Requirement, Units 1,5 Gps 3Gps 6 Gps Bulk le or kplne:, Differentil impene ohm 100 ± g Common-moe impene ohm 32,5 ± 7,5 Mte onnetors:, f Differentil impene ohm 100 ± g e f g All mesurements re me through mte onnetor pirs The equivlent mximum TDR rise time from 20 % to 80 % shll e 70 ps. Filtering my e use to otin the equivlent rise time. The filter onsists of the two-wy lunh/return pth of the test fixture, the two-wy lunh/return pth of the test le, n the softwre or hrwre filtering of the TDR sope. The equivlent rise time is the rise time of the TDR sope output fter pplition of ll filter omponents. When onfiguring softwre or hrwre filters of the TDR sope to otin the equivlent rise time, filtering effets of test les n test fixtures shll e inlue. The impene mesurement ientifies the impene mismthes present in the ulk le or kplne when terminte in its hrteristi impene. This mesurement exlues mte onnetors t oth ens of the ulk le or kplne, when present, ut inlues ny intermeite onnetors or splies. Where the ulk le or kplne hs n eletril length of > 4 ns the proeure etile in SFF-8410, or n equivlent proeure, shll e use to etermine the impene. The ifferene in mesure impene to SIGNAL GROUND on the plus n minus terminls on the interonnet, trnsmitter evie, or reeiver evie, with ifferentil test signl pplie to those terminls.
