General Description
The DS1864 is an SFF-8472 multisource agreement (MSA)-compliant laser controller/monitor that is ideal for SFP optical-transceiver module designs.
It controls laser driver bias and modulation currents through a pair of temperature-controlled current-sink DACs.
Key Features
- are integrated by three fast-trip comparators that monitor transmit-power high, transmitpower low, and bias current. The fast-trip comparators drive a FET driver output to disable the laser in the case of eye safety violation. With its integrated laser driver control, system diagnostics, eye-safety features, and internal temperature sensor, the DS1864 provides an ideal solution for SFP optical transceiver modules by improving system performance, reducing board space, and simplifying design.
