In addition, the small-sized DVI in above-described embodiment provided by the invention is with equalization function joint can also have following additional technical feature:
Particularly, described equalizer amplifier is arranged at the front end of described keyset, and described power management chip is arranged at the rear end of described keyset.
Small-sized according to an embodiment of the invention DVI is with equalization function joint, particularly equalizer amplifier and power management chip are separately positioned on the relative position of front-end and back-end of keyset, namely method power management chip being distributed in keyset rear end is adopted to reduce joint area and length, function of keeping in balance is impregnable while, can be cost-saving.
Preferably, also comprise: cable, described cable passes through cable tap setting in the upper end of described keyset; And described DVI male joint is arranged at the lower end of described keyset.
Small-sized according to an embodiment of the invention DVI is with equalization function joint, by cable is also arranged at relative position with DVI male joint in keyset, can reduce joint area and length further.
Preferably, described keyset is PCB keyset.
Preferably, described small-sized DVI is with the length of equalization function joint to be less than preset length value.
Preferably, described preset length value is 3.5 centimetres.
Small-sized according to an embodiment of the invention DVI is with equalization function joint, joint area and length is reduced by adopting method power management chip being distributed in keyset rear end, particularly, can the length of equalization function joint be with to be limited in certain preset range small-sized DVI, such as, be less than preset length and be worth 3.5 centimetres, namely the joint that cannot realize equalization function is equivalent to, further, owing to making DVI cable connector the same with ordinary couplings large, therefore can install in existing pipeline easily, applicability is strong, function of keeping in balance is impregnable while, more attractive in appearance, reliability is also higher because moment is little.
