CLKIN FREQUENCY
In this data sheet, the characteristics of the ADE7763 are shown
when CLKIN frequency equals 3.579545 MHz. However, the
ADE7763 is designed to have the same accuracy at any CLKIN
frequency within the specified range. If the CLKIN frequency is
not 3.579545 MHz, various timing and filter characteristics will
need to be redefined with the new CLKIN frequency. For
example, the cutoff frequencies of all digital filters, such as
LPF1, LPF2, or HPF1, shift in proportion to the change in
CLKIN frequency according to the following equation:
transfer—see the timing characteristics in Table 2. Table 8 lists
various timing changes that are affected by CLKIN frequency.
