Sample tested during initial release and after any redesign or process change that could affect this parameter. All input signals are specified with tr = tf = 5 ns
(10% to 90%) and timed from a voltage level of 1.6 V.
See Figure 3, Figure 4, and the ADE7753 Serial Interface section.
Minimum time between read command and data read for all registers except waveform register, which is t
Measured with the load circuit in Figure 2 and defined as the time required for the output to cross 0.8 V or 2.4 V.
Derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit in Figure 2. The measured number is then extrapolated back
to remove the effects of charging or discharging the 50 pF capacitor. This means that the time quoted in the timing characteristics is the true bus relinquish time of
the part and is independent of the bus loading.
