Single Channel 28 Gbps Direct Modulated Laser Driver IC

The MAOM-002301 is a compact, highly integrated single channel Direct Modulated Laser (DML) driver IC for 100 Gbps optical module applications. The MAOM-002301 is driven with a 700 mVpp differential input signal and provides a modulation output current that can be controlled from 10 mApp to 60 mApp. The driver is available in die form and can be wire bonded directly to the laser with no external chokes required. DML bias current (Ibias) can be controlled over a range of 20 to 70 mA. Total power consumption including a DML bias current of 50 mA is typically 255 mW.
