The pulse output frequency of E1 is directly proportional
to the active power calculated from the input signals. To
calculate the output frequency of E1, the following trans-
fer function can be utilized:
With MCLK = 4.096 MHz and default settings, the puls-
es will have an average frequency equal to the frequen-
cy specified by PulseRate when the input signals
applied to the voltage and current channels cause
full-scale readings in the instantaneous voltage and cur-
rent registers. The maximum pulse frequency from the

With MCLK = 4.096 MHz, PF = 1, and default settings,
the pulses will have an average frequency equal to the
frequency specified by PulseRate when the input sig-
nals applied to the voltage and current channels cause
full-scale readings in the instantaneous voltage and cur-
rent registers. The maximum pulse frequency from the
E1 pin is (MCLK/K)/2048.
5.5.2 Apparent Energy Mode
Pin E2 outputs apparent energy pulses when the Oper-
rection indicator.
5.5.3 Reactive Energy Mode
Reactive energy pulses are output on pin E3 by setting
bit E3MODE[1:0] = 0 (default) in the Operational Mode
Register . Positive reactive energy is registered by E3
falling when E 2 is high. Negative reactive energy is reg-
istered by E3 falling when E2 is low. Figure 5 on
page 17 illustrates the pulse output format with negative
reactive energy output on pin E3 and the sign of the en-
ergy on E2. The E3 and E2 pulse output switching char-
acteristics are specified in Figure 2 on page 13.
The pulse output frequency of E3 is directly proportional
to the reactive power calculated from t he input signals.
To calculate the output frequency on E3, the following
transfer function can be utilized:
VIN ? VGAIN ? IIN ? IGAIN ? PQ ? PulseRate

The pulse output frequency of E2 (and/or E3) is directly
proportional to the apparent power calculated from the
input signals. Since apparent power is without reference
to an impedance phase angle, the following transfer
function can be utilized to calculate the output frequency
on E2 (and/or E3).
