MAX3265: Using MAX3265 LOS in GBICs

Abstract: The gigabit interface converter (GBIC) is a compact transceiver for high-speed data communications. The receiver portion of an optical GBIC provides a loss-of-signal (LOS) indication. The MAX3264, MAX3265, MAX3268 and MAX3269 are limiting amplifiers with LOS that are well suited for use in GBIC modules. This design note describes a method that ensures reliable LOS operation under all operating conditions.
