Hello All,
Does anyone know what the real max DCM CLKIN speed of Spartan-3E stepping 0 is. In the datasheets it says 90 Mhz but in the errata is says 120 MHz. We have one design (with clock feedback from an external pin) where it fails at 100 MHz... Does the same speed limit apply to the CLKFB pin as well..
Thanks,
Finn
