Broadcom Corporation has introduced new 5G Wi-Fi system-on-a-chips (SoCs) for connected home devices. The BCM43569 and BCM43602 enable OEMs to deliver the speed, range and bandwidth requirements for streaming HD-quality content, online gaming and other high-bandwidth applications in the home.

Consumers are streaming video content to multiple devices in the home using various applications and content delivery services. Legacy technologies limit the ability to support the evolving bandwidth and Quality of Service (QoS) needed for the intensive connected home lifestyle. For example, using Bluetooth- and Wi-Fi-enabled devices such as remotes, speakers and game controllers can reduce available Wi-Fi bandwidth and cause interference when playing an online game or streaming a movie from a tablet to a smart TV. The BCM43569 is the industry’s first dual-band 2x2 MIMO combo chip with a USB 3.0 interface and advanced coexistence technology that enables superior performance by allowing smart TVs to receive both Wi-Fi and Bluetooth signals simultaneously.

Routers, gateways and set-top boxes rely heavily on the platform’s host CPU processing power to deliver HD content over 5G WiFi to multiple devices in the home. Broadcom’s BCM43602, a new 3x3 MIMO 802.11ac SoC solution, enables these platforms to offload Wi-Fi processing from the host processor to deliver the benefits of 5G Wi-Fi to the consumer. Combined, the new chips deliver the speed, power and range requirements needed around the home to support consumer demand for content anywhere and anytime. Beamforming is also supported on both chips to ensure whole-home wireless coverage.

Key Features and Benefits:

· The BCM43569 is a dual-band 2x2 MIMO combo chip (5G WiFi and Bluetooth 4.1) for media platforms such as digital televisions and over-the-top media boxes. Highlights include:

Industry’s first chip to include a common USB port for Wi-Fi, Bluetooth and integrated Power Amplifiers (iPA) across both bands, significantly reducing system cost and enabling OEMs to offer connectivity on more platforms

Delivers 3X bandwidth for seamless streaming or gaming

Separate Bluetooth low-noise amplifier (LNA) coupled with customized Wi-Fi and Bluetooth coexistence algorithms allow Bluetooth gaming, audio and motion peripherals to perform in challenging environments

Broadcom Media Stack (BMS) enables innovative connectivity software features like TVSelect, audio over Wi-Fi, seamless gaming and Miracast for a rich DTV experience

Interface: USB 3.0 and USB 2.0

· The BCM43602 is a 3x3 MIMO 802.11ac chip designed for access/DSL/Cable/STB platforms. Highlights include:

Ability to achieve full 802.11ac (900 Mbps TCP) throughput on CPU constrained systems

Simplified WLAN software integration with host

Entire WLAN driver runs inside of the BCM43602, freeing up host CPU for applications such as video streaming

Pin-compatible, drop in and full feature replacement to Broadcom’s industry leading BCM4360, in production across multiple retail and service provider customers

Ability to enable low power standby modes

Interface: PCIe

Availability

The BCM43569 and BCM43602 are now sampling.
