Freescale Semiconductor
Third, between the device and any SerDes voltage regulator there should be a 10-F, low
equivalent series resistance (ESR) SMT tantalum chip capacitor and a 100-F, low ESR SMT
tantalum chip capacitor. This should be done for all SerDes supplies.

Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active low inputs should be tied to NVDD, GVDD, LVDD, LVDDA, or LVDDB as required.
Unused active high inputs should be connected to VSS. All NC (no-connect) signals must remain
unconnected.
Power and ground connections must be made to all external VDD, NVDD, GVDD, LVDD, LVDDA, LVDDB,
and VSS pins of the device.

Output Buffer DC Impedance
The MPC8313E drivers are characterized over process, voltage, and temperature. For all buses, the driver
is a push-pull single-ended driver type (open drain for I2C).
To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to NVDD
or VSS. Then, the value of each resistor is varied until the pad voltage is NVDD/2 (see Figure 60). The
output impedance is the average of two components, the resistances of the pull-up and pull-down devices.
When data is held high, SW1 is closed (SW2 is open), and RP is trimmed until the voltage at the pad equals
NVDD/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 60. Driver Impedance Measurement
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.
