GENERAL DESCRIPTION
The ADN2848 uses a unique control algorithm to control both
the 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).
FEATURES
50 Mbps to 1.25 Gbps Operation
Single 3.3 V Operation
Bias Current Range 2 mA to 100 mA
Modulation Current Range 5 mA to 80 mA
Monitor Photo Diode Current 50 A to 1200 A
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
Optional Clocked Data
Supports FEC Rates
32-Lead (5 mm
