Hardware Description
The high voltage PLC evaluation Board is shown in
The low voltage section (top half in
coupling transformer and the power supply's isolation transformer. The board is divided into four
main sections:

The communication signal flow on this HV board is:
Transmit: CY8CPL10 TX pin → Transmitter filter circuitry → Power amplifier circuitry → High volt-
age powerline coupling circuitry → High voltage powerline (110 V to 240 V AC)
Receive: High voltage powerline (110 V to 240 V AC) → High voltage powerline coupling circuitry →
Passive low pass filtering → Vdd/2 biasing → CY8CPLC10 RX pin
The core of the PLC HV board is the CY8CPLC10 chip. The board contains an I2C connector, jump-
ers to control various functions, and a five-position DIP switch.
