PLC LV Evaluation Board
3.1
Features
The key features of the CY3273 evaluation board are:
■
Chip power supply derived from 12 V to 24 V AC/DC
■
On-chip powerline network protocol layer and physical layer FSK modem
■
LED status indicators for power, powerline transmit and receive, and band in use
■
Five-position DIP switches
❐
Three DIP switches for node logical address selection
❐
One DIP switch to configure node I
2
C addressing mode
❐
One DIP switch to select between the external crystal and oscillator
■
Integrated powerline modem PHY

Functional Overview
The PLC evaluation board is designed as an advanced evaluation, testing, and product development
platform for low bandwidth (2400 bps) powerline communication.
Data to be transmitted is sent to the CY8CPLC10 through the I
2
C serial communications interface
from a host microcontroller.
The CY8CPLC10 receives this I
2
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.
