Realtek Semiconductor will participate in the International Consumer Electronics Show (CES) held in Las Vegas, USA, from January 7 to January 10, 2025. This year's exhibition centers on the theme "Realtek AI: Changing the Future", highlighting AI-driven innovative solutions. At the Palazzo Tower, Realtek will showcase a variety of Bluetooth solutions, with applications ranging from personal devices to automotive use, demonstrating their versatility and broad applicability.

Bluetooth Helmet Solution: RTL8763EFL

With the rise in commuting and outdoor activities, users of traditional Bluetooth helmets face numerous challenges, such as poor audio quality that makes GPS navigation, music, or calls hard to hear; ineffective noise management; unstable Bluetooth connections leading to frequent disconnections and pairing difficulties; and insufficient battery life. Addressing these pain points, Realtek's innovative Bluetooth technology redefines the functionality and user experience of Bluetooth helmets.

Realtek's Bluetooth helmet solution leverages multiple cutting-edge technologies to enhance the user experience comprehensively. Its exceptional audio quality, powered by high-gain technology and 48kHz/16-bit playback with dynamic range control, ensures clear and realistic sound even in noisy environments. For calls, it employs 16kHz/16-bit high-quality audio and AI noise suppression technology to effectively block wind and road noise, delivering crystal-clear conversations even at speeds of up to 100 km/h. Additionally, support for Bluetooth 6.0 provides stable and reliable connectivity. Realtek's one-to-one front-and-rear intercom function resolves the issue of traditional helmets' inability to enable real-time communication between front and rear seats. With a single-button operation, users can achieve seamless and efficient communication, whether riding or engaging in team interactions.

Optimal Over-the-Counter Hearing Aid Solutions: RTL8773D/RTL8773DO

Realtek offers innovative solutions to address the key challenges of hearing aids. For the issue of excessive noise in traditional hearing aids, Realtek employs AI noise reduction technology. Using deep neural network (DNN) training, it enhances the signal-to-noise ratio (SNR) by 10 dB, significantly reducing background noise and improving listening comfort.

To tackle the poor sound quality caused by the comb filter effect, Realtek achieves ultra-low latency audio processing of just 0.5 milliseconds, far surpassing other products on the market, thereby delivering a substantial improvement in sound quality.

Additionally, Realtek has developed an integrated charging case that combines hearing aid charging, a remote control, an microphone, and TV streaming functionality. This addresses the inconvenience of scattered traditional hearing aid accessories, providing an outstanding user experience.

The RTL8773DO further distinguishes itself as the first Bluetooth SoC solution to support Apple hearing aid functionality.

AI Noise Reduction and Auracast Bluetooth SoC Solution: RTL8773D

The RTL8773D is a high-performance Bluetooth SoC solution specifically designed for audio devices, integrating AI technology with advanced audio capabilities to deliver an exceptional listening experience. Its core features include AI noise redution, AI environment classification, and AI-assisted beamforming, enabling intelligent sound processing tailored to different scenarios for clearer speech and audio quality.

The solution leverages Bluetooth 5.3 technology (legacy + LE Audio + BLE) and features a Cortex-M4 processor optimized for neural network applications, offering a computational capability of 2.56 GOPS and equipped with 4.3MB of RAM.

Additionally, its low-power hybrid adaptive ANC (Active Noise Cancellation) technology and Class AB+D audio amplifier strike an optimal balance between high performance and energy efficiency.

Highly Integrated BT/Wi-Fi Twin-Chip Smartwatch Solution: RTL8773EWE+RTL8720C

The RTL8773EWE-VP integrates a CPU, PSRAM, audio codec, 2.5D image engine, display controller, peripherals, and BT/BLE wireless functionality into a single chip, delivering robust performance and high integration. Meanwhile, the RTL8720CF, a low-power Wi-Fi chip, features ultra-low power consumption and a compact package design, making it ideal for space-constrained applications. These two chips can share a crystal oscillator and antenna, significantly improving cost efficiency and reducing PCBA space requirements. Additionally, the dual-chip solution supports a mailbox mechanism and PTA (Packet Traffic Arbitration) technology, optimizing BT and Wi-Fi coexistence performance.

With the integrated HDK/SDK solution, users can easily implement coordinated BT and Wi-Fi applications, making it an ideal choice for multifunctional smart devices.

Comprehensive BLE Audio Sharing and HID Dongle Solution: RTL8763EAU (Dongle), RTL8762G (HID), RTL8763E/RTL8773D (LE Audio Headphones)

Realtek offers an all-encompassing HID + LE Audio sharing solution to meet diverse application needs. The RTL8763EAU HID Dongle supports HID functionality and Auracast transmission, ensuring stable connections for wireless devices. The RTL8762G features three modes: BLE, 2.4GHz, and USB HS, delivering a USB and wireless report rate of up to 8K for real-time responsiveness.

The Auracast Audio Sharing SDK simplifies setup and enhances user experience. For LE Audio headphones, the RTL8763E and RTL8773D provide efficient solutions tailored for PC peripherals, TVs, and docking products. This comprehensive solution, backed by Realtek's One-Stop technical support, seamlessly integrates HID and Auracast, offering robust and reliable technology for next-generation audio and peripheral applications.

At the 2025 CES, Realtek showcased its technological expertise and strong R&D capabilities, continuing to drive advancements in AI and wireless technologies. Looking ahead, Realtek remains committed to delivering more innovative and intelligent solutions, providing global customers with increasingly convenient and high-quality product experiences.
