ADI LTC5100EUF#TRPBF

Драйвер лазерного диода3,2 Гбит/с3.135V ~ 3.465V

Overview

The LTC5100EUF is a 3.2Gbps VCSEL driver offering an unprecedented level of integration and high speed performance. The part incorporates a full range of features to ensure consistently outstanding eye diagrams. The data inputs are AC coupled, eliminating the need for external capacitors. The LTC5100EUF has a precisely controlled 50Ω output that is DC coupled to the laser, allowing arbitrary placement of the IC. No coupling capacitors, ferrite beads or external transistors are needed, simplifying layout, reducing board area and the risk of signal corruption. The unique output stage of the LTC5100EUF confines the modulation current to the ground system, isolating the high speed signal from the power supply to minimize RFI.

An internal digital controller compensates laser temperature drift and provides extensive laser safety features.
