•SFP rau Host Connector Pin Out

Nco tseg:

1. TX Fault tsis siv thiab ib txwm khi rau hauv av los ntawm 100 ohm resistor.

2. TX Disable raws li tau piav qhia hauv MSA tsis siv rau 1000BASE-T module, tab sis yog siv los ua kom yooj yim raws li cov tswv yim los rov pib lub ASIC sab hauv. Tus pin no yog rub tawm hauv lub module nrog 4.7 KW resistor.

Tsawg (0 - 0.8V): Transceiver rau

Nruab nrab (0.8 V thiab 2.0 V): Undefined

Siab (2.0 - 3.465 V): Transceiver nyob rau hauv lub xeev pib dua

Qhib: Transceiver hauv lub xeev pib dua

3. Mod-Def 0,1,2. Cov no yog cov module txhais pins. Lawv yuav tsum tau rub tawm nrog 4.7-10 KW resistor ntawm lub rooj tsavxwm lub rooj tsavxwm rau cov khoom siv tsawg dua VCCT + 0.3 V lossis VCCR + 0.3 V.

Mod Def 0 yog khi rau hauv av los ntawm 100 ohm resistor los qhia tias qhov module tam sim no.

Mod-Def 1 yog moos kab ntawm ob lub xov tooj sib txuas rau kev xaiv serial ID

Mod-Def 2 yog cov ntaub ntawv kab ntawm ob lub xov hlau serial interface rau xaiv serial ID

4. LVTTL tau tshaj qhov siab tshaj plaws ntawm 2.5V. Tsis txaus siab rau HTSFP-24-111X

5. RD-/+: Cov no yog qhov sib txawv receiver outputs. Lawv yog ac txuas nrog 100 ohm cov kab sib txawv uas yuav tsum tau txiav nrog 100 ohm sib txawv ntawm tus neeg siv SerDes. Lub ac coupling yog ua nyob rau hauv lub module thiab yog li tsis tas yuav tsum tau nyob rau hauv lub host board.
