Notes:
5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
6. VIHCMR 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 1.0V and then greater than or equal to VPP(min).
7. High-frequency AC parameters are guaranteed by design and characterization.
8. 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.
9. 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.
10. The within-device skew is defined as the worst-case difference between any two similar delay paths within a single device.
11. 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 SY100E222L as a differential input as low as 50 mV will still produce full ECL levels at the output.
