ADI ADIN2111 Ethernet switch e tla ba ntho e ka sehloohong ea kenyelletso ea litaba tse latelang.Ka sengoloa sena, mohlophisi o tšepa hore motho e mong le e mong a ka ba le tsebo le kutloisiso ea boemo ba eona le tlhaiso-leseling.Lintlha ke tse latelang.
ADIN2111 ke matla a tlase, ho rarahana ho tlase, switch ea boema-kepe ba Ethernet e habeli e kopanyang 10BASE-T1L PHY le boema-kepe ba Serial Peripheral Interface (SPI).Sesebelisoa se sebelisa node e thibelang matla a tlase bakeng sa lits'ebetso tsa Industrial Ethernet mme e lumellana le IEEE® 802.3cg-2019™ Ethernet standard bakeng sa sebaka se selelele sa 10 Mbps Single Pair Ethernet (SPE).Phetoho (ho khaola kapa ho boloka le ho ea pele) e tšehetsa mekhoa e mengata ea li-cabling pakeng tsa likou tse peli tsa Ethernet le SPI host port, e fanang ka tharollo e feto-fetohang bakeng sa line, daisy-chain kapa ring network topology.
ADIN2111 e ts'ehetsa ho fihla ho limithara tse 1700 tsa cable ka tšebeliso ea matla a tlase haholo a 77 mW.Li-cores tse peli tsa PHY li ts'ehetsa ts'ebetso ea 1.0 V pp le 2.4 V pp joalo ka ha ho hlalositsoe maemong a IEEE 802.3cg 'me e ka tsamaisoa ho tsoa seporong se le seng sa 1.8 V kapa 3.3 V.ADIN2111 e fumaneha ka mokhoa o sa laoleheng moo sesebelisoa se fetisetsang sephethephethe pakeng tsa likou tse peli tsa Ethernet.
Sesebelisoa se kopanya switch, li-cores tse peli tsa Ethernet tsa 'mele (PHY) tse nang le li-interface tsa taolo ea phihlello ea mecha ea litaba (MAC), le lisebelisoa tsohle tse amanang le li-circuits tsa analog, lisebelisoa tsa ho kenya le ho hlahisa oache.Sesebelisoa se boetse se kenyelletsa mela ea ka hare ea li-buffer, SPI le li-subsystem registering, le taolo ea taolo ea ho laola reset le taolo ea oache le tlhophiso ea phini ea hardware.
ADIN2111 e kopanya potoloho ea ho lekola phepelo ea motlakase le potoloho ea matla a ho seta bocha (POR) bakeng sa ho matlafatsa boemo ba sistimi.SPI ea terata e 4 e sebelisoang ho buisana le moamoheli e ka hlophisoa e le OPEN Alliance SPI kapa Generic SPI.Mefuta ena ka bobeli e ts'ehetsa ts'ireletso ea data ea boikhethelo kapa Cyclic Redundancy Check (CRC).
