Microchip and Marelli demo ASA Motion Link connectivity for automotive displays
Microchip Technology and Marelli have demonstrated a display connectivity solution using the open ASA Motion Link standard to transmit video from centralized vehicle computers to automotive displays. The architecture supports data rates up to 16 Gbps and aims to provide a standardized, interoperable alternative to proprietary SerDes technologies for software-defined vehicles.
Key Takeaways
- Architecture supports high-speed data rates up to 16 Gbps for navigation, infotainment, and vehicle control interfaces
- VS7000 ASA-ML chipset enables centralized graphics processing rather than distributing compute across individual displays
- Security features include link-layer authentication, encryption, and high immunity to electromagnetic interference
- System utilizes Time Division Duplex and Forward Error Correction to lower power consumption in automotive environments
Why It Matters
This demonstration signals a shift away from fragmented, proprietary video connectivity toward interoperable standards in the automotive display market. By decoupling hardware from software through an open SerDes standard, manufacturers gain greater sourcing flexibility and can consolidate heavy graphics processing into a single central computer. This transition is critical for the streaming ecosystem as vehicles evolve into high-bandwidth consumption hubs requiring secure, low-latency video delivery. As software-defined vehicles become the industry benchmark, the adoption of standardized links will likely reduce integration costs for infotainment providers. Watch for whether other Automotive SerDes Alliance members release compatible hardware to validate this interoperability framework.
