1. See Standard Frequencies and Ordering Information.
2. Parameters are tested with production test circuit below (Fig 1).
3. Parameters are tested at ambient temperature with test limits guard banded for specified operating temperature.
4. Measured from 20% to 80% of a full output swing (Fig 2).
5. Not tested in production, guaranteed by design, verified at qualification.
6. Minimum Input Low Voltage not to exceed 2.125 V. Minimum Input High Voltage not to go below 1.49 V.
7. AC coupling is recommended. There is an internal pull-up and pull-down resistor on all clock inputs (Fin, BRCLK).
8. Measured using a Wavecrest SIA3300. Best results are realized with a differential input.
