Hejuru (2.0 ~ 3.3V): Ikwirakwiza ryahagaritswe
Fungura: Ikwirakwizwa ryahagaritswe
3. MOD-DEF 0,1,2 nibisobanuro byerekana module. Bagomba gukururwa hamwe na 4.7k ~ 10kΩresistor ku kibaho. Umuvuduko ukurura ugomba kuba VccT cyangwa VccR.
MOD-DEF 0 ishingiye kuri module kugirango yerekane ko module ihari.
MOD-DEF 1 numurongo wisaha yibice bibiri byuruhererekane rwindangamuntu.
MOD-DEF 2 numurongo wamakuru wibice bibiri byuruhererekane rwindangamuntu.
4. Logic 0 yerekana imikorere isanzwe; logique 1 yerekana gutakaza ibimenyetso. Muri leta yo hasi, ibisohoka bizakururwa kugeza munsi ya 0.8V.
5.Ibyo nibisohoka bitandukanye byakira. Biri imbere AC-ihujwe 100Ω imirongo itandukanye igomba guhagarikwa na 100Ω (itandukanye) kumukoresha SERDES.
6. Izi nizo zinyuranye zohereza ubutumwa. Ni AC-ihujwe, imirongo itandukanye hamwe 100Ω itandukanyirizo imbere muri module.
