On-Chip Series Termination with Calibration
Arria II GX devices support R
calibration circuit compares the total impedance of the I/O buffer to the external
25- ±1% or 50- ±1% resistors connected to the RUP and RDN pins, and dynamically
enables or disables the transistors until they match.
The R
occurs at the end of device configuration. When the calibration circuit finds the
correct impedance, it powers down and stops changing the characteristics of the
drivers.
