MACOM MAOM-002304 Quad Channel Direct Modulated Laser Driver IC

March 17, 2015
Large data centers are asking for low-power, low-cost 100G modules in a QSFP28 form factor for 2 km. Directly modulated lasers (DMLs) are better suited than externally modulated lasers (EMLs) for meeting the power dissipation requirements of QSFP28.
With a power dissipation of only 240 mW per channel this monolithic quad DML driver provides the low power dissipation necessary for transceiver manufacturers to meet the requirements of next-generation form factors such as QSFP28. Judge's Comment.
Large data centers are asking for low-power, low-cost 100G modules in a QSFP28 form factor for 2 km. Directly modulated lasers (DMLs) are better suited than externally modulated lasers (EMLs) for meeting the power dissipation requirements of QSFP28. But, DMLs require drivers that can output a modulated current. MACOM's MAOM-002304 is a modulated quad-channel DML driver that dissipates less than 240 mW per channel, including 70 Ma of laser bias current. In addition to low power consumption, the MAOM-002304 can be bonded to the laser without additional biasing components. This reduces the PCB area and simplifies assembly, MACOM says.
