System Design Information
Figure 20 describes the driver impedance measurement circuit described above.
Figure 20. Driver Impedance Measurement Circuit
Alternately, the following is another method to determine the output impedance of the MPC7410. A voltage
source, Vforce, is connected to the output of the MPC7410, as in Figure 21. Data is held low, the voltage
source is set to a value that is equal to (L2)OVDD/2, and the current sourced by Vforce is measured. The
voltage drop across the pull-down device, which is equal to (L2)OVDD/2, is divided by the measured current
to determine the output impedance of the pull-down device, RN. Similarly, the impedance of the pull-up
device is determined by dividing the voltage drop of the pull-up, (L2)OVDD/2, by the current sank by the
pull-up when the data is high and Vforce is equal to (L2)OVDD/2. This method can be employed with either
empirical data from a test setup or with data from simulation models, such as IBIS.
RP and RN are designed to be close to each other in value. Then, Z0 = (RP + RN)/2. Figure 21 describes the
alternate driver impedance measurement circuit.
