganisa, PHY 1 inokurudzirwa nekuda kweichi chinangwa. Mushure mekunge tenzi weSPI agamuchira kukanganiswa kwehardware kubva kuINT pini, iyo PHYINT bit (zvichitevedzana, iyo P2_PHYINT bit) pane chinzvimbo rejista 0 (zvichitevera, chimiro chekunyoresa 1) inoiswawo ku1, ichizivisa kukanganisa kubva kuPHY 1 (zvichitevera, PHY. 2) . Kwakabva kukanganiswa kunogona kutariswa uchishandisa CRSM_HRD_RST_IRQ_LH bit mune inoenderana PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).
Kuti uone masisitimu uchishandisa wekunze anotonga controller, PHY yega yega yeADIN2111 inogona kukumbirwa kuti iunze kukanganisa kwehardware paINT pin uchishandisa CRSM_SW_IRQ_REQ bit muSystem Interrupt Mask Register (CRSM_IRQ_MASK). Kunyangwe ese maPHY anogona kushandiswa kugadzira hardware kukanganisa, PHY 1 inokurudzirwa nekuda kweichi chinangwa. Mushure mekunge tenzi weSPI agamuchira kukanganiswa kwehardware kubva kuINT pini, iyo PHYINT bit (zvichitevera, iyo P2_PHYINT bit) mune chimiro rejista 0 (zvichitevera, chimiro chekunyoresa 1) inoiswawo ku1, ichizivisa kukanganisa kubva kuPHY 1 (zvichitevera, PHY. 2) . Kwakakanganisika kunogona kutariswa pachishandiswa CRSM_SW_IRQ_LH bit muPHY's System Interrupt Status Register (CRSM_IRQ_STATUS) inoenderana.
Imwe neimwe ADIN2111 PHY inogonawo kugadzira kukanganisa kwehurongwa. Mireza inovhiringika iri muchikamu chakachengeterwa mabits che PHY's System Interrupt Status Register (CRSM_IRQ_STATUS). Iyo system inovhiringidza mask register (CRSM_IRQ_MASK) inofanirwa kugadzirwa pane inoenderana PHY kuti ikwanise kukanganisa system kukanganisa. Ona Tafura 212 yeruzivo rwekukanganisa masking. Iyo ADIN2111 inofanirwa kuita reset yehardware kuti idzore kubva pakukanganisa kwehurongwa kubva kune imwe yeaviri maPHYs (iyo CRSM_IRQ_STATUS yakachengetwa bit inoverenga 1 pane iyo PHY).
Iyo ADIN2111 inosanganisira yemagetsi ekutarisa dunhu kuti ive nechokwadi chekuti chip ine chaiyo voltage rekupa isati yatanga kutevedzana kwemagetsi. Munguva yesimba-kumusoro, iyo ADIN2111 inoramba iri muhardware reset state kudzamara imwe neimwe inopihwa yadarika hushoma hwayo hwekukwira uye kupihwa kunoonekwa kwakanaka.
Hardware reset inotangwa neiyo simba-pakugadzirisa reseti kana nekutyaira iyo RESET pini yakaderera kweinenge gumi µs. Iyo ADIN2111 inosanganisira deglitch sekita papini iyi kuramba pulses mapfupi pane 1 µs. Kana iyo RESET pini yabviswa, mapini ese ekuisa / kubuda (I / O) anoramba ari mu-tri-state modhi, mapini ekugadzirisa hardware anosungirirwa, uye mapini eI / O anogadzirirwa kune yavo inoshanda maitiro. Iyo crystal oscillator wedunhu inogoneswa kana ese ekunze uye emukati magetsi emagetsi anoshanda uye akagadzikana. Mushure mekunge kristaro yatanga nekudzikama, chikamu-chakakiyiwa loop (PLL) inogoneswa. Mushure mekunonoka kwe90 ms (max) mushure mekunge pini yeRESET yabviswa, mawachi ese emukati anosimbiswa, pfungwa yemukati inoburitswa kubva pakugadzirisa, uye ese emukati SPI, PHY 1 uye PHY 2 rejista anowanikwa kubva kuSPI. Iko CLK25_REF clock output inobatwa yakaderera apo RESET pini inotorwa pasi uye inoramba yakaderera kune 70 ms (max) mushure mokunge RESET pin inotorwa pasi.
Zvese zviri pamusoro apa zvese sumo yakaunzwa nemupepeti panguva ino. Kana uchida kuziva zvakawanda nezvazvo, ungashuvira kuzviongorora pawebhusaiti yedu kana paBaidu neGoogle.
