lvttl in ise ucf
Please,
I am trying to acquire a databus (12 bits) from an A/D converter
(with sample rate configured at 50MHz) using SPARTAN IIe and IO buffer configured as LVTTL (SLEW) in the input pins of UCF file (ISE 6.1i).
Is the LVTTL (SLEW) IOB fast enough to be activated by the databus
at 50Mhz ?
Or I should replace the LVTTL IOB type for another one available...
In other hands, what is the best IOB choice for this case?
Thanks in advance...
