System Design Information
When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals
OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each
other in value. Then, Z0 = (RP + RN)/2.
Figure 59. Driver Impedance Measurement
The output impedance of the RapidIO port drivers targets 200-
resistance and the strength of the driver’s current source can be found by making two measurements. First,
the output voltage is measured while driving logic 1 without an external differential termination resistor.
The measured voltage is V1 = Rsource × Isource. Second, the output voltage is measured while driving logic
1 with an external precision differential termination resistor of value Rterm. The measured voltage is
V2 = 1/(1/R1 +1/R2)) × Isource. Solving for the output impedance gives Rsource = Rterm × (V1/V2 –1). The
drive current is then Isource =V1/Rsource.
Table 61 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD,
nominal OVDD, 105°C.
