GENERAL DESCRIPTION
The VSC7964 is a multirate 4.25 Gbps integrated Vertical Cavity Surface Emitting Laser (VCSEL) driver and limiting amplifier for Gigabit Ethernet and Fibre Channel applications optimized to reduce SFP module cost. A standard SPI port is provided for programming integrated digital-to-analog converters for laser bias current, modulation current, power, modulation peaking current, and the limiting amplifier loss of signal threshold. The VSC7964 is equipped with SFP-compliant fault indicators, redundant disable control, Automatic Power Control, temperature sensor, voltage reference, various signal monitors, and robust eye safety features.
