1. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the

differential output signals. See Definitions and Testing of ECLinPS AC Parameters in Chapter 1 (page 1–12) of the Motorola High Performance

ECL Data Book (DL140/D).

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. See

Definitions and Testing of ECLinPS AC Parameters in Chapter 1 (page 1–12) of the Motorola High Performance ECL Data Book (DL140/D).

3. The within–device skew is defined as the worst case difference between any two similar delay paths within a single device.

4. VPP(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The VPP(min) is AC limited

for the LVE222. A differential input as low as 50 mV will still produce full ECL levels at the output.

5. VCMR 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 VPP(min).
