Lus Cim 1: QSFP-DD siv hauv av (GND) rau tag nrho cov teeb liab thiab muab khoom (lub zog). Tag nrho cov muaj nyob rau hauv QSFP-DD module thiab tag nrho cov module voltages raug xa mus rau lub hwj chim ial no tshwj tsis yog tau sau tseg. Txuas cov no ncaj qha mus rau tus tswv tsev lub teeb liab-hom gr und dav hlau .

Nco tseg 2: VccRx, VccRxl, Vccl, Vcc2, VccTx thiab VccTxl yuav tsum tau siv ua ke. Cov kev xav tau uas tau teev tseg rau tus tswv tsev sab ntawm Host Card Edge Connect r yog teev nyob rau hauv Table 7. VccRx , VccRxl , Vccl , Vcc2 , VccTx thiab VccTxl tuaj yeem txuas nrog hauv lub module hauv ib qho kev sib xyaw ua ke. Lub connector Vcc pi s yog txhua qhov ntsuas rau qhov siab tshaj plaws tam sim no ntawm 1000 mA.

Lus Cim 3: Tag nrho cov Vend r Specific, Reserved, N Txuas thiab ePPS (yog nt siv) tus pins yuav raug txiav nrog 50 Ohms rau hauv av ntawm h st. Pad 65 (Tsis Muaj Txuas) yuav tsum tau tso tseg tsis txuas hauv lub module. Vend r tshwj xeeb thiab Reserved pads yuav tsum muaj impedance rau GND uas ntau dua 10 kOhms thiab tsawg dua 100 pF.

Lus Cim 4: Plug Sequence qhia txog qhov sib txuas ntawm tus tswv tsev txuas thiab

module. Cov kab ke yog lA, 2A, 3A, lB, 2B, 3B. (saib daim duab 2 fr pad l cations)

kev sib cuag A yuav ua, ces tawg c ntact nrog ntxiv tional QSFP-DD pads .

Ib ntus lA,lB yuav ces tshwm sim ib txhij , ua raws los ntawm 2A,2 b,ua los ntawm 3A,3B .
