* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those
indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is not implied.

1. Driving 50Ω transmission lines
2. Part–to–part skew at a given temperature and voltage
3. Final specification limits will be determined from matrix lot material. 800ps is the “best estimate” based on initial material and experience with
previous products.
