Leading tier-one original design manufacturers (ODMs) have heavily adopted the chipset to anchor their hardware portfolios. Notably, network equipment giant Compal Broadband Networks (CBN) launched an entire fleet of 10G downstream data modems and residential wireless gateways powered entirely by the BCM3392 SoC. Moving forward, consumers will see this silicon embedded in premium, operator-issued gateways and high-end retail cable modems. Share public link
Supports two 96 MHz OFDM-A channels and 8 single-carrier QAM upstream channels.
The BCM3392 occupies a specific niche in the "10G" ecosystem: broadcom 3392
Supported two 192 MHz-wide OFDM downstream channels. This architecture typically capped realistic consumer downstream speeds to roughly 1 Gbps to 2 Gbps under standard operating conditions.
: Operates on existing DOCSIS 3.1 networks using older CMTS (Cable Modem Termination System) chassis equipped with updated software. 3. Strategic Advantages for Operators Share public link Supports two 96 MHz OFDM-A
: It supports four 192MHz-wide Orthogonal Frequency Division Multiplexing (OFDM) downstream channels, doubling the capacity of the previous generation.
The BCM3392 is commonly used in:
The Broadcom BCM3392 is a high-performance cable modem and gateway chipset built to succeed the widely deployed Broadcom BCM3390 . While its predecessor laid the groundwork for modern gigabit residential internet, the 3392 expands on this architecture to extract maximum capacity out of existing cable spectrums.
maximizes DOCSIS 3.1+ efficiency with a lean, highly specialized four-OFDM architecture, MaxLinear's Puma 8 tackles the market from a multi-mode angle, capable of scaling up to five OFDM channels or serving as a baseline component for Extended Spectrum DOCSIS (ESD) 4.0 configurations. This direct competition keeps hardware pricing stable, allowing operators to deploy high-capacity modems with only marginal cost increases over legacy gear. Summary: Future-Proofing Existing Coax BCM3390 - Broadcom Inc. : Operates on existing DOCSIS 3
: The chip passed DOCSIS certification in 2024 and is currently in active production. Why the BCM3392 Matters
is a next-generation System-on-a-Chip (SoC) designed to significantly boost the performance of cable broadband networks without requiring a full transition to DOCSIS 4.0. By expanding the capabilities of existing DOCSIS 3.1 infrastructure, this chipset allows cable operators to offer "fiber-like" speeds over traditional coaxial cables. Key Technical Specifications represents a major leap over previous hardware like the Broadcom BCM3390 Quad OFDM Bonding
