Preliminary Technical Data
TIMING SPECIFICATIONS
AC inputs during testing are driven at V
and 0.45 V for Logic 0. Timing measurements are made at V
minimum for Logic 1 and V
Figure 2.
For timing purposes, a port pin is no longer floating when a
100 mV change from load voltage occurs. A port pin begins to

The ADE7566/ADE7569 internal PLL locks onto a multiple (512 times) of the 32.768 kHz external crystal frequency to provide a stable 4.096 MHz internal clock for the
system. The core can operate at this frequency or at a binary submultiple defined by the CD[2:0] bits, selected via the POWCON SFR.
