Incazelo:

I-JHA3401 10/100/1000BASE-T i-transceiver yethusi ye-SFP isebenza kahle, imojula engabizi kakhulu ithobelana ne-Gigabit Ethernet kanye namazinga angu-10/100/1000BASE-T njengoba kucaciswe ku-IEEE 802. 3-2002 kanye ne-IEEE 802.310/00 100/1000Mbps idatha- isilinganiso esingafika kumamitha angu-100 sifinyelela phezu kwekhebula engavikelekile yesigaba sesi-5 esisontekile. I-JHA3401 isekela izixhumanisi zedatha eziyi-10/100/1000 Mbps ezigcwele ezinamasiginali we-5-level Pulse Amplitude Modula-tion (PAM). Wonke amapheya amane kukhebula asetshenziswa ngesilinganiso sophawu ku-250Mbps kubhangqa ngayinye. I-JHA3401 inikeza ulwazi olujwayelekile lwe-serial ID oluthobelana ne-SFP MSA, olungafinyelelwa ngekheli elithi A0h nge-2-wire serial yephrothokholi ye-CMOS EEPROM. I-IC ebonakalayo ingafinyelelwa ngebhasi elinezintambo ezingu-2 ekhelini elithi ACh.

•I-SFP ukuze Ibambe Isixhumi Pin Out

Amanothi:

1. I-TX Fault ayisetshenziswa futhi ihlale iboshelwe phansi nge-resistor engu-100 ohm.

2. I-TX Ukukhubaza njengoba kuchazwe ku-MSA akusebenzi kumojula ye-1000BASE-T, kodwa isetshenziselwa ukwenza lula njengokufaka ukusetha kabusha i-ASIC yangaphakathi. Le phinikhodi idonselwa phezulu ngaphakathi kwemojuli ene-resistor engu-4.7 KW.

Phansi (0 – 0.8 V): I-Transceiver ivuliwe

Phakathi kuka-(0.8 V kanye no-2.0 V): Akuchazwanga

Phezulu (2.0 – 3.465 V): I-Transceiver isesimweni sokusetha kabusha

Vula: I-Transceiver isesimweni sokusetha kabusha

3. Mod-Def 0,1,2. Lawa amaphinikhodi encazelo yemojuli. Kufanele zidonswe nge-resistor engu-4.7-10 KW ebhodini lomsingathi ukuze zihanjiswe ngaphansi kwe-VCCT + 0.3 V noma i-VCCR + 0.3 V.

I-Mod Def 0 iboshelwe phansi nge-resistor engu-100 ohm ukukhombisa ukuthi imojuli ikhona.

I-Mod-Def 1 iwumugqa wewashi we-serial interface yezintambo ezimbili ku-ID ye-serial ongayikhetha

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

4. I-LVTTL ihambisana ne-voltage enkulu engu-2.5V. Ayisekelwe ku-HTSFP-24-111X

5. I-RD-/+: Lena imiphumela yokwamukela okuhlukile. Ziyi-ac ehambisana nemigqa ehlukile engu-100 ohm okufanele iqedwe ngomehluko we-100 ohm ku-SerDes yomsebenzisi. I-ac coupling yenziwa ngaphakathi kwemojuli futhi ngaleyo ndlela ayidingeki ebhodini lomsingathi. Ukushintshashintsha kwamandla kagesi kule migqa kuzoba phakathi kuka-370 no-2000 mV umehluko (185 – 1000 mV single iqedwe) uma iqedwa kahle. Lawa mazinga ahambisana nokushintshashintsha kwamandla kagesi e-CML kanye ne-LVPECL.

6. I-VCCR kanye ne-VCCT yizinto ezinikezwa amandla ezitholayo nezidlulisa amandla. Achazwa ngokuthi 3.3 V ± 5% kuphinikhodi yesixhumi se-SFP. Umthamo omkhulu wamanje wokunikezwa cishe u-300mA futhi wamanje wokushesha ohambisanayo ngeke ube ngaphezu kuka-30 mA ngaphezu kwesimo sokuzinza ngemva kwama-nanoseconds angu-500.

7. TD-/+: Lawa ama-transmitter ahlukene. Bayimigqa ehlukene ehlanganiswe nge-ac ene-100 W yokuhlukanisa umehluko ngaphakathi kwemojuli. I-ac coupling yenziwa ngaphakathi kwemojuli futhi ngaleyo ndlela ayidingeki ebhodini lomsingathi. Okokufaka kuzokwamukela ukushintsha okuhlukile okungu-500 – 2400 mV (250 –1200 mV single ephelile), nakuba kunconywa ukuthi amanani aphakathi kuka-500 no-1200 mV umehluko (okuphele ngo-250 – 600 mV okukodwa) asetshenziselwe ukusebenza okungcono kakhulu kwe-EMI. Lawa mazinga ahambisana nokushintshashintsha kwamandla kagesi e-CML kanye ne-LVPECL.

Umdwebo wezinombolo zephinikhodi yesixhumi sebhodi lomsingathi namagama

•+3.3V Volt Electrical Power Interface

I-JHA3401 inobubanzi be-voltage yokufaka engu-3.3 V +/- 5%. I-voltage engu-4 V ephezulu ayivunyelwe ekusebenzeni okuqhubekayo.

Isexwayiso: Ukusetshenziswa kwamandla namandla okwandayo kuphezulu kunamanani ashiwo ku-SFP MSA

•Izimpawu Zejubane Eliphansi

I-MOD_DEF(1) (SCL) ne-MOD_DEF(2) (SDA), amasiginali we-CMOS wokudonsa amanzi avulekile. Kokubili i-MOD_ DEF(1) kanye ne-MOD_DEF(2) kumelwe idonselwe phezulu ukuze ihost_Vcc.

•Isixhumi esibonakalayo sikagesi esinesivinini esikhulu

Wonke amasignali anesivinini esiphezulu ahlanganiswe ne-AC ngaphakathi.
