Hi,
I need to have a single chip DDR1 (160 MHz, 16-Bit) memory for a processor.
I don't want to provide VTT terminations. I'll keep the trace length as
minimum as possible. I may provide series termination but I haven't done
pre-layout simulation yet.
Can somebody please clarify whether it can be designed without VTT
termination? If yes, what can be the maximum trace length I go for? If I'm
providing series termination, should I provide at both the ends for
bi-directional signals?
Regards,
Kathir
