High Voltage Section with SMPS
This section gets power from the powerline and generates necessary low DC voltage for the opera-
tion of the PLC transceiver and other components on the chip.
Table 2-1. Key High Voltage with SMPS Components
Transmit Amplifier and Filtering Section
This section takes the output signal from the transceiver chip. The circuit amplifies the signal and fil-
ters it for compliance purposes only. The amplification is to drive the signal on long cables or in low
impedance networks. Filtering is done in three stages.
Table 2-2. Key Transmit Amplifier and Filtering 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 into the board rejecting the actual 50 and 60 Hz powerline
signal. The isolation transformer in the circuit is required for safety.

RJ45 Connector for Debugging
This is the two pin connector where the AC cable hooks up to the powerline.
Protection fuse for the circuit.
Full wave bridge rectifier diode IC.
Common mode choke.
iW1690-07 – iWatt high performance AC/DC power supply controller.
Flyback transformer.
5V regulator.
These opamps are used to filter the signal from the CY8CLED16P01 removing the harmon-
ics. The filter stages are only required to meet the European CENELEC EN50065-1:2001
signaling specification. They are not required to achieve robust PLC communication.
These opamp and high gain transistors are used for the power amplification stage.
This is the isolation transformer which provides isolation between the HV and LV sections of
the board. It is 1:1 ratio transformer.
This is the coupling capacitor which couples the communication signal and rejects the low
frequency noise. The voltage and X1 safety rating of this component are important parame-
ters.
