2 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, ADE7933/ADE7932, and ADE7923 Clocks section for more information.

Regulatory Approvals

The ADE7933/ADE7932 are approved by the organizations listed in Table 7. See Table 13 and the Insulation Lifetime section for more

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

Note that Table 13 presents the maximum working voltages for 50-year minimum lifetime: 400 V rms for ac voltages and 1173 V peak for

dc voltages. Greater working voltages shorten the lifetime of the product (see Insulation Lifetime section). Some certifications in Table 7

state greater maximum working voltages than the values presented in Table 13. Therefore, use the ADE7933/ADE7932 only for working

voltages lower than 400 V rms for ac voltages and 1173 V peak for dc voltages.

1 In accordance with UL 1577, each ADE7933/ADE7932 is proof tested by applying an insulation test voltage ≥ 6000 V rms for 1 sec (current leakage detection limit = 15 µA).

2 In accordance with DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, each ADE7933/ADE7932 is proof tested by applying an insulation test voltage ≥ 1590 V peak for 1 sec

(partial discharge detection limit = 5 pC). The asterisk (*) marking branded on the component designates DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 approval.

3 At this maximum working voltage, the approximate predicted lifetime is 0.2 years under 50 Hz, 60 Hz ac voltages.

4 At this maximum working voltage, the approximate predicted lifetime is 8 years under 50 Hz, 60 Hz ac voltages.
