1. The differential propagation delay is defined as the delay from the crossing point of the differential input signals to the crossing point of the
differential output signals.
2. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.
3. Enable is defined as the propagation delay from the 50% point of a negative transition on EN¯¯ to the 50% point of a positive transition on Q (or a
negative transition on Q¯ ). Disable is defined as the propagation delay from the 50% point of a positive transition on EN¯¯ to the 50% point of a
negative transition on Q (or a positive transition on Q¯).
4. The within-device skew is defined as the worst-case difference between any two similar delay paths within a single device.
5. The setup 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 (see Figure 1).
6. The 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 ±75 mV to that IN/IN¯¯ transition (see Figure 2).
7. The release time is the minimum time that EN¯¯ must be de-asserted prior to the next IN/IN¯¯ transition to ensure an output response that meets the
specified IN to Q propagation delay and output transition times (see Figure 3).
8. V
PP
is defined as the minimum peak-to-peak differential input swing for which AC parameters are guaranteed. The VPP(min) is AC limited for the
LVE111E, because differential input as low as 50 mV will still produce full ECL levels at the output.
9. V
CMR
is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level
must be such that the peak-to-peak voltage is less than 1.0 V and greater than or equal to V
PP
(min).
