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 ponents normally used in support of PL transceivers and reduces required printed circuit board area by up to 50%.

The output waveform is amplified by the Power Amplifier and then applied to the external Power Line Coupling/Filter network. Received power line analog signals pass through the external power line Coupling/Filter network to the Input Filter. This bandpass filter passes the chirp frequency band (100 to 400 k Hz) to the SSC P300 or P200 SI input pin. The Tri-state (TS)...
