No. 2, Innovation Road II, Hsinchu Science Park, Hsinchu 300, Taiwan Tel: +886-3-5780211; Fax: +886-3-5776047 Realtek is ranked in the top 10 IC fabless design companies in the first half of 2020 according to TrendForce Fabless 2Q20 Ranking. Realtek’s Innovative Product Award winning RTL8156B new generation of USB Ethernet controller supports a 2.5Gbps connection speed and meets the power-saving specifications of various platforms and operating systems such as Modern Standby, Energy Star, EuP, and CEC. A major advantage of the RTL8156B is ease of roll-out; the 2.5Gbps speed can be achieved over legacy CAT-5e cabling that is already in place, which is the simplest solution for customers to upgrade their connection speed. The RTL8156B adopts a QFN56 package with a chip size of 6x6mm. It is the smallest packaged chip among USB 2.5Gbps Ethernet controllers in the market. Its small footprint means it can be used in laptop accessories such as USB dongles or expansion docks. Products utilizing the new RTL8156B will be launched in 2H 2020, and are expected to bring great advantages to our customers in promoting the easy upgrade option to 2.5Gbps speeds over existing CAT-5e network cabling. “Realtek has consistently developed innovative and well-received products in the years since its establishment”, said Realtek’s Vice President and Spokesman, Yee-Wei Huang. “We are honored to receive the 2020 Hsinchu Science Park R&D Accomplishment Award and Innovative Product Award, and welcome this recognition of Realtek's persistence in product/technology R&D and innovation”.
