BREFCLK Pin Definitions (RocketIO Only)
These dedicated clocks use the same clock inputs for all packages:
For detailed information about using BREFCLK/BREFCLK2, including routing considerations and pin numbers for all
package types, refer to Chapter 2, "Digital Design Considerations," in the

Notes:
1. All dedicated pins (JTAG and configuration) are powered by V
2. Virtex-II Pro X devices XC2VPX20 and XC2VPX70 only. Each BREFCLK(N/P) differential clock input pair takes the place of one
