Broadcom (News - Alert) Corporation, a specialist in semiconductor solutions for wired and wireless communications, launched a high-performance hybrid cable gateway set-top box solution that can enable home connectivity and content sharing.

John Gleiter, vice president of Set-top Box (News - Alert) Marketing for Broadband, said, “Broadcom's new BCM7145 is a giant step forward in set-top box gateway chip design and is a key enabler for an all-IP cable platform.”

“We have engineered a new solution that builds on Broadcom’s unmatched, broad-ranged expertise in set-top box devices and our breadth of broadband, MoCA 2.0, Gigabit routing and leading 5G 802.11ac wireless technologies. As a result, the BCM7145 is a breakthrough that delivers what operators want to compete in their markets,” Gleiter added.

Officials explained that the new platform serves as a set-top box offering that integrates DOCSIS 3.0 and Gigabit wireless gateway functionality with HEVC video decoders and quad video transcoders, offering them on a single piece of silicon.

The Broadcom BCM7145 delivers the combined functionality of five different devices. Hence, the platform becomes cost effective and consumes less power besides securely supporting multiple applications.

The device features dual-core CPU that can run multiple applications together in secure memory containers, thereby securing the system and leveraging CPU’s resources.

Broadcom’s new hybrid cable gateway SoC also features integrated full band capture tuner and spectrum analyzer technology. The former enables the 32 demodulators integrated inside the BCM7145 to be used for DVB-C/QAM and DOCSIS simultaneously. It provides channel flexibility up to 1GHz.

Full Band Capture enables optimized remote cable system troubleshooting with the help of a spectrum analyzer that reveals the cable system connection at the customer end reducing reduce customer service calls and cost.

Officials highlighted the fact that the new BCM7145 device features certifiable Euro/DOCSIS 3.0 modem stack, 5G 802.11ac wireless router, packet cable VoIP stack and Nexus-Trellis set-top box software. System integrators can develop complete solutions for global operators also, added officials.

Broadcom also announced a family of HomePlug AV2 devices that can achieve physical layer rates of up to 1.5 Gigabits per second (Gbps) over a home’s existing electrical wiring. These carrier-class devices deliver simultaneous multi-room HDTV distribution, low-latency real-time online 3D gaming and whole-home Internet coverage.
