Nco tseg:
1: GND yog lub cim rau lub teeb liab thiab cov khoom siv (lub zog) ntau rau cov qauv. Tag nrho cov muaj nyob rau hauv lub module thiab tag nrho cov module voltages raug xa mus rau qhov muaj peev xwm tshwj tsis yog tau sau tseg. Txuas cov no ncaj qha mus rau tus tswv tsev lub teeb liab-cov dav hlau hauv av.
2: Vcc Rx, Vcc1 thiab Vcc Tx yuav tsum tau siv ib txhij. Vcc Rx Vcc1 thiab Vcc Tx tuaj yeem txuas nrog hauv qhov module hauv ib qho kev sib xyaw ua ke. Cov pins txuas yog txhua qhov ntsuas rau qhov siab tshaj plaws tam sim no ntawm 1000 mA. Pom zoo host board power supply filtering yog qhia hauv qab no .
3: ModSelL yog tus pin input. Thaum tuav qis los ntawm tus tswv tsev, lub module teb rau 2-wire serial lus txib. ModSelL tso cai rau siv ntau lub modules ntawm ib qho 2-wire interface tsheb npav. Thaum ModSelL yog "High", lub module yuav tsum tsis teb los yog lees paub ib qho 2- xov tooj sib txuas lus los ntawm tus tswv tsev. ModSelL teeb liab input node yuav tsum tau beased rau lub xeev "High" nyob rau hauv lub module. Txhawm rau kom tsis txhob muaj kev tsis sib haum xeeb, tus tswv tsev yuav tsum tsis txhob sim 2- xov tooj sib txuas lus hauv ModSelL de-assert lub sij hawm tom qab ib qho modules raug xaiv. Ib yam li ntawd, tus tswv tsev yuav tsum tau tos tsawg kawg rau lub sijhawm ntawm ModSelL lees paub lub sijhawm ua ntej kev sib txuas lus nrog cov qauv xaiv tshiab. Lub sijhawm lees paub thiab tsis lees paub lub sijhawm ntawm cov qauv sib txawv tuaj yeem sib tshooj ntev li ntev tau raws li cov kev xav tau saum toj no.
4: ResetL tus pin yuav tsum rub mus rau Vcc hauv lub module. Ib theem qis ntawm ResetL tus pin ntev dua li qhov tsawg kawg nkaus mem tes ntev (t_Reset_init) pib dua ib qho kev ua tiav, rov qab tag nrho cov neeg siv cov teeb tsa module rau lawv lub xeev qub. Module Reset Assert Time (t_init) pib ntawm qhov nce siab tom qab qhov qis qis ntawm ResetL tus pin raug tso tawm. Thaum lub sijhawm ua kom rov pib dua (t_init) tus tswv tsev yuav tsum tsis saib xyuas txhua qhov xwm txheej kom txog rau thaum lub module qhia txog qhov ua tiav ntawm qhov rov ua haujlwm cuam tshuam. Lub module qhia qhov no los ntawm kev lees paub "qis" ib qho IntL teeb liab nrog cov ntaub ntawv_Tsis yog_Npaj me ntsis negated. Nco ntsoov tias thaum lub zog nce (nrog rau qhov kub ntxig) lub module yuav tsum tshaj tawm qhov ua tiav ntawm kev rov pib cuam tshuam yam tsis tas yuav rov pib dua.
5: Tsis tshua muaj kev ceeb toom uas tsis yog SCL thiab SDA yog raws li qhov qis qis TTL (LVTTL) ua haujlwm ntawm Vcc. Vcc hais txog cov khoom siv hluav taws xob dav dav ntawm VccTx, VccRx, Vcc_tus tswv lossis Vcc1.
Cov tswv tsev yuav tsum siv lub rub-up resistor txuas nrog Vcc_tus tswv ntawm txhua qhov ntawm 2-wire interface SCL (clock), SDA (cov ntaub ntawv), thiab tag nrho cov kev tawm suab qis. SCL thiab SDA yog qhov kub plug interface uas yuav txhawb nqa lub tsheb npav topology.
6: ModPrsL raug rub mus rau Vcc_Tswj rau ntawm lub rooj tsav xwm tswj hwm thiab hauv av hauv qhov module. Cov ModPrsL yog asserted "Low" thaum tso thiab deasserted "High" thaum lub module yog lub cev tsis tuaj ntawm lub party connector.
7: IntL yog tus pin tso zis. Thaum IntL yog "Low", nws qhia tau hais tias muaj peev xwm ua haujlwm tau txhaum los yog ib qho xwm txheej tseem ceeb rau tus tswv tsev. Tus tswv tsev txheeb xyuas qhov chaw ntawm kev cuam tshuam siv {{0}}wire serial interface. Lub IntL tus pin yog qhib cov khoom tso tawm thiab yuav tsum tau rub mus rau tus tswv tsev muab hluav taws xob ntawm lub rooj tsavxwm. Tus INTL tus pin yog deasserted "High" tom qab ua tiav ntawm kev pib dua, thaum byte 2 ntsis 0 (Cov ntaub ntawv Tsis Npaj) yog nyeem nrog tus nqi ntawm '0' thiab tus chij teb tau nyeem (saib SFF-8636 ).
8: Tus pin LPMode yuav tsum rub mus rau Vcc hauv lub module. Tus pin yog kev tswj hwm kho vajtse
siv los muab cov modules rau hauv hom qis zog thaum siab. Los ntawm kev siv tus pin LPMode thiab kev sib xyaw ua ke ntawm Lub Hwj Chim{{0}}override, Fais fab_set thiab High_Power_Class_ Pab kom software tswj cov khoom siv (chaw nyob A0h, byte 93 khoom 0,1,2), tus tswv tsev tswj hwm lub zog npaum li cas lub module tuaj yeem tawg.
9: Rx(n)(p/n) yog module txais cov ntaub ntawv tawm. Rx(n)(p/n) yog AC-coupled 100 Ohm Cov kab sib txawv uas yuav tsum tau txiav nrog 100 Ohm sib txawv ntawm tus tswv ASIC (SerDes). Lub AC coupling nyob rau hauv lub module thiab tsis tas yuav tsum tau ntawm lub Rooj Tswjhwm Saib. Rau kev ua haujlwm ntawm 28 Gb / s cov qauv tsim nyog (piv txwv li, OIF CEI v3.1) txhais cov teeb liab uas yuav tsum tau muaj ntawm cov kab sib txawv ntawm kev kub ceev. Rau kev ua haujlwm ntawm tus nqi qis, xa mus rau cov qauv tsim nyog.
Nco tseg: Vim tias muaj peev xwm nkag mus rau QSFP thiab QSFP + cov cuab yeej cuab tam rau hauv tus tswv tsev
tsim los rau kev ua haujlwm nrawm dua, nws raug pom zoo tias qhov kev puas tsuaj ntawm qhov pib lub tswv yim tswv yim yuav tsum tsawg kawg yog 1600 mV ncov kom ncov sib txawv. Output squelch rau poob ntawm optical input teeb liab, hereafter Rx Squelch, yuav tsum tau thiab yuav tsum ua raws li nram no. Nyob rau hauv qhov xwm txheej ntawm lub teeb liab kho qhov muag ntawm ib qho channel dhau los ua qhov sib npaug lossis tsawg dua li qib uas yuav tsum tau lees paub LOS, tom qab ntawd tus txais cov ntaub ntawv tso tawm rau cov channel yuav tsum tau rub los yog xiam oob qhab. Nyob rau hauv lub xeev squelched los yog neeg xiam oob khab cov zis impedance theem yog tswj thaum lub sib txawv voltage viav vias yuav tsum tsawg tshaj li 50 mVpp. Hauv kev ua haujlwm ib txwm muaj cov ntaub ntawv qub muaj Rx Squelch nquag. Rx Squelch tuaj yeem kaw tau siv Rx Squelch Disable los ntawm 2-wire serial interface. Rx Squelch Disable yog qhov xaiv tau. Rau cov ntsiab lus tshwj xeeb xa mus rau SFF-8636.
10: Tx(n)(p/n) is module transmitter data inputs. Lawv yog AC-coupled 100 Ohm cov kab sib txawv nrog 100 Ohm sib txawv txiav tawm hauv lub module. Lub AC coupling nyob rau hauv lub module thiab tsis tas yuav tsum tau ntawm lub Rooj Tswjhwm Saib. Rau kev ua haujlwm ntawm 28 Gb / s qhov cuam tshuam cov qauv (piv txwv li, OIF CEI v3.1) txhais cov teeb liab yuav tsum tau ntawm cov kab sib txawv ntawm kev kub ceev. Rau kev ua haujlwm ntawm tus nqi qis, xa mus rau cov qauv tsim nyog. Vim tias qhov muaj peev xwm ntawm kev ntxig cov modules rau hauv lub tswv yim tsim los rau kev ua haujlwm qis qis, qhov kev puas tsuaj ntawm cov khoom siv module yuav tsum yog tsawg kawg yog 1600 mV ncov mus rau qhov sib txawv. Output squelch, hereafter Tx Squelch, rau poob ntawm input signal, hereafter Tx LOS, yog ib qho kev xaiv muaj nuj nqi. Qhov twg siv nws yuav tsum ua raws li hauv qab no. Nyob rau hauv qhov kev tshwm sim ntawm qhov sib txawv, ncov-rau-npaum hluav taws xob teeb liab ntawm ib qho channel dhau los ua tsawg dua 50 mVpp, tom qab ntawd lub transmitter optical output rau cov channel yuav tsum tau squelched los yog neeg xiam oob khab thiab cuam tshuam TxLOS chij teeb. Qhov twg squelched, lub transmitter OMA yuav tsum tsawg dua los yog sib npaug rau -26 dBm thiab thaum disabled lub transmitter hwj chim yuav tsum tsawg dua los yog sib npaug rau -30 dBm. Rau cov ntawv thov, xws li Ethernet, qhov twg lub transmitter off condition yog txhais nyob rau hauv cov nqe lus ntawm nruab nrab lub hwj chim, disabling lub transmitter yog pom zoo thiab rau daim ntaub ntawv, xws li InfiniBand, qhov twg lub transmitter tawm mob yog txhais nyob rau hauv cov nqe lus ntawm OMA, squelching lub transmitter yog pom zoo. Hauv kev ua haujlwm module, qhov twg Tx Squelch yog siv, rooj plaub ua ntej muaj Tx Squelch nquag. Tx Squelch tuaj yeem kaw tau siv Tx Squelch Disable los ntawm 2-wire serial interface. Tx Squelch Disable yog ib qho kev xaiv ua haujlwm. Rau cov ntsiab lus tshwj xeeb xa mus rau SFF- 8636.
