Appendix A – PL Smart Transceiver Reference Designs
216 PL 3120/PL 3150/PL 3170 Power Line Smart Transceiver Data Book
Introduction
This appendix describes the implementation of the external, discrete interface circuitry for the PL 3120, PL 3150 and
PL 3170 Smart Transceivers. The interface circuitry includes the front-end filter for the receiver and the power amplifier
for the transmitter. The interface is comprised of roughly fifty components, primarily resistors and capacitors. Echelon
provides a comprehensive PL Development Support Kit (DSK) for implementing the interface circuitry. The section
that follows lists the contents of the DSK. Contact your Echelon salesperson to purchase the DSK.
A variety of reference designs are provided with the DSK to address applications requiring different numbers of printed
circuit board (PCB) trace layers, single- or double-sided component assembly, various aspect ratios, and transmit current
requirements. Each PL Smart Transceiver reference design package consists of a zip archive file that contains all of the
relevant files for that design. The naming convention used for these zip files is shown in the figure below.
