Part Details
- 50 Mbps to 3.3 Gbps operation
- Single 3.3 V operation
- Typical rise/fall time: 80 ps
- Bias current range: 2 mA to 100 mA
- Modulation current range: 5 mA to 80 mA
- Monitor photodiode current: 50 µA to 1200 µA
- Dual MPD functionality for DWDM
- 50 mA supply current at 3.3 V
- Closed-loop control of power and extinction ratio
- Full current parameter monitoring
- Laser fail and laser degrade alarms
- Automatic laser shutdown (ALS)
The ADN2847 uses a unique control algorithm to control both average power and extinction ratio of the laser diode (LD) after initial factory setup. External component count and PCB area are low, as both power and extinction ratio control are fully integrated. Programmable alarms are provided for laser fail (end of life) and laser degrade (impending fail).
Optional dual MPD current monitoring is designed into the ADN2847 specifically for DWDM wavelength control.
The ADN2847 is specified for the −40°C to +85°C temperature range and is available in a 48-lead LFCSP package and a 32-lead LFCSP package.
APPLICATIONS
- SONET OC-1/3/12/48
- SDH STM-0/1/4/16
- Fibre Channel
- Gigabit Ethernet
- DWDM dual MPD wavelength control
