How does the Bitgen configrate setting correspond to the actual CCLK frequency?
The configrate setting corresponds directly to the CCLK frequency.
2 -> 2 MHz
6 -> 6 MHz
9 -> 9 MHz
13 -> 13 MHz
Be aware that there is a Tolerance of +/- 50% on this frequency generated by this internal oscillator. This is specified by the FMCCKTOL parameter in the Virtex-5 Data Sheet (DS202) which can be found here:
