M02172
11.3 Gbps EML Driver
Description
The M02172 is designed to drive Electroabsorption Modulated Lasers (EML) with a 50 ohm characteristic impedance used in transmitter optical sub-assemblies. In EML applications, the programmable offset adjustment is integrated into the signal output. Output bias (offset) voltage which varies linearly as a function of temperature is provided as required by some EML devices.
The M02072 combines a diagnostic monitoring interface compliant with XFP, or SFP+ and a EML driver in a compact 5 mm x 5 mm QFN package. Integrated safety circuitry provides latched bias current and modulation voltage shutdown if a fault condition is detected. The device comes with firmware required for diagnostic monitoring, offering a seamless interface for calibration and setup.
Features
- Data rates to 11.3 Gbps. single 3.3 V supply
- Programmable laser bias current to 150 mA
- Programmable laser modulation voltage to 2.5 Vpp
- SFP/XFP compliant safety circuitry
- Provides internal Vcc switch for single point faults
- Supports both CA and CC laser configurations
