Notes
:
4.
Outputs terminated with 50 to VDD/2. See Parameters measurements 3.3V load test circuit.
5.
The circuit is designed to meet the AC specifications shown in the above table(s) after thermal equilibrium has been established.
6.
Defined as skew between outputs at the same supply voltage and with equal load conditions; Measured at the output differential crossing points.
