New TIAs and drivers optimize performance in data centers and client-side operations

    GREENSBORO, NC – March 16, 2017 – Qorvo® (Nasdaq:QRVO), a leading provider of innovative RF solutions that connect the world, has introduced five new low-power pulse amplitude modulation-4 (PAM4) optical solutions. The new products connect equipment inside data centers to efficiently process and deliver ever-increasing volumes of data. The family of transimpedance amplifiers (TIAs) and drivers gives customers the broadest range of PAM4 options to support the needs of 100G to 400G optical networks.

    “While the current ramp of 100G Ethernet in large data centers is dramatic, there is considerable interest in implementing the new Ethernet speeds, especially with PAM4 modulation,” remarked Vladimir Kozlov, founder and CEO of LightCounting Market Research. “Qorvo’s new linear drivers and TIAs will support all the new speeds from 25G, 50G, 200G and even 400G.”

    Gorden Cook, general manager of the Qorvo Transport Business Unit said, “We are excited to launch the industry’s broadest PAM4 product line, including both drivers and TIAs. These products are designed to more efficiently connect equipment in data centers and client-side telecom applications. Our complete range of solutions will enable our optical customers to improve performance, reduce total cost and accelerate the implementation of 100G to 400G systems.”

    Built on high-performance gallium arsenide (GaAs), indium phosphide (InP) and silicon germanium (SiGe) technologies, the Qorvo PAM4 family includes three 28GBaud linear drivers and two linear TIAs. The units feature the industry’s leading power efficiency within the range of 200 milliwatts per channel, high gain and high linearity, in a small footprint.

    Qorvo’s new linear drivers are now being built into optical network systems. The single-channel TIAs will be available for sampling in April. Additional quad-channel drivers and new TIAs will be available in late 2017.
