ADE7753 ERRATA (REV 1.0)
The following is a list of known issues with the first revision
of the ADE7753 silicon (rev 1.0). These issues will be
resolved in the next version. Samples of this version of the
silicon can be identified from the content of the DIEREV
regsiter (Address 3Fh). The content of DIEREV register is
2 for Rev 1.2 silicon. In addition, the branding on top of the
package for Rev 1.2 should be as shown below:
ERRATA
1. SAGCYC
The contents of SAGCYC register is equivalent to
(SAGCYC-1).
linecycles for SAG detection is 20d line cycles, one should
write 21d to the SAGCYC Register. This is not a silicon
bug.
2. CFNUM and CFDEN
CFNUM should always be less than CFDEN. The behav-
ior of the output frequency is not guaranteed for CF. This
is not a silicon bug.
For example, if the desired number of
