3.3 V, Dual Loop, 50 Mbps to 3.3 Gbps Laser Diode Driver
Average power and extinction ratios can be set with reference voltages provided by a microcontroller DAC or by adjustable resistors. The ADN2870 provides bias and modulation current monitoring as well as fail alarms and automatic laser shutdown. The device interfaces easily with the ADuC702x family of MicroConverters® and with the ADN289x family of limiting amplifiers to make a complete SFP/SFF transceiver solution. An SFP reference design is available. The product is available in a space-saving 4 mm × 4 mm LFCSP specified over the −40°C to +85°C temperature range.
