: The chip was sampled in 2023, passed official DOCSIS certification in 2024, and is currently in mass production as of early 2025.
The is the powerhouse behind the next wave of cable internet, often referred to as DOCSIS 3.1+ . It's designed to squeeze even more performance out of existing cable lines before the full industry shift to DOCSIS 4.0. broadcom 3392
As cable operators migrate from DOCSIS 3.0 to DOCSIS 3.1 and beyond, the demand for SoCs capable of handling higher channel bonding, lower latency, and increased upstream capacity has grown. The Broadcom BCM3392 addresses these requirements by integrating a DOCSIS 3.1 PHY, a high-performance CPU subsystem, packet processing engines, and multiple networking interfaces onto a single die. It is commonly found in premium cable modems, residential gateways, and integrated access devices (IADs). : The chip was sampled in 2023, passed
For standard households (300–600 Mbps plans), yes. For Gigabit power users, no. As cable operators migrate from DOCSIS 3
In this comprehensive guide, we will explore the architecture, use cases, performance metrics, and the legacy of the Broadcom 3392.
