This increase in OFDM support allows for downstream capacities ranging from 5 Gbit/s to 8 Gbit/s , placing it well ahead of standard DOCSIS 3.1 hardware.
The BCM3392 serves as the direct successor to the widely deployed BCM3390 . Its primary enhancement is its ability to handle significantly more data through advanced channel bonding:
This means any cable provider or hardware manufacturer worldwide can source this chip to build high-speed modems. This provides a vital "stretch" or "bridge" technology, allowing operators to stay competitive against fiber-to-the-home (FTTH) services while they plan their long-term transition to newer standards.

The BCM3392 was sampled in 2023, passed DOCSIS certification in 2024, and is currently in full production. BCM3390 - Broadcom Inc.
One of the most significant aspects of the BCM3392 is its commercial availability. Unlike Broadcom’s DOCSIS 4.0 chipsets, which are currently restricted by Joint Development Agreements (JDAs) to a select few major operators (such as Comcast and Charter), the BCM3392 is . This increase in OFDM support allows for downstream
Announced a full portfolio of data modems and gateways powered by the BCM3392.
Developed the CVA438z (a cable modem/VoIP adapter) and the CGA438A (a DOCSIS 3.1 gateway) using the chipset. This provides a vital "stretch" or "bridge" technology,
Several leading Customer Premises Equipment (CPE) manufacturers have already integrated the BCM3392 into their product lines:
