Introduction
The Intellon SSC P300 PL Network Interface Controller is a highly integrated power line transceiver and
channel access interface for implementing CEBus Standard compatible products. The SSC P300 provides
the Data Link Layer (DLL) control logic for EIA-600 channel access and communication services, a Spread
Spectrum Carrier (SSC) power line transceiver, signal conditioning circuitry, and an SPI compatible host
interface. A minimum of external circuitry is required to connect the SSC P300 to the power line. Superior
performance is achieved using the SSC P300 in conjunction with the SSC P111 Media Interface IC. The
SSC P300 is used with a host micro-controller to construct CEBus Standard compatible products and serves
as the basic communications element in a variety of low-cost power line networking applications.
The inherent reliability of SSC signaling technology and incorporation of basic data link functionality
combine to provide substantial improvement in network and communication performance over other power
line communication methods. The SSC P300 also makes an excellent low cost network interface for twisted
pair and DC power systems. A typical CEBus Standard power line node using the SSC P300 is illustrated
below.
