Calibration Block  
Arria GX devices use the calibration block to calibrate on-chip  
termination for the PLLs and their associated output buffers and the  
terminating resistors on the transceivers. The calibration block counters  
the effects of process, voltage, and temperature (PVT). The calibration  
block references a derived voltage across an external reference resistor to  
calibrate the on-chip termination resistors on Arria GX devices. The  
calibration block can be powered down. However, powering down the  
calibration block during operations may yield transmit and receive data  
errors.
