The is a high-performance DOCSIS 3.1 cable modem chipsets designed for the next generation of high-speed broadband internet. As a successor to earlier DOCSIS 3.0 and initial 3.1 silicon, the BCM3392 enables cable modems and gateways to deliver multi-gigabit speeds to residential and business customers, utilizing existing hybrid fiber-coaxial (HFC) infrastructure.
For cable operators (such as Comcast, Charter, and Virgin Media), the BCM3392 offered a strategic advantage. It allowed them to offer competitive “multi-gig” services over existing coaxial wiring—the same infrastructure already connected to over 90% of American homes—without the astronomical expense of running new fiber to each residence. The chip’s power efficiency and high integration level also reduced the bill of materials (BOM) for retail cable modems and gateways, fostering a healthy competitive market for consumer premises equipment (CPE). broadcom 3392
: As of early 2025, the BCM3392 has passed DOCSIS certification and is in active production. Device Adoption : Hardware manufacturers like Compal Broadband Networks (CBN) The is a high-performance DOCSIS 3
While the industry is gradually shifting toward DOCSIS 4.0, the BCM3392 serves as a critical "bridge" technology. It allows internet service providers (ISPs) to offer fiber-like speeds—reaching up to —without the massive capital expenditure required for a full network overhaul to DOCSIS 4.0.
