Compliance Test and Measurement Load

The AC timing and voltage parameters must be verified at the measurement point, as specified within

0.2 inches of the package pins, into a test/measurement load shown in Figure 48.

NOTE

The allowance of the measurement point to be within 0.2 inches of the

package pins is meant to acknowledge that package/board routing may

benefit from D+ and D– not being exactly matched in length at the package

pin boundary. If the vendor does not explicitly state where the measurement

point is located, the measurement point is assumed to be the D+ and D–

package pins.
