2.6.1. Calibration Clock

For Arria II GX, Arria II GZ, Cyclone IV GX, and Stratix IV GX designs, ensure that you connect the calibration clock (cal_blk_clk) to a clock signal with the appropriate frequency range of 10 to 125 MHz. The cal_blk_clk ports on other components that use transceivers must be connected to the same clock signal.
