NOTE 1. Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device

is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal

equilibrium has been reached under these conditions.

NOTE 4. Measured from the differential input cross point to the differential output crossing point.

NOTE 5. Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential output

cross point.

NOTE 6. This parameter is defined in accordance with JEDEC Standard 65.

NOTE 7. Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and

with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross point.

NOTE 9. Measurement taken from single-ended waveform.

NOTE 10. Measured at crossing point where the instantaneous voltage value of the rising edge of Qx equals the falling edge of nQx.



See Parameter Measurement Information Section.

NOTE 11. Refers to the total variation from the lowest crossing point to the highest, regardless of which edge is crossing. Refers to all crossing

points for this measurement. See Parameter Measurement Information Section.

NOTE 12. Defined as the total variation of all crossing voltage of rising Qx and falling nQx. This is the maximum allowed variance in the

NOTE 13. Measurement taken from differential waveform.

NOTE 14. Measurement from -150mV to +150mV on the differential waveform (derived from Qx minus nQx). The signal must be monotonic

through the measurement region for rise and fall time. The 300mV measurement window is centered on the differential zero crossing.

NOTE 15. Matching applies to rising edge rate for Qx and falling edge rate for nQx. It is measured using a ±75mV window centered on the

median cross point where Qx rising meets nQx falling.

NOTE 16. Assuming 50% input duty cycle. Data taken at ƒ

 200MHz, unless otherwise specified.
