3.0V to 5.5V, 1.25Gbps/2.5Gbps LAN Laser Drivers
General Description
The MAX3286/MAX3296 series of products are highspeed laser drivers for fiber optic LAN transmitters optimized for Gigabit Ethernet applications. Each device contains a bias generator, laser modulator, and comprehensive safety features. Automatic power control (APC) adjusts the laser bias current to maintain average optical power at a constant level, regardless of changes in temperature or laser properties. For lasers without a monitor photodiode, these products offer a constant-current mode. The circuit can be configured for use with conventional shortwave (780nm to 850nm) or longwave (1300nm) laser diodes, as well as verticalcavity surface-emitting lasers (VCSELs).
The MAX3286 series (MAX3286–MAX3289) is optimized for operation at 1.25Gbps, and the MAX3296 series (MAX3296–MAX3299) is optimized for 2.5Gbps operation. Each device can switch 30mA of laser .
