Notes:

7.

High-frequency AC electricals are guaranteed by design and characterization.

8.

Duty cycle skew guaranteed only for differential operation measured from the cross point of the input to the crosspoint of the output.

9.

INL (Integral Non-Linearity) is defined from its corresponding point on the ideal delay versus D[9:0] curve as the deviation from its ideal delay. The

maximum difference is the INL. Theoretical Ideal Linearity (TIL) = (measured maximum delay – measured minimum delay) ÷ 1024. INL = measured

delay – measured minimum delay + (step number

∞ TIL).

10. This setup time defines the amount of time prior to the input signal. The delay tap of the device must be set.

11. This setup time defines the amount of the time that /EN must be asserted prior to the next transition of IN, /IN to prevent an output response greater

than ±75mV to the IN, /IN transition.

12. Hold time is the minimum time that /EN must remain asserted after a negative going IN or a positive going /IN to prevent an output response

greater than ±75mV to the IN, /IN transition.
