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.
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.
For the millions of homes and businesses relying on cable internet, the promise of gigabit speeds has long been a reality, but the industry is now setting its sights on the next frontier: 10-gigabit connectivity. The challenge, however, is monumental. Upgrading entire hybrid fiber/coax (HFC) networks to new standards like DOCSIS 4.0 is a capital-intensive, multi-year endeavor for providers like Comcast and Charter Communications. Enter the Broadcom BCM3392. This system-on-a-chip (SoC) represents a strategic evolution in broadband technology. Rather than mandating a complete network overhaul, the BCM3392 is designed to push the existing DOCSIS 3.1 standard to its absolute limit, achieving remarkable downstream speeds of up to 10 Gbps on the infrastructure already in place. broadcom 3392

The BCM3392 is not just a theoretical improvement; it is a vital part of the cable industry's strategy to compete with fiber providers.
The Broadcom 3392 runs . The chip is manufactured on a 40nm or 28nm process (depending on the revision), which is ancient by smartphone standards. In enclosed modem/router combos (gateways), the 3392 frequently hits 85°C–95°C. The is the powerhouse behind the next wave
Broadcom is notoriously closed-source with their wireless drivers, which makes open-source support difficult. However, the 3392 is old enough that the community has reverse-engineered or obtained binary blobs to make it work.
