SY88922 Datasheet | Micrel Semiconductor

Micrel, Inc. SDH/SONET 2.5Gbps LASER DIODE DRIVER Features DESCRIPTION - Up to 2.5Gbps operation - 25mA peak drive current - Separate modulation control - Separate output enable for laser safety - Differential inputs for data - 75KΩ input pulldown resistor - Designed for use with SY88923, SY88904 or SY88905 - Available in a tiny 10-pin (3mm) MSOP The SY88922 is a high-speed current switch for driving a semiconductor laser diode in optical transmission applications. The output current, or modulation current IMOD, is DC current controlled by IRSET, current through the resistor RSET. The output OUT is HIGH when output enable is HIGH. The device incorporates plementary...
