Figure 6–3. Cyclone III Device Family OCT Block Placement
Each calibration block comes with a pair of RUP and RDN pins. When used for
calibration, the RUP pin is connected to V
50-Ω ±1% resistor for an on-chip series termination value of 25 Ω or 50 Ω,
respectively. The RDN pin is connected to GND through an external 25-Ω ±1% or 50-Ω
The external resistors are compared with the internal resistance using comparators.
The resultant outputs of the comparators are used by the OCT calibration block to
dynamically adjust buffer impedance.
During calibration, the resistance of the RUP and RDN pins varies. For an estimate of
the maximum possible current through the external calibration resistors, assume a
minimum resistance of 0 Ω on the RUP and RDN pins during calibration.
±1% resistor for an on-chip series termination value of 25 Ω or 50 Ω, respectively.
