Power Supply Circuit
This section takes the power from the powerline and generates the necessary low DC voltage for the
operation of the PLC transceiver and other components on the chip.
Table 2-1. Key Power Supply Circuitry Components
Transmit Amplifier Circuit
This section takes the output signal from the CY8CPLC20 chip and amplifies the signal for transmis-
sion over the powerline.
Table 2-2. Key Transmit Amplifier Components
Transmit and Receive Coupling Circuit
This circuit couples the signal from the board on to the powerline. On the receive side, the same cir-
cuit couples the carrier on the powerline in to the board rejecting the low frequency content on the
powerline.

This is the connector to hook up the wall wart
5V regulator
This is a 2 pin header to connect other boards in daisy chain and power them.
The cable to do this is provided with the kit. Connect a maximum of five boards
in one daisy chain.
This is a blue LED which is on when power is supplied to the board
These opamp and high gain transistors are used for power amplification.
This transistor controls whether transmission is allowed based on the out-
put of the TXDISABLE pin
This inductor along with R2 filters out the higher frequencies
This is the inductor which grounds the low frequency signal and forms a high pass
with C1 and L1
This is the coupling capacitor that couples the communication signal and rejects
the low frequency noise. The voltage rating of this component is an important
parameter.
