I was trying to determine the max frequency that can be clocked thru the Virtex-4 FPGA pins. While referring the Virtex-4 User Guide the (DC and Switching characteristics) Section of the book has blank columns. Although the Virtex-4 FPGA Handbook mentions the capabiltiy to meet different I/O standards, I was wondering has anyone been able to exercise the I/Os of the Virtex Family above 300MHz. Thanks -Azam
Has anybody run Virtex-4 FPGAs at 300MHz+ interface speed?

Which speed grade? You may want to check the latest user guide and data sheet.

Azam, There are demo pcb's I have seen for 333MHz DDR SDRAM. Austin azam wrote:> I was trying to determine the max frequency that can be clocked thru > the Virtex-4 FPGA pins.
