The VSC7965 is a multirate 1.25 Gbps integrated laser driver and limiting amplifier for Passive Optical Network applications optimized to reduce module cost. The device is intended to drive distributed feedback (DFB) and Fabry Perot (FP) lasers. A standard SPI port is provided for programming integrated digital-to-analog converters for laser bias current, modulation current, average power, and the limiting amplifier loss of signal threshold. The VSC7965 is equipped with SFP-compliant fault indicators, redundant disable control, Automatic Power Control, temperature sensor, various signal monitors, and robust eye safety features. The VSC7965 is available in a 5mm x 5mm 32-pin QFN plastic package.
