MACOM launches low-power quad-channel 28Gbps laser drivers for 100GbE CFP2, CFP4 and QSFP28 modules

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) has announced additions to its portfolio of drivers for 100 Gigabit Ethernet (100GbE) applications.

The MAOM-003401 is a quad-channel 28Gbps electro-absorption modulator laser (EML) driver that can deliver up to 1.6Vpp single-ended output while dissipating less than 230mW of power per channel. When paired with MACOM’s M37049 quad-channel clock & data recovery (CDR) IC, it provides what is claimed to be the lowest-power and smallest-form-factor solution on the market for CFP2 and CFP4 transceivers. A demonstration of the full optical transmitter line-up with CDR, driver and TOSA (transmitter optical subassembly) will be on display in booth 2203 at the Optical Fiber Communication conference & exposition (OFC 2014) in San Francisco (11-13 March).

The MAOM-002304 is a quad-channel 28Gbps direct modulated laser (DML) driver that can deliver up to 70mA of laser bias current and 60mA of modulation current with less than 240mW of power dissipation per channel. The single-die solution can be integrated in a TOSA and directly DC coupled to the laser, minimizing losses and maximizing efficiency. The device can also be paired with the M37049 low-power CDR to meet the stringent power requirements of QSFP28 modules.

“MACOM can continue to push the limits on power dissipation with these new products,” says Optoelectronics product line manager Ray Moroney. “With the addition of CDRs and TIAs [transimpedance amplifiers] from former Mindspeed [acquired earlier this year], MACOM can continue to innovate and integrate to provide optimized solutions.”

Samples of the MAOM-003401 and MAOM-002304 are available now.
