DS1864 - SFP Laser Controller and Diagnostic IC
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.
System diagnostics are provided by moni
DS1864 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
