DESCRIPTION

CLKIN
Master clock for ADCs and digital signal processing. An external clock can be pro-
vided at this logic input. Alternatively, a parallel resonant AT crystal can be connected
across CLKIN and CLKOUT to provide a clock source for the ADE7752. The clock
frequency for specified operation is 10MHz. Ceramic load capacitors of between 22pF
and 33pF should be used with the gate oscillator circuit. Refer to crystal manufacturers
data sheet for load capacitance requirements
A crystal can be connected across this pin and CLKIN as described above to provide a
clock source for the ADE7752. The CLKOUT pin can drive one CMOS load when
either an external clock is supplied at CLKIN or a crystal is being used.
These logic inputs are used to select one of four possible frequencies for the digital-to-
frequency conversion. This offers the designer greater flexibility when designing the
energy meter. See Selecting a Frequency for an Energy Meter Application section.
Low Frequency Logic Outputs. F1 and F2 supply
average real power
information. The
logic outputs can be used to directly drive electromechanical counters and two phase
stepper motors. See Transfer Function section.
