Fix — Broadcom 3392
: It passed DOCSIS certification in 2024 and is officially in production as of early 2025.
Early adopters are already integrating this silicon into consumer hardware. For example: Vantiva CGA 438A : One of the first gateways powered by the BCM3392. Compal Broadband Networks (CBN)
The DOCSIS 3.1+ path, championed by the BCM3392, offers a dramatically different economics:
To put it simply:
The BCM3392 is a DOCSIS 3.1+ cable modem SoC that pushes the limits of existing hybrid fiber-coaxial (HFC) networks. Built as a bridge between the current widely deployed DOCSIS 3.1 standard and the next-generation DOCSIS 4.0, this chip allows cable operators to provide using their current network equipment.
The chip is built to handle heavy traffic in both directions. It supports along with eight single-carrier QAM upstream channels. This ensures that as user activity moves toward content creation and video conferencing, the network can handle the upstream demands efficiently. 3. Integrated RDK-B Software Support

Another key product is the cable modem. This device is equipped with the BCM3392 chipset, supports Wi-Fi 7 (802.11be) with dual-band capabilities, and incorporates a 2.5 Gbps LAN port. These CBN and Vantiva solutions demonstrate that the BCM3392 is not just a theoretical chip, but the core of real-world devices that network operators can deploy today.
This article provides an in-depth look at the Broadcom BCM3392, its technical advancements, applications, and its role in the future of broadband. What is the Broadcom BCM3392?
Though the BCM3392 does not appear on Broadcom's public-facing product page, the chip is already being integrated into commercial hardware by top-tier Original Design Manufacturers (ODMs): : It passed DOCSIS certification in 2024 and
: The chip sampled in 2023, passed DOCSIS certification in 2024, and is currently in full production. 5. Conclusion
: Broadcom began sampling the chip in 2023, and it passed official DOCSIS certification in 2024.
Several major manufacturers are integrating the BCM3392 into their latest Customer Premises Equipment (CPE): Compal Broadband Networks (CBN) The DOCSIS 3
