The VA700R series supports 4Gbps connections up to 40 meters, providing power and control through the cable for enhanced vehicle sensor connectivity.


Valens Semiconductor has introduced the VA700R Series, which enhances bandwidth and link distance for vehicle sensor connectivity. The series supports connections of 4Gbps up to 40 meters (130 feet), providing power and two-way control through the cable. It aims to develop visibility tools for truck drivers.

The series includes the VA7021R Serializer and VA7004R Deserializer, which improve bandwidth and distance for surround-view and rear-view systems in medium—to large vehicles. The system supports cameras up to 8MP (4K) at 30 frames per second and is suitable for Advanced Driver Assistance Systems (ADAS). Demonstrations of the VA700R are available, and engineering samples will be released to customers by mid-2024.

Long vehicles face visibility challenges due to long-distance connectivity requirements in harsh Electromagnetic Compatibility (EMC) environments. The company claims to provide solutions that enhance ADAS systems in larger vehicles.

Some of the key features of the VA700R Series include:

  • AEC-Q100 Qualified: Automotive Grade 2; operates between -40°C to +105°C.
  • Low Power Consumption: The serializer is typically under 220 mW.
  • EMC Performance: Resists EMC, environmental interferences, and cable aging.
  • Real-Time Applications: Supports uncompressed, ~10μs latency for real-time processing.
  • Functional Safety: ASIL-B compliant (ISO 26262); aligns with MIPI CSE.
  • Low-Cost System Design: This design avoids protocol conversion costs, supports non-shielded cables/connectors, and includes internal PWM for synchronization.

“Valens Semiconductor’s connectivity solutions are high-performance – and that doesn’t just mean the highest bandwidth or the lower error rate – it also means the longest link distance,” said Gideon Kedem, SVP and Head of Automotive Business at Valens Semiconductor. “Our chipsets are the connectivity infrastructure upon which automotive OEMs and Tier 1s can build future innovations. With the unprecedented resilience and link distance of the VA700R, these innovations will become available to millions of truck drivers worldwide, who operate the most dangerous vehicles on the road while having to contend with limited visibility.”
