MAX3654: Obtaining Larger Output Signals in GPON ONT Video Overlay Applications Using the MAX3654
Aug 17, 2010
Abstract: The MAX3654 is an easy to use, low-cost solution to the AGC amplifier block; however depending on the system parameters (Optical modulation Index (OMI), average optical power, number of channels, etc.) additional gain may be needed. This application note provides background information on the need for increased gain, and illustrates a method for obtaining larger output amplitude, while maintaining the critical system requirements, using a post amplifier. Schematics and test data are also provided.
