MACOM launches chipset for QSFP28 modules for data-center applications

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has announced availability of its complete chipset for CWDM and PSM4 applications in the data-center. The chipset includes the complete lineup of electronic and optical integrated circuits to achieve the lowest power consumption in a QSFP28 form factor.

As new mega-datacenters continue to expand to service the demand for high-speed data communications, the volume of 100G transceivers is expected to grow exponentially with the parallel need for lower-power, smaller-size and lower-cost components. MACOM has consolidated the high-speed semiconductor content in 100G transceivers and now offers the complete solution including lasers, drivers, CDRs (clock & data recovery) and TIAs (transimpedance amplifiers) – all optimized to provide highly differentiated performance, power, size and cost benefits.

The M37046 and M37049 are claimed to be the lowest-power and smallest quad-channel receive and transmit CDRs. The MAOM-002301 and MAOM-002304 are single- and quad-channel directly modulated laser (DML) drivers that offer what is claimed to be the lowest-power solution in the market. They are also said to be widely adopted in the market due to ease of assembly inside the transmitter optical sub-assembly (TOSA). In addition, the 127/129/131/133D-25C-LCG11 family of distributed feedback (DFB) lasers covers CWDM and PSM4 wavelengths, offering high performance over a broad operating temperature range. The M03002 and M03102 are single- and quad-channel TIAs offering what is claimed to be the industry's lowest noise and power consumption for 28G applications. The bundle is fully supported by MACOM's expert applications team to provide faster time to market for transceiver designers. Economies of scale also provide significant cost benefit to manufacturers building transceivers based on the MACOM chipset, the firm reckons.

"By providing the complete solution in a neat bundle, we can provide cost and power efficiency benefits which solve our customers' high-speed networking challenges," says Vivek Rajgarhia, MACOM's VP of strategy, Networks. 

All of the products in MACOM's 100G data-center bundle are now shipping in volume.
