5、 Analysis of Domestic Brand Competitiveness
|Brand | Technical Advantages | Market Positioning | Typical Application Scenarios|
|Lanqi Technology | DDR5 Standard Setter | Server/Data Center | Memory Modules, AI Accelerator Cards|
|Huineng Tai | PD protocol full certification coverage | Consumer fast charging accessories | Chargers, car chargers|
|Qinheng | RISVC+self-developed protocol stack | Internet of Things/Industrial Control | Keyboard HUB、 Smart devices|
|Jirui Zhiyuan | Ultra low power video conversion | Display devices/laptops | 4K/8K displays, VR devices|
|Aiwei Electronics | Industrial IC Expansion | Server/Automotive Electronics | Industrial Control Motherboard, In Vehicle System|
The current interface chip market presents a pattern of "foreign enterprises leading the high-end field, domestic substitution accelerating penetration":
International brands such as ADI and TI still have advantages in areas such as audio and high-speed Serdes;   
Domestic brands have achieved breakthroughs in segmented fields, such as Lanqi (memory interface), Huineng Tai (fast charging protocol), and Qinheng (RISCV full stack connection), which have entered the international supply chain and improved competitiveness through process innovation (such as 28nm low-power design) and protocol compatibility (such as PD3.1, HDMI 2.1).   
In the future, with the increasing demand for AI servers and in vehicle electronics, interface chips that support high reliability and multi protocol integration will become a key focus for domestic brands.
