Thaum DDR txiav tawm resistor muab tso rau qhov tsis raug

Tam sim no, txoj hauj lwm ntawm qhov kev txiav tawm resistor hauv DDR module (ib lub tsav) sib raug rau qhov ntev ntawm qhov sib txawv ntawm khub.

Cov teeb liab ceev ceev tsis tuaj yeem muaj lub kaum sab xis, thiab 25G cov cim qhia yuav tsum tsis muaj qhov ntev ntev. Qhov no yog qhov kev paub txog SI (Signal Integrity).

Yog li, yog tias koj ntsib DDR module nrog qhov kev txiav tawm qhov hluav taws xob tsis raug, koj yuav xav li cas?

Txoj hauj lwm ntawm DDR module termination resistors, raws li tau hais los saum no, yog qhov tseem ceeb SI kev paub.

Lub DDR termination resistor yuav tsum muab tso rau thaum kawg. Tej zaum koj yuav xav tias qhov yuam kev zoo li no yuav tsum tsis txhob tshwm sim, tab sis hmoov tsis, Mr. High Speed tau pom ntau qhov xwm txheej zoo li no. Qhov tseeb, muaj ib rooj plaub uas txoj cai no tau ua txhaum cai - tsis yog thaum lub sijhawm tsim qauv, tab sis ntawm lub rooj tsavxwm uas twb tau tsim ...

Qhov no yog ib qho 1-rau-4 DDR3 module. Cov neeg siv khoom lub hom phiaj yog khiav ntawm 800M, tab sis lawv pom tias nws tsuas yog khiav ntawm 400M. Mr. Kev kub ceev pib xav tias nws yuav nyuaj rau nrhiav thiab txhim kho tus qauv tsim, tab sis raws li kev tshuaj xyuas cov neeg siv khoom lub rooj tsavxwm, nws tau pom tias qhov kev txiav tawm resistors tau muab tso rau qhov tsis raug. Lawv tau muab tso rau ntawm thawj qhov chaw, raws li pom nyob rau hauv lub moos teeb liab topology hauv qab no. Lub termination resistor yog cim los ntawm tus ncej liab.

Thawj kauj ruam peb yuav tsum tau ua yog txhawm rau txheeb xyuas cov txiaj ntsig ntawm kev simulation. Peb simulated lub 800M moos thiab chaw nyob teeb liab sib cais, thiab cov qhabnias tiag tiag matched qhov kev xeem.

Lub moos teeb liab ua tsis tiav ntawm granule 2, thiab qhov chaw nyob teeb liab kuj tseem tsis muaj zog. Tsis tas li ntawd, cov neeg siv khoom tau hais tias lub rooj tsavxwm tuaj yeem khiav ntawm 400M, yog li peb kuj simulated qhov xwm txheej ntawm 400M.

Ntawm 400M, los ntawm kev simulation pom, ob lub moos thiab chaw nyob teeb liab muaj qee qhov npoo, thiab nws muaj peev xwm ua rau qhov kev xeem dhau.

Qhov teeb meem thiab kev daws teeb meem rau lub rooj tsavxwm no tau meej. Tom qab rov tsim kho lub rooj tsavxwm, peb muab tso rau qhov kev txiav tawm ntawm qhov chaw kom raug. Lub rooj tsavxwm dhau qhov kev xeem 800M yam tsis muaj teeb meem. Cov ntaub ntawv no yog "qhia" qhia peb tias qee cov kev cai tsis tuaj yeem raug ua txhaum cai, tshwj xeeb tshaj yog cov uas tau lees paub dav hauv kev lag luam. Txwv tsis pub, koj yuav ntsib kev ua tsis tiav hauv koj tus txheej txheem tsim.

Qhov teeb meem no hauv tsab xov xwm no yooj yim, tab sis kuv vam tias nws muab qee qhov kev tshoov siab rau txhua tus.
