Router Chip Delivers Speed To IoT And Smarthome


Broadcom announced the industry’s first 64bit quad-core processor for high-end routers. The BCM4908 delivers high CPU power needed for smarthome and Internet of Things applications while unleashing the higher Internet speeds coming into the home.

The BCM4908 includes a 1.8GHz ARM CPU together with a Broadcom’s Runner network packet processor to deliver more than 5 Gbps of system data throughput. It also supports the increased speeds coming into the home including Google Fiber and Comcast 2 Gbps via an interface for a 2.5 Gigabit Ethernet PHY, allowing consumers to enjoy the fastest connection available today, the company says.

“With this new SoC, Broadcom is driving home network connectivity to the next level,” said Manny Patel, Broadcom Director of Marketing, Wireless Connectivity. “By increasing the CPU performance and adding advanced features, we’re enabling OEMs to build more powerful home routers that address the increased bandwidth requirements needed to support the continued consumption of high-bandwidth content, growing demand for UltraHD as well as the growing emergence of more IoT and smart home applications.”


The routers can achieve more than 3.4Gbps of combined speed when paired with the company’s BCM4366 wave 2 5G WiFi MU-MIMO chip. Utilizing low power 28nm technology and advanced power management, power reductions of more than 50 percent are achieved as compared to previous solutions.

Further, the router supports 5G WiFi 802.11ac MU-MIMO, three BCM4366 4×4 radios, each with an integrated CPU for host offload processing, to provide seven CPU cores with more than 9.6 GHz of CPU horse power.

Further, a 2.5Gb Base-X Ethernet WAN/LAN port is also provided for supporting multi-gigabit modem or a Network Attached Storage (NAS) device.
