: Manufacturers like Compal Broadband Networks (CBN) and Vantiva have already announced or deployed 10G-capable gateways powered by the BCM3392.

The prominent broadband hardware supplier (formerly known as Technicolor) was among the first to market with BCM3392-powered gear. Their lineup features the CVA438z , a data-and-voice eMTA gateway, alongside the flagship CGA438A . These units target operators aiming for a rapid 8 Gbps downstream billing option. broadcom 3392

The BCM3392 sits in the mid-to-high range of Broadcom’s modem portfolio. It represents the bridge between standard gigabit internet and the emerging .

A critical feature for real-time applications like VoIP and gaming, the BCM3392 supports Active Queue Management (AQM) features often required by modern cable operators to reduce "bufferbloat" and ensure smooth packet delivery.

Latency under load (bufferbloat) is mitigated by DOCSIS 3.1’s active queue management (AQM) and Low Latency DOCSIS (LLD) support. Doubles this capacity by supporting four 192 MHz-wide

The Broadcom BCM3392 is a highly integrated system-on-a-chip (SoC) designed for the next generation of cable gateways, combining DOCSIS 3.1 physical layer (PHY) processing with a powerful application processor. This paper examines the architecture, key features, performance characteristics, and typical deployment scenarios of the BCM3392. Positioned as a solution for multi-gigabit home networking, the BCM3392 enables service providers to deliver data rates exceeding 1 Gbps downstream while supporting concurrent high-speed Wi-Fi and Ethernet backhaul.

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

One of the first public devices to feature the BCM3392 is the (formerly Technicolor). This cable modem gateway is a showcase for the chip's capabilities, as it pairs the new DOCSIS 3.1+ engine with the latest in wireless technology, Wi-Fi 7 (802.11be) . The CGA438A is designed to offer service providers a way to deliver multi-gigabit wireless connectivity without a bottleneck from the wired internet connection. Their lineup features the CVA438z , a data-and-voice

The Broadcom 3392 is designed for use in a variety of applications, including:

(Orthogonal Frequency Division Multiplexing) channels, doubling the 2-channel limit of previous generations [6, 7]. High Speeds : Capable of reaching downstream speeds of 7 to 8 Gbps Market Positioning : Often used in high-end home gateways, such as the Sagemcom F@ST 3897 Documentation & Resources
