See the Terminology section for definitions of the parameters.

XTAL1/XTAL2 total capacitances refer to the net capacitances on each pin. Each capacitance is the sum of the parasitic capacitance at the pin and the capacitance of

the ceramic capacitor connected between the pin and GND. See the ADE7978 and ADE7933/ADE7932 Clocks section for more information.

Regulatory Approvals (Pending)

The ADE7933/ADE7932 are pending approval by the organizations listed in Table 7. See Table 12 and the Insulation Lifetime section for

more information about the recommended maximum working voltages for specific cross-isolation waveforms and insulation levels.
