描述
The LTC?5100 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 LTC5100 has a precisely controlled 50 Ohm 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 LTC5100 confines the modulation current to the ground system, isolating the high speed signal from the power supply to minimize RFI.
The LTC5100 supports fully automated production with its extensive monitoring and control features. Integrated 10-bit DACs eliminate the need for external potentiometers. An onboard 10-bit ADC provides the laser current and voltage, as well as monitor diode current and temperature. Status information is available from the I2C serial interface for feedback and statistical process control.
An internal digital controller compensates laser temperature drift and provides extensive laser safety features.
