DESCRIPTION
The SY88922V 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.

FEATURES
■ 3.3V and 5V power supply options
■ Up to 2.5Gbps operation
■ 30mA modulation current
■ Separate modulation control
■ Separate output enable for laser safety
■ Differential inputs for data
■ 75KΩ input pulldown resistor
■ Available in a tiny 10-pin (3mm) MSOP

APPLICATIONS
■ 1.25Gbps and 2.5Gpbs Gigabit Ethernet
■ 531Mbps, 1062Mbps and 2.12Gbps Fibre Channel
■ 622Mbps SONET
■ Gigabit Interface Converter
■ 2.5Gbps SDH/SONET
■ 2.5Gbps Proprietary Links
