The pulse output FOUT is designed to assist with meter
calibration. Using the FREQ[2:0] pins, FOUT can be set
to frequencies higher than that of E1 and E2. The FOUT

The CS5466 supports input signals on the voltage and
current channels that may not be a sine wave. A typical
situation of achieving the absolute maximum frequency
on E1 and E2 would be if a 250 mV dc signal is applied
