This achievement signifies that the domestically produced automotive high-speed video transmission chip has met stringent automotive-grade reliability standards, laying a solid quality foundation for localized applications in large-screen display scenarios for vehicles.
RuiFake Semiconductor's automotive SerDes chip has obtained AEC-Q100 certification
Core Hardware Capabilities: High-Speed Transmission + Full-Scope Compatibility, Empowering the In-Vehicle Large Screen Ecosystem
On March 30,2026, the AEC-Q100 certification certificate awarding ceremony was successfully held. Key attendees from both parties, including Wang Lixin, Co-founder and Vice President of RuiFak Semiconductor, and Li Yabin, Deputy General Manager of GRGTEST Tianjin Company, jointly witnessed this significant milestone in the automotive-grade certification of domestically produced automotive chips.
The NS6238 is a HSMT-standard automotive high-speed video transmission serial chip independently developed by Rui Fa Ke, featuring outstanding core performance:
Supports DP/eDP 5.4Gbps HD video input
Supports ultra-high-speed serial output up to 12.8 Gbps
Supports MST and superframe core technologies
Compatible with de-serializer chips such as NS6139/NS6429/NS6129 for seamless pairing
The chip comprehensively supports premium cabin scenarios including the central control screen, passenger entertainment display, and rear-seat large screens, precisely meeting the high-speed transmission requirements for high-definition display in automotive cabins.
