Notes to
(1) You must connect a separate 2 k(tolerance max ± 1%) external resistor on each RREF pin in the Arria II device to
(2) The Quartus II software automatically selects the appropriate calibration block based on the pin assignments of the
(3) For RREF pin information, refer to the
The calibration block internally generates a constant internal reference voltage,
independent of PVT variations and uses this voltage and the external reference
resistor on the RREF pin to generate constant reference currents. These reference
currents are used by the analog block calibration circuit to calibrate the transceiver
blocks.
The OCT calibration circuit calibrates the OCT resistors present in the transceiver
channels. You can enable the OCT resistors in the transceiver channels through the
ALTGX MegaWizard Plug-In Manager.

GND. To ensure proper operation of the calibration block, the RREF resistor connection in the board must be free from
external noise.
