Like the ADN2870, the ADN2872 laser diode driver is designedfor advanced SFP and SFF modules, using SFF-8472 digitaldiagnostics. The device features dual-loop control of the averagepower and extinction ratio (ER), which automatically compensatesfor variations in laser characteristics over temperature and aging.The laser needs only be calibrated at 25°C, eliminating the needfor expensive and time consuming temperature calibration. TheADN2872 supports single-rate operation from 50 Mbps to3.3 Gbps, or multirate operation from 155 Mbps to 3.3 Gbps.With a new alarm scheme, this device avoids the shutdown issuecaused by the system transient generated from various lasers.
The average power and ER can be set with a voltage provided bya microcontroller digital-to-analog converter (DAC) or by atrimmable resistor. The device provides both bias and modulationcurrent monitoring, as well as fail alarms and automatic lasershutdown. The ADN2872, a SFF-/SFP-compliant laser diode driver,can work with the Analog Devices, Inc., ADuC7019, ADuC7020,and ADuC7023 MicroConverter® family and the ADN2890,ADN2891, and ADN2892 limiting amplifier family, to form acomplete SFP/SFF transceiver solution. The ADN2872 is availablein a space-saving 4 mm × 4 mm LFCSP specified over the−40°C to +85°C temperature range.
