Introduction
The SSC P111 PL Media Interface IC provides the functions of Output Power Amplifier and Output Tri-state Switch for power line transceiver products. The Output Power Amplifier meets the requirements specified by the EIA-600 (CEBus Standard) for output
voltage levels into typical and low impedance power line loads and incorporates over-temperature protection for improved system reliability. The IC replaces approximately 30 of the discrete components normally used in support of PL transceivers and reduces required printed circuit board area by up to 50%.
