(V Pkg.)
Type
Function
AD0–AD3
8–11
O
A/D Digital Output:
These signals are the ones complement digital output of the signal
received from the power line. It is the output of the flash A/D sampled at the AD CLK rate.
AD CLK
12
I
Clock For The Flash A/D Converter:
This is the clock used by the A/D converter to sample
the signal received from the power line. It is normally 1 MHz and is generated by the digital
ASIC.
DGND

I
Square Wave Transmit Signal:
This is the Manchester-encoded, frequency mixed signal
3F
15
I
Third Harmonic Overtone Cancellation Signal:
This is the third harmonic overtone
cancellation signal used to convert FSQWV to a sine wave in the Analog chip D/A
5F
16
I
Fifth Harmonic: Overtone Cancellation Signal:
This is the fifth harmonic overtone
cancellation signal used to convert FSQWV to a sine wave in the Analog chip D/A
7F
17
I
Seventh Harmonic: Overtone Cancellation Signal:
This is the seventh harmonic overtone
cancellation signal used to convert FSQWV to a sine wave in the Analog chip D/A
DRV EN
18
I
Drive Enable:
This is the transmit enable signal used by the Analog chip to disable the
receiver mode and enable the transmitter mode
VEED

O
Digital To Analog Converter Integrator Output:
This is the analog output of the D/A
converter integrator
WVIN
21
Digital To Analog Converter Integrator Input:
This is the analog input of the D/A converter
integrator. It is connected internally to the D/A converter output. It is used to connect the
external integrator capacitor to the integrator input.
