Functional Overview
The PLC evaluation board is designed as an advanced evaluation, testing, and product development
platform for low bandwidth (2400 bps) powerline communication.
2
Data to be transmitted is sent to the CY8CPLC10 through the I C serial communications interface
from a host microcontroller.
2
The CY8CPLC10 receives this I C data and encapsulates it into a PLC network packet. The on-
board FSK modem modulates this packet and the coupling circuitry incorporates the resulting
sinusoidal waveform on to the existing waveform on the high voltage powerline bus.
