    Incazelo

    Ama-transceivers e-HDV`s SFP24-(G)T Copper Small Form Pluggable (SFP) anokusebenza okuphezulu, imojula engabizi kakhulu ithobelana ne-Gigabit Ethernet kanye namazinga angu-1000- BASE-T njengoba kucaciswe ku-IEEE 802. 3-2002 kanye ne-IEEE 802.3ab, esekela i-1000Mbps yedatha- isilinganiso esingafika kumamitha ayi-100 sifinyelela phezu kwekhebuli yesigaba sesi-5 esingavikelekile. Imojula isekela izixhumanisi zedatha eziyi-duplex eziyi-1000 ezigcwele ezinamasiginali we-5-level Pulse Amplitude Modulation (PAM). Wonke amapheya amane kukhebula asetshenziswa ngesilinganiso sophawu ku-250Mbps kubhangqa ngayinye. Imojula inikeza ulwazi olujwayelekile lwe-serial ID oluhambisana ne-SFP MSA, olungafinyelelwa ngekheli lika-A0h nge-2wire serial protocol ye-CMOS EEPROM. I-IC ebonakalayo ingafinyelelwa ngebhasi le-2wire serial ekhelini elithi A0h.

    Amanothi:

    I-Plug Seq.: Phina ukulandelana kokuzibandakanya ngesikhathi sokuxhuma okushisayo.

    1) I-TX Fault iwukukhipha komqoqi ovulekile, okufanele kudonswe nge-resistor engu-4.7k~10kΩ ebhodini lomsingathi ukuya ku-voltage ephakathi kuka-2.0V ne-Vcc+0.3V. I-Logic 0 ibonisa ukusebenza okuvamile; I-logic 1 ibonisa iphutha le-laser lohlobo oluthile. Esimeni esiphansi, okukhiphayo kuzodonselwa ngaphansi kuka-0.8V.

    2) I-TX Khubaza okokufaka okusetshenziselwa ukuvala ukuphuma kwe-transmitter optical. Idonselwa phezulu ngaphakathi kwemojuli nge-resistor engu-4.7 ¨C 10 K. Izimo zayo yilezi:

    Phansi (0 ukuya ku-0.8V): I-Transmitter ivuliwe

    (>0.8, < 2.0V): Akuchazwanga

    Phezulu (2.0 kuya ku-3.465V): I-Transmitter Ikhubazekile

    Vula: I-Transmitter Ikhutshaziwe

    3) I-Mod-Def 0,1,2. Lawa amaphinikhodi encazelo yemojuli. Kufanele zidonswe nge-4.7K kuya ku-10K resistor ebhodini lomsingathi. I-voltage yokudonsa izoba yi-VccT noma i-VccR

    I-Mod-Def 0 isekelwe yimojuli ukukhombisa ukuthi imojuli ikhona

    I-Mod-Def 1 iwumugqa wewashi we-serial interface yezintambo ezimbili ze-serial ID

    I-Mod-Def 2 iwumugqa wedatha we-serial interface yezintambo ezimbili ze-serial ID

    I-4) I-LOS (Ukulahlekelwa Kwesiginali) ingumqoqi ovulekile / okukhipha amanzi, okumele kudonswe nge-4.7K kuya ku-10K resistor. Khuphula i-voltage phakathi kuka-2.0V ne-VccT, R+0.3V. Uma kuphezulu, lokhu okukhiphayo kubonisa ukuthi amandla okubona atholiwe angaphansi kokuzwela umamukeli wesimo esibi kakhulu (njengoba kuchazwe izinga elisetshenziswayo). Okuphansi kubonisa ukusebenza okuvamile. Esimeni esiphansi, okukhiphayo kuzodonselwa ku-<0.8V.

    5) I-RD-/+: Lena imiphumela yomamukeli ohlukile. Ziyi-AC ehlanganiswe nemigqa ehlukene eyi-100 okufanele iqedwe ngo-100 (umehluko) kumsebenzisi ongu-SERDES.

    6) TD-/+: Lawa ama-transmitter ahlukile. Ziyi-AC-coupled, imigqa ehlukile ene-100 yokuqedwa okuhlukile ngaphakathi kwemojuli.

    I-SFP24-(G)T inobubanzi be-voltage yokufaka engu-+5V +/- 5%. I-voltage ephezulu engu-3.3V ayivunyelwe ekusebenzeni okuqhubekayo.
