M02171
11.3 Gbps Dual Loop VCSEL Driver
Description
11.3 VCSEL Driver with OMA Control Offered in 5X5 mm 32-pin QFN Package
The M02171 is designed to drive vertical cavity surface emitting lasers used in transmitter optical sub-assemblies and supports data rates up to 11.3 Gbps. The M02171 supports both common anode and common cathode VCSEL configurations.
The M02171 features OMA control, which compensates for changes in laser slope efficiency over temperature and life. These features can also reduce or eliminate temperature calibration, thus improving system reliability and reducing overall cost. Integrated safety circuitry provides latched bias and modulation current shutdown if a fault condition is detected and provides either internal Vcc switch or ground switch.
Features
- Data rates to 11.3 Gbps. single 3.3 V supply
- OMA control for average optical power and modulation amplitude
- Programmable VCSEL bias current to 15 mA
- Programmable VCSEL modulation current to 15 mA
- Provides internal Vcc and ground switch for single point faults
- Input equalization for SFP+ requirements
- 2-wire or SPI serial interface available
