System Design Information
Figure 59. Driver Impedance Measurement
The output impedance of the RapidIO port drivers targets 200-
differential resistance. The value of this 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 60 summarizes the signal impedance targets. The driver impedance are targeted at minimum VDD, nominal
OVDD, 105°C.
17.6 Configuration Pin Muxing
The MPC8560 provides the user with power-on configuration options which can be set through the use of external
pull-up or pull-down resistors of 4.7 k
on certain output pins (see customer visible configuration pins). These pins
are generally used as output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins while
HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled and the I/O
circuit takes on its normal function. Most of these sampled configuration pins are equipped with an on-chip gated
