STMicroelectronics Releases New Set-Top-Box SOC with Integrated Wi-Fi


Cost-effective, highly integrated, and power-optimized Cannes Wi-Fi SoC enables large-scale deployment of HD-Video Clients and Interactive STBs


STMicroelectronics has released its Cannes Wi-Fi (STiH390) System-on-Chip, targeting HD HEVC Wi-Fi® IP client and interactive set-top-box markets.

Customers expect to get flawless experiences at home when watching their favorite TV content on smartphones, tablets, and set-top-boxes using their wireless networks. Coverage limitations create frustration and restrict the potential for services provided over Wi-Fi, leading Multiple Service Operators (MSO) to look for cost-effective and flexible solutions that are easy to install and enable uncompromised multi-room multimedia services.

Addressing the need for economical high-quality HD video within the whole home, ST has joined forces with Quantenna to create the Cannes Wi-Fi (STiH390) SoC. The new chipset integrates Quantenna's proven Wi-Fi 802.11 IP with ST's latest-generation HD HEVC SoC to push down cost without compromising on performance.

“We expect this breakthrough solution to become a reference HD video-over-Wi-Fi solution that advances large-scale deployment of powerful and affordable Wi-Fi IP clients,” said Philippe Notton, Group Vice President and General Manager of STMicroelectronics Consumer Product Division. “With the Cannes Wi-Fi SoC, we have optimized the integration of Quantenna's Wi-Fi 802.11 IP for both cost and speed and we've validated and confirmed its exceptional performance on new and existing video-distribution use cases to fully leverage the latest Wi-Fi 802.11 ac features.”

“We are delighted to see ST be first to market with a set-top-box SoC integrating 4x4 11ac Wi-Fi. This is the first ST product to include Quantenna's digital baseband IP enabling the next level of silicon integration that customers want,” said Lionel Bonnot, Senior Vice President of Marketing and Business Development at Quantenna. “This baseband supports 4x4 802.11ac/11n wave2, delivering state-of-the-art Wi-Fi performance and robustness required for reliable video delivery inside the home.”

The Cannes Wi-Fi's compatibility with ST's Cannes SoC family enables OEMs to leverage the existing large ecosystem to easily design innovative client boxes on multiple middleware products.
