Product Detail

12.5 Gbps Low Power Laser Driver and Limiting Amplifier with DC-DC Controller, EEPROM and Digital Diagnostics

The MALD-02194 is a low power, highly integrated, programmable laser driver and limiting amplifier intended for optical module applications to 12.5Gbps. An internal state machine and EEPROM perform all functions necessary for standalone operation. The internal state machine will acquire and scale industry standard monitoring parameters in real time and make them available to a MAC or external host controller.
