NOTES:
2. Duty cycle skew guaranteed only for differential operation measured from the cross point of the input to the cross point of the output.
3. This set-up time defines the amount of time prior to the input signal the delay tap of the device must be set.
4. This set-up time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than
±
75mV to
that IN/IN transition.
5. This hold time is the minimum time that EN must remain asserted after a negative going IN or positive going IN to prevent an output response greater than
±
75mV to that IN/IN transition.
6. This release time is the minimum time that EN must be deasserted prior to the next IN/IN transition to ensure an output response that meets the specified
IN to Q propagation delay and transition times.
7. Specification limits represent the amount of delay added with the assertion of each individual delay control pin. The various combinations of asserted delay
control inputs will typically realize D
0
resolution steps across the specified programmable range.
8. The linearity specification guarantees to which delay control input the programmable steps will be monotonic (i.e. increasing delay steps for increasing
binary counts on the control inputs D
n
). Typically, the device will be monotonic to the D
0
input, however, under worst case conditions and process variation,
delays could decrease slightly with increasing binary counts when the D
0
input is the LSB. With the D
1
input as the LSB, the device is guaranteed to be
monotonic over all specified environmental conditions and process variation.
9. The jitter of the device is less than what can be measured without resorting to very tedious and specialized measurement techniques.
