Hi all, I am asked to design SSTL2 Tx to drive 50ohm line (unterminated). What i did is, sized my buffer to give first step equal to VDDS/2 at near end with 50ohm line connected. Without giving any look to SSTL2 JEDEC specs. It can drive SSTL2 Rx. The confusion is, is this realy a SSTL2 Tx? If Yes, how do i label it as class-I or class-II, because it comes out to be some where in between the two? For class-II it is weak and for class-I it is too strong. If No, than that means we cannot have good SSTL2 Tx to drive 50ohm line (unterminated)? I am stucked....please help, i am missing something.
