DOCSIS 4.0
The Broadcom BCM3392 is a high-performance cable modem chip . It is designed to deliver multi-gigabit internet speeds over existing coaxial cable networks. 🚀 Key Features and Capabilities Next-Gen Speeds : Supports download speeds up to 10 Gbps . Supports upload speeds up to 6 Gbps . DOCSIS 4.0 Standard : Utilizes Full Duplex DOCSIS (FDX) technology.
- It is a CPU + Switch + Security Engine. Unlike a standard Wi-Fi card, the BCM3392 integrates a high-performance ARM Cortex-A9 processor with a packet processing accelerator.
- Target Market: It was specifically designed for DOCSIS 3.0 and 3.1 cable gateways (routers provided by ISPs like Comcast, Spectrum, and Virgin Media) as well as high-end retail routers.
- Vendor-specific firmware and proprietary driver components can limit open-source support and customizability.
- Wireless functionality typically depends on separate radio modules—Wi‑Fi performance is not intrinsic to the SoC alone.
- Exact feature set and performance vary by BCM3392 SKU and vendor board design.
