ADI ADIN2111 Ethernethloovyuav yog lub ntsiab lus taw qhia txog cov ntsiab lus hauv qab no. Los ntawm tsab xov xwm no, tus editor cia siab tias txhua tus tuaj yeem muaj qee qhov kev paub thiab kev nkag siab txog nws cov xwm txheej thiab cov ntaub ntawv. Cov ntsiab lus yog raws li nram no.
ADIN2111 yog lub zog qis, tsis tshua muaj kev nyuaj, dual Ethernet chaw nres nkojhloovuas ua ke nrog 10BASE-T1L PHY thiab Serial Peripheral Interface (SPI) chaw nres nkoj. Cov cuab yeej siv lub tshuab hluav taws xob uas tsis muaj zog rau cov ntawv thov muaj Ethernet thiab ua raws li IEEE® 802.3cg-2019™ Ethernet tus qauv rau kev ncua deb 10 Mbps Ib Pair Ethernet (SPE). Covhloov(txiav-dhau los yog khw-thiab-mus tom ntej) txhawb nqa ntau qhov kev teeb tsa cabling ntawm ob qhov chaw nres nkoj Ethernet thiab SPI tus tswv chaw nres nkoj, muab cov kev daws teeb meem yooj yim rau kab, daisy-chain lossis lub nplhaib network topologies.
ADIN2111 txhawb nqa txog li 1700 meters ntawm cable ncav cuag nrog ultra-tsawg zog noj ntawm 77 mW. Ob lub PHY cores txhawb nqa 1.0 V pp thiab 2.4 V pp kev ua haujlwm raws li tau hais tseg hauv IEEE 802.3cg tus qauv thiab tuaj yeem siv tau los ntawm ib qho 1.8 V lossis 3.3 V cov khoom siv rail. ADIN2111 muaj nyob rau hauv qhov kev teeb tsa tsis raug tswj xyuas qhov twg lub cuab yeej cia li xa mus los ntawm ob qhov chaw nres nkoj Ethernet.
Cov cuab yeej integrates ahloov, ob lub Ethernet lub cev txheej (PHY) cores nrog media access control (MAC) interfaces, thiab tag nrho cov kev cuam tshuam analog circuitry, input thiab output moos buffering li. Cov cuab yeej tseem suav nrog cov kab tsis nyob sab hauv, SPI thiab subsystem sau npe, thiab tswj cov logic los tswj kev pib dua thiab tswj moos thiab kho vajtse tus pin teeb tsa.
ADIN2111 integrates voltage supply monitoring circuitry and power-on-reset (POR) circuitry for improved system-level robustness. 4-xaim SPI siv los sib txuas lus nrog tus tswv tsev tuaj yeem teeb tsa raws li OPEN Alliance SPI lossis Generic SPI. Ob hom txhawb kev xaiv cov ntaub ntawv tiv thaiv lossis Cyclic Redundancy Check (CRC).
Txhua PHY ntawm ADIN2111 kuj tuaj yeem tsim kho kom tsim kho kho vajtse cuam tshuam tom qab kho vajtse pib dua (RESET tus pin rub qis) los ntawm kev teeb tsa CRSM_HRD_RST_IRQ_EN me ntsis hauv qhov sib thooj PHY's System Interrupt Mask Register (CRSM_IRQ_MASK). Txawm hais tias ob qho tib si PHYs tuaj yeem siv los tsim kho vajtse cuam tshuam, PHY 1 tau pom zoo rau lub hom phiaj no. Tom qab tus tswv SPI tau txais cov khoom siv cuam tshuam los ntawm INT tus pin, PHYINT ntsis (feem ntau, P2_PHYINT ntsis) ntawm cov xwm txheej sau npe 0 (raws li, raws li txoj cai sau npe 1) kuj tau teeb tsa rau 1, ceeb toom kev cuam tshuam los ntawm PHY 1 (feem ntau, PHY 2). Lub hauv paus ntawm kev cuam tshuam tuaj yeem raug kuaj xyuas siv CRSM_HRD_RST_IRQ_LH ntsis hauv PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).
Rau kev txheeb xyuas qhov system siv tus tswj hwm sab nraud, txhua PHY ntawm ADIN2111 tuaj yeem thov kom tsim kho kho vajtse cuam tshuam ntawm INT tus pin siv CRSM_SW_IRQ_REQ me ntsis hauv System Interrupt Mask Register (CRSM_IRQ_MASK). Txawm hais tias ob qho tib si PHYs tuaj yeem siv los tsim kho vajtse cuam tshuam, PHY 1 tau pom zoo rau lub hom phiaj no. Tom qab tus tswv SPI tau txais cov khoom siv cuam tshuam los ntawm INT tus pin, PHYINT ntsis (feem ntau, P2_PHYINT ntsis) hauv cov xwm txheej sau npe 0 (raws li, raws li txoj cai sau npe 1) kuj tau teeb tsa rau 1, ceeb toom kev cuam tshuam los ntawm PHY 1 (feem ntau, PHY 2). Lub hauv paus ntawm kev cuam tshuam tuaj yeem raug kuaj xyuas siv CRSM_SW_IRQ_LH ntsis hauv PHY's System Interrupt Status Register (CRSM_IRQ_STATUS).
Txhua ADIN2111 PHY tuaj yeem tsim kom muaj kev cuam tshuam kev cuam tshuam. Cov chij cuam tshuam yog nyob rau hauv cov khoom tshwj xeeb ntawm cov PHY's System Interrupt Status Register (CRSM_IRQ_STATUS). Lub kaw lus cuam tshuam daim npog qhov ncauj qhov ntswg (CRSM_IRQ_MASK) yuav tsum tau teeb tsa ntawm qhov sib txuas PHY txhawm rau txhawm rau txhim kho qhov teeb meem cuam tshuam. Saib Table 212 kom paub meej txog kev cuam tshuam daim npog qhov ncauj. ADIN2111 yuav tsum tau kho kho dua tshiab kom rov qab los ntawm qhov system yuam kev cuam tshuam los ntawm ib qho ntawm ob PHYs (CRSM_IRQ_STATUS tshwj tseg me ntsis nyeem 1 ntawm PHY).
ADIN2111 suav nrog cov khoom siv hluav taws xob saib xyuas hluav taws xob los xyuas kom meej tias cov nti muaj cov khoom siv hluav taws xob zoo ua ntej pib lub zog ua ntu zus. Thaum lub zog-up, ADIN2111 tseem nyob rau hauv lub xeev kho vajtse rov qab mus txog thaum txhua qhov khoom siv tshaj nws qhov tsawg kawg nkaus qhov pib thiab cov khoom siv tau pom zoo.
Ib qho kho vajtse rov pib dua yog pib los ntawm lub hwj chim rov pib dua Circuit Court lossis los ntawm kev tsav lub RESET tus pin qis rau tsawg kawg 10 µs. ADIN2111 suav nrog ib qho hluav taws xob deglitch ntawm tus pin no kom tsis lees txais cov pulses luv dua 1 µs. Thaum RESET tus pin yog deasserted, tag nrho cov input/output (I/O) pins tseem nyob rau hauv tri-xeev hom, cov kho vajtse configuration pins yog latched, thiab cov I/O pins yog configured rau lawv functional hom. Lub voj voog siv lead ua oscillator tau qhib thaum tag nrho cov khoom siv hluav taws xob sab nraud thiab sab hauv siv tau thiab ruaj khov. Tom qab siv lead ua pib thiab stabilizes, lub voj voog-xauv (PLL) tau qhib. Tom qab ncua sijhawm ntawm 90 ms (max) tom qab RESET tus pin yog deasserted, tag nrho cov moos sab hauv tau lees paub, lub logic sab hauv raug tso tawm los ntawm kev pib dua, thiab tag nrho cov SPI sab hauv, PHY 1 thiab PHY 2 cov ntawv sau npe tuaj yeem siv tau los ntawm SPI. Lub CLK25_REF moos tso zis yog tuav qis thaum RESET tus pin tau qis thiab tseem qis rau 70 ms (max) tom qab RESET tus pin tau qis.
Tag nrho cov ntsiab lus saum toj no yog tag nrho cov lus qhia coj los ntawm tus editor lub sijhawm no. Yog tias koj xav paub ntau ntxiv txog nws, koj tuaj yeem tshawb xyuas nws ntawm peb lub vev xaib lossis hauv Baidu thiab Google.
