VSC7964 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. A single bidirectional pin between the VSC7964 and the VSC7977 transimpedance amplifier programs the receiver bandwidth and monitors the received optical power. This allows the VSC7964 to provide an accurate indicator of received power and to select the TIA bandwidth without increasing TO-CAN pin count. The VSC7964 is available in a 6mm x 6mm 40-pin QFP-N plastic package.
