Introduction
The Intellon SSC P485 PL Transceiver IC is a highly integrated spread spectrum communication transceiver for
implementing low-cost networking products. The SSC P485 contains a Spread Spectrum Carrier鈩?(SSC)
transceiver, signal conditioning circuitry, and a simple host interface. A minimum of external circuitry is required
to connect the SSC P485 to the DC power line, twisted pair cable, or other communication medium.
The inherent reliability of SSC signaling technology provides substantial improvement in network and
communication performance over other low-cost communication methods. The SSC P485 is the ideal basic
communications element for a wide variety of low-cost networking applications.
