Product Characteristics
Native SparkLink SLE
Native Standard Compatibility for Industrial Real-Time Control, VR/AR Wireless Streaming, and Low-Latency Gaming & Audio-Visual Applications. The chip integrates two complete functional modules at the hardware level: ranging and sensing, and lossless real-time audio.
SLE+BLE Dual-Mode SparkLink
Dual-mode SparkLink integrates both SparkLink SLE and Bluetooth BLE RF/baseband units into a single chip. With independent protocol stacks and non-interfering resource allocation, it supports standalone SparkLink or Bluetooth operation, as well as simultaneous dual-protocol connectivity. This enables seamless compatibility with next-generation SparkLink devices and existing Bluetooth ecosystems.
Wi-Fi+SLE integration solution
The Wi-Fi + SLE solution adopts a tri-mode architecture that integrates Wi-Fi high-speed connectivity, Bluetooth LE, and SparkLink SLE low-latency communication into a single chip. Combining high-speed transmission, real-time control, and cloud connectivity, it addresses the limitations of traditional Wi-Fi in latency-sensitive applications and SLE in Internet connectivity. The solution is widely applicable to streaming devices and smart home hubs, including TVs, IPC cameras, smart gateways, and dash cameras.
SL Audio with LC3plus Audio Codec Standard Support
SL Audio is a new-generation self-developed low-latency underlying audio architecture specification of the SparkLink system, core-matched with the LC3plus enhanced audio codec. Under the same sound quality output conditions, it can further reduce transmission bandwidth and device power consumption by 30% compared with Bluetooth LC3 coding. Its native multi-audio-stream synchronization capability supports a single sound source device to distribute independent synchronous audio streams to dozens of receiving terminals, laying a core technical foundation for applications such as SL Cast broadcast audio, multi-channel audio-video synchronization and low-latency gaming headsets at the underlying protocol architecture level.
SL Cast
SL Cast is an exclusive new audio broadcast technology developed by the SparkLink Industry Alliance (SIA) based on the SL Audio low-latency audio architecture. It can be simply understood as a large-scale synchronous public broadcast system adapted to SparkLink links, with ultra-large-scale "one-to-many" synchronous audio distribution capability. The entire technology runs completely based on native SLE wireless links without relying on Bluetooth baseband cooperation.
SL Ranging
SL Ranging is a core key module of SparkLink technology in the high-precision spatial perception track. Relying on the carrier phase measurement scheme, it can be matched with the dual calculation logic of signal Round-Trip Flight Time (ToF) as needed to accurately calculate the spatial distance between two interconnected devices. Traditional Bluetooth relies on RSSI signal strength for distance measurement with poor accuracy, which cannot meet most high-precision service requirements. In contrast, SL Ranging can stably output centimeter-level high-precision positioning results in various complex environments.
