and cal_blk_powerdown ports in the ALTGX MegaWizard Plug-In Manager to control
the calibration block. Drive the cal_blk_clk port of all ALTGX instances that are
associated with the same calibration block from the same input pin or logic.

Notes to
(1) You must connect a separate 2 k (tolerance max ± 1%) external resistor on each RREF pin in the Arria II GX and GZ
(2) This is the input clock to the calibration block. You can use dedicated clock routes such as the global or regional clock;
(3) The calibration block restarts the calibration process following de-assertion of the cal_blk_powerdown status.
device to GND. To ensure proper operation of the calibration block, the RREF resistor connection in the board must
be free from external noise.
however, if you do not have a suitable input reference clock or dedicated clock routing resources available, use
divide-down logic from the FPGA fabric to generate a slow clock, local clocking routing, or both.
Drive this signal of all ALTGX instances that are associated with the same calibration block from the same input or
logic.
