Ibisobanuro:

JHA3401 10/100 / 1000BASE-T umuringa wa SFP transceiver ni imikorere ihanitse, igiciro cyiza module ijyanye na Gigabit Ethernet na 10/100 / 1000BASE-T nkuko bigaragara muri IEEE 802. 3-2002 na IEEE 802.3ab, ishyigikira 10 / 100 / 1000Mbps data- igipimo kigera kuri metero 100 kigera hejuru yicyuma kidafunze-icyiciro cya 5 umugozi. JHA3401 ishyigikira 10/100/1000 Mbps yuzuye ya duplex yamakuru-ihuza hamwe ninzego 5 za Pulse Amplitude Modula-tion (PAM). Byose uko ari bine muri kabili bikoreshwa nigipimo cyibimenyetso kuri 250Mbps kuri buri jambo. JHA3401 itanga amakuru yindangamuntu asanzwe yubahiriza SFP MSA, ushobora kuboneka hamwe na aderesi ya A0h ukoresheje 2-wire serial CMOS EEPROM protocole. IC yumubiri irashobora kandi kuboneka binyuze muri bisi 2-seri ya bisi kuri aderesi ACh.

•SFP Kuri Kwakira Umuhuza

Inyandiko:

1. Ikosa rya TX ntabwo rikoreshwa kandi rihora rihambiriwe kubutaka binyuze muri 100 ohm résistor.

2. TX Guhagarika nkuko byasobanuwe muri MSA ntabwo ikoreshwa kuri module 1000BASE-T, ariko ikoreshwa muburyo bworoshye nkigitekerezo cyo kugarura ASIC y'imbere. Iyi pin yakuwe muri module hamwe na 4.7 KW irwanya.

Hasi (0 - 0.8 V): Transceiver on

Hagati (0.8 V na 2.0 V): Ntisobanuwe

Hejuru (2.0 - 3.465 V): Transceiver muburyo bwo gusubiramo

Fungura: Transceiver muburyo bwo gusubiramo

3. Mod-Def 0,1,2. Nibisobanuro byerekana module. Bagomba gukururwa hamwe na 4.7-10 KW ristoriste kurubaho rwakira kugirango batange munsi ya VCCT + 0.3 V cyangwa VCCR + 0.3 V.

Mod Def 0 ihambiriwe kubutaka binyuze muri 100 ohm résistor kugirango yerekane ko module ihari.

Mod-Def 1 numurongo wisaha yumurongo wibice bibiri byuruhererekane rwindangamuntu

Mod-Def 2 ni umurongo wumurongo wibice bibiri byuruhererekane rwindangamuntu

4. LVTTL ijyanye na voltage ntarengwa ya 2.5V. Ntabwo ashyigikiwe kuri HTSFP-24-111X

5. RD - / +: Ibi nibisubizo bitandukanye byo kwakira. Bahujwe ac 100 imirongo itandukanye ya ohm igomba guhagarikwa hamwe na 100 ohm itandukanye kubakoresha SerDes. Ac guhuza bikorwa imbere muri module bityo ntibisabwa kurutonde rwabakiriye. Umuvuduko wa voltage kuriyi mirongo uzaba hagati ya 370 na 2000 mV itandukanye (185 - 1000 mV imwe yarangiye) iyo irangiye neza. Izi nzego zirahujwe na CML na LVPECL voltage swing.

6. VCCR na VCCT nibyo byakira kandi bitanga amashanyarazi. Basobanuwe nka 3.3 V ± 5% kuri pin ya SFP. Umubare ntarengwa wo gutanga ni hafi 300mA kandi bifitanye isano no kwihuta mubisanzwe ntibishobora kurenza mA 30 hejuru ya leta ihagaze nyuma ya nanosekondi 500.

7. TD - / +: Izi ninyandiko zinyuranye zohereza. Bahujwe ac gutandukanya imirongo hamwe na 100 W itandukanyirizo imbere muri module. Ac guhuza bikorwa imbere muri module bityo ntibisabwa kurutonde rwabakiriye. Inyongeramusaruro izemera itandukaniro rya mV 500 - 2400 mV (250–1200 mV imwe yarangiye), nubwo bisabwa ko indangagaciro ziri hagati ya 500 na 1200 mV zitandukanye (250 - 600 mV imwe yarangiye) gukoreshwa mubikorwa byiza bya EMI. Izi nzego zirahujwe na CML na LVPECL voltage swing.

Igishushanyo cyabashitsi bahuza bahagarika pin nimero

•+ 3.3V Umuyoboro w'amashanyarazi

JHA3401 ifite voltage yinjiza ya 3.3 V +/- 5%. Umuvuduko ntarengwa wa 4 V ntabwo wemerewe gukora ubudahwema.

Icyitonderwa: Gukoresha ingufu hamwe na surge bigezweho birenze indangagaciro zagaragaye muri SFP MSA

•Ibimenyetso Byihuta

MOD_DEF (1) (SCL) na MOD_DEF (2) (SDA), ni ibimenyetso bifungura imiyoboro ya CMOS. Byombi MOD_ DEF (1) na MOD_DEF (2) bigomba gukururwa kuri host_Vcc.

•Umuvuduko wihuse wamashanyarazi

Ibimenyetso byihuta byose ni AC-ihujwe imbere.

• Ibisobanuro rusange

•Ibidukikije

JHA3401 ifite intera yagutse kuva kuri 0 ° C kugeza kuri + 85 ° C yubushyuhe nkuko bigaragara mu mbonerahamwe ya 7.

•Ikirangantego cy'Urwibutso

•Ibipimo bya mashini

Ibipimo bya mashini ya Transceiver

JHA ifite uburenganzira bwo guhindura ibicuruzwa cyangwa amakuru akubiyemo hano nta nteguza. Nta buryozwe bufatwa nkibikoreshwa cyangwa gusaba. Nta burenganzira buri muri patenti iherekeza kugurisha ibicuruzwa cyangwa amakuru ayo ari yo yose.
