Broadcom: 3392 [best]

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 .

Sampling began in 2023, with DOCSIS certification achieved in 2024. It is currently in full production. Primary Manufacturers: Vantiva (formerly Technicolor): Launched the , a high-end gateway featuring , 2.5 GbE ports, and 2GB of RAM. Compal Broadband Networks (CBN): broadcom 3392

: It serves as an incremental upgrade for operators who want to offer higher speeds now while they evaluate the timing and costs of a full DOCSIS 4.0 transition. It is currently in full production

While the BCM3392 is primarily a downstream-enhancing chip, the DOCSIS 3.1+ ecosystem also promises meaningful upstream improvements. Although the BCM3392 can support theoretical upstream speeds of about 1.7 Gbps under optimal conditions, initial real-world estimations for the DOCSIS 3.1+ approach put downstream speeds around 8 Gbit/s and upstream speeds above 1 Gbit/s.

The is a next-generation System-on-a-Chip (SoC) designed to supercharge broadband delivery over hybrid fiber-coaxial (HFC) networks . As cable operators balance the massive infrastructure costs of moving to DOCSIS 4.0 against growing subscriber demands, this specific silicon chip offers a critical stepping stone. Frequently referred to as the driving force behind DOCSIS 3.1+ (or DOCSIS 3.1 Extended), the Broadcom 3392 enables multi-gigabit internet speeds without forcing providers to immediately rebuild their physical network architectures. What is the Broadcom BCM3392?

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.
