Realtek Broadband Access Controller Product Details

The broadband access controller product line is known for its high performance and integration. These controller chips are widely used in xDSL modems, optical network terminals (ONTs), cable modems, and a variety of hybrid access devices to provide stable and reliable broadband access services for home and business users.

The xDSL access controllers support ADSL2+/VDSL2 and other mainstream standards, and integrate high-performance DSP cores and rich interface functions. Using advanced process technology, these chips provide Gigabit-class access capability while achieving industry-leading low power performance, making them particularly suitable for carrier-grade equipment that requires 24-hour operation. Some high-end models also support vectoring technology, which effectively suppresses line crosstalk and maintains stable performance in long-distance copper transmission scenarios.

In the field of fibre access, GPON/EPON ONU controllers integrate MAC, SerDes and TC layer functions, support 2.5G downlink and 1.25G uplink rates, and are compatible with ITU-T G.984 and IEEE 802.3ah standards. With a built-in high-performance CPU and hardware acceleration engine, these chips can easily handle complex protocol stacks and data stream classification, while providing a rich set of user-side interfaces, including Gigabit Ethernet, USB3.0, and PCIe, to meet the development needs of multi-functional ONT devices.

Key technical features of the Realtek Broadband Access Controller include:

Multimode support: Single chip supports multiple access technologies (xDSL/PON/Cable), reducing development complexity for equipment vendors

Hardware acceleration: Built-in encryption engine, traffic manager and QoS processor to reduce the CPU burden

Green and energy-saving: Dynamic power management technology, automatically adjusting the working state according to the traffic load.

High Integration: Reduce the number of peripheral components, reduce BOM cost and PCB area.

Software compatibility: Provide a unified software development kit for product series upgrading

The Realtek RTL960x series is the current mainstream PON ONU single-chip solution. This series of chips integrates the ARM Cortex-M4 core, supports VoIP, TR-069 remote management, and advanced QoS features, and is widely used in Fibre-to-the-Home (FTTH) terminal equipment.

Realtek Gateway Controller Solutions

In the smart gateway and router market, Realtek's controller solutions have won wide adoption for their cost-effectiveness and rich feature set. These gateway controllers integrate high-performance CPUs, hardware acceleration engines, and a rich set of network interfaces to handle increasingly complex routing, firewall, and QoS functions, while maintaining low power consumption and cost.

The Realtek RTL819x family of single-chip solutions integrates a multi-core CPU, Wi-Fi baseband, and RF front-end with support for dual-band concurrency and MU-MIMO technology to deliver stable Gigabit wireless connectivity. With a built-in hardware NAT acceleration engine, these chips can easily handle IP forwarding traffic above 2000Mbps, meeting the needs of high-bandwidth applications such as 4K video streaming and online gaming. They also support advanced features such as parental control, guest network and intelligent QoS, providing a complete network hub solution for the modern smart home.

Key technical advantages of Realtek gateway controllers include:

High level of integration: Single-chip integration of CPU, switch, and wireless functions, reducing BOM costs

Scalable performance: Multi-layered product line from single-core 600MHz to quad-core 1.4GHz

Rich interfaces: supports Gigabit Ethernet, USB 3.0, SATA III and other expansion interfaces

Security features: Built-in firewall, DPI and anti-DDoS attack protection.

Software ecosystem: OpenWRT and other open source systems support
