JHA3401 10/100/1000BASE-T naxaasta SFP transceiver waa wax qabad sare, cutubka qiimaha wax ku ool ah u hoggaansanaanta Gigabit Ethernet iyo 10/100/1000BASE-T heerarka sida ku qeexan IEEE 802. 3-2002 iyo IEEE 802.3ab, kuwaas oo taageeraya IEEE 802.3ab, 100/1000Mbps xogta - heerka ilaa 100 mitir waxay gaadhaan in ka badan qaybta 5 fiilada oo aan gaashaan lahayn. JHA3401 waxay taageertaa 10/100/1000 Mbps xogta-duplex-ka buuxa ee isku xidhka xogta leh 5-heer Pulse Amplitude Modula-tion (PAM). Dhammaan afarta lamaane ee fiilada ku jira waxaa loo isticmaalaa cabbirka calaamadda 250Mbps ee lammaane kasta. JHA3401 waxa ay bixisa macluumaadka aqoonsiga taxanaha ah ee u hogaansan SFP MSA, kaas oo lagala gali karo ciwaanka A0h iyada oo loo marayo borotokoolka 2-fire ee CMOS EEPROM IC-ga jirka waxa kale oo laga geli karaa baska 2-fire ee ciwaanka ACh ah.

•SFP si ay u Martigeliso Xidhiidhiyaha Pin Out

Xusuusin:

1. Qaladka TX lama isticmaalo waxaana had iyo jeer lagu xidhaa dhulka iyada oo loo marayo resistor 100 ohm.

2. TX Disable sida lagu qeexay MSA laguma dabaqi karo moduleka 1000BASE-T, laakiin waxa loo isticmaalaa ku habboonaanta sidii talo-gelin si dib loogu dejiyo ASIC gudaha ah. Biinkan waxa lagu soo jiiday moduleka oo leh 4.7 KW iska caabin ah.

Hooseeyo (0 - 0.8 V): Transceiver shid

Inta u dhaxaysa (0.8 V iyo 2.0 V): Aan la qeexin

Sare (2.0 - 3.465 V): Transceiver oo ku jira xaalad dib u dejineed

Furan: Transceiver oo ku jira xaalad dib u dejineed

3. Mod-Def 0,1,2. Kuwani waa biinanka qeexida moduleka. Waa in lagu soo jiido 4.7-10 KW iska caabin ah oo ku yaal guddiga martida loo yahay si sahay ka yar VCCT + 0.3 V ama VCCR + 0.3 V.

Mod Def 0 wuxuu ku xidhan yahay dhulka iyada oo loo marayo 100 ohm resistor si loo muujiyo in cutubku jiro.

Mod-Def 1 waa xariiqda saacada ee laba xidhiidhiye silig ah oo loogu talagalay aqoonsiga taxanaha ikhtiyaariga ah

Mod-Def 2 waa xariiqda xogta ee laba xiriiriye xiriiriye oo silig ah oo loogu talagalay aqoonsiga taxanaha ikhtiyaariga ah

4. LVTTL oo la jaan qaadaya tamarta ugu badan ee 2.5V. Laguma taageero HTSFP-24-111X

5. RD-/+: Kuwani waa soo-saarka soo-dhoweynta ee kala duwan. Waxay ku xiran yihiin 100 ohm khadadka kala duwanaanta ah oo ay tahay in lagu joojiyo kala duwanaanshaha 100 ohm ee adeegsadaha SerDes. Isku-xidhka ac waxa lagu sameeyaa cutubka gudihiisa oo sidaas loogama baahna guddiga martida loo yahay. Lulida korantada ee khadadkan waxay noqon doontaa inta u dhaxaysa 370 iyo 2000 mV kala duwanaanshaha (185 - 1000 mV hal dhammaatay) marka si habboon loo joojiyo. Heerarkani waxay la jaan qaadayaan CML iyo LVPECL wareegyada korantada.

6. VCCR iyo VCCT waa aqbalaha iyo gudbinta sahayda korontada. Waxa lagu qeexaa inay yihiin 3.3 V ± 5% xagga pin-xidhaha SFP. Sahayda ugu badan ee hadda jirta waxay ku saabsan tahay 300mA iyo wakhtiga degdega ah ee la xidhiidha sida caadiga ah kama badna 30 mA oo ka sarreeya xaalad deggan kadib 500 nanoseconds.

7. TD-/+: Kuwani waa agabka gudbinta kala duwan. Waxay yihiin ac khadadka kala duwanaansho leh oo leh 100 W kala duwanaansho kala duwanaansho ah oo ku dhex jirta moduleka. Isku-xidhka ac waxa lagu sameeyaa cutubka gudihiisa oo sidaas loogama baahna guddiga martida loo yahay. Wax-soo-gelinta ayaa aqbali doona isbedbeddelka kala duwan ee 500 - 2400 mV (250-1200 mV hal dhammaad ah), inkastoo lagu taliyay in qiimaha u dhexeeya 500 iyo 1200 mV (250 - 600 mV hal dhammaad) loo isticmaalo waxqabadka EMI ugu fiican. Heerarkani waxay la jaan qaadayaan CML iyo LVPECL wareegyada korantada.

•+ 3.3V Volt Interface Power Koronto

JHA3401 waxay leedahay kala duwanaansho koronto gelineed oo ah 3.3 V +/- 5%. Korontada ugu badan ee 4V looma oggola hawlgal joogto ah.

Digniin: Isticmaalka tamarta iyo kor u kaca hadda ayaa ka sarreeya qiyamka la cayimay ee SFP MSA

•Calaamadaha Xawaaraha-hooseeya

MOD_DEF(1) (SCL) iyo MOD_DEF(2) (SDA), waa calaamado CMOS ah oo dareere furan. Labada MOD_ DEF(1) iyo MOD_DEF(2) waa in kor loogu qaadaa martigeliyaha_Vcc.

•Interface koronto-xawaaraha sare leh

Dhammaan calaamadaha xawaaraha sare waxay ku xiran yihiin AC gudaha.

• Tilmaamaha Guud
