Cons / Limitations

• Vendor-specific firmware and proprietary driver components can limit open-source support and customizability.
• Wireless functionality typically depends on separate radio modules—Wi‑Fi performance is not intrinsic to the SoC alone.
• Exact feature set and performance vary by BCM3392 SKU and vendor board design.

Memory and storage

• Supports DDR memory (DDR3/DDR3L in many designs) for firmware, routing tables, and packet buffers.
• Flash storage interfaces (SPI/NAND/EMMC) for firmware and configuration.

Typical target devices

• Cable and DSL modems with integrated routing
• Residential gateways supplied by ISPs
• Small business or SOHO routers
• Managed Wi‑Fi access points in consumer/ISP bundles

Key Specifications & Features

2.1 DOCSIS 3.1 Compliance

• Downstream: Supports up to 32×8 SC-QAM channels along with at least one contiguous OFDM block (typically 96 MHz), enabling raw downstream throughput of up to 1.6–2 Gbps depending on channel plan.
• Upstream: Supports up to 8×4 ATDMA and one OFDMA channel for improved upstream efficiency (up to ~200–300 Mbps).
• Backward compatibility: Full support for DOCSIS 3.0 and earlier networks.

Notable Devices Featuring the BCM3392:

• ARRIS / Surfboard SB6190: This is arguably the most famous device using the 3392. The SB6190 is a 32x8 DOCSIS 3.0 cable modem. Broadcom positioned the 3392 as the application processor managing the downstream/upstream channels.
• ASUS RT-AC86U: One of the most beloved "gaming routers" of its era. The AC86U leveraged the 3392’s dual-core power to run Trend Micro’s AiProtection and adaptive QoS without tanking performance.
• Netgear R7000P (Nighthawk): An update to the classic R7000, the "P" variant used the 3392 to manage MU-MIMO (Multi-User, Multiple Input, Multiple Output) traffic.
• Linksys EA8300 (Max-Stream): A tri-band router that relied on the 3392 to coordinate three separate radios simultaneously.

CPU and performance

• Multi-core ARM-based CPU subsystem (designed for networking workloads rather than general-purpose compute).
• Optimized for packet-processing throughput and control-plane tasks.
• Adequate for high-throughput home gateway features: NAT, DHCP, firewall, VPN termination (basic to moderate loads).

1. Introduction

As cable operators migrate from DOCSIS 3.0 to DOCSIS 3.1 and beyond, the demand for SoCs capable of handling higher channel bonding, lower latency, and increased upstream capacity has grown. The Broadcom BCM3392 addresses these requirements by integrating a DOCSIS 3.1 PHY, a high-performance CPU subsystem, packet processing engines, and multiple networking interfaces onto a single die. It is commonly found in premium cable modems, residential gateways, and integrated access devices (IADs).
