hi,all: Could anyone please tell me the fundamental concept of these things as follows? I'm confused. LVDS(low voltage digital system) TMDS(????????), what's these? When I simulate, I just to see they're only nets,such as LVDS to layout in differential pair(Txout+,Txout-). Related to other nets, any particular spec. about LVDS or TMDS? Anyone giving me any help will be appreciated. Best regards, Greg Tel:+86-21-54261366 Ext:1746 Mailto:fu.greg@xxxxxxxxxxxx Inventec(ShangHai) Co.,Ltd.
