Valens, a developer of high-speed in-vehicle connectivity systems, has launched a new range of chipsets that enable speeds of up to 8 Gbps.
The company says the VA7000 family of automotive chipsets will deliver “ultra-high-speed connectivity” with the most resilient physical layer (PHY) for error-free links and high EMI immunity.
Valens adds that the VA7000 chipsets will be “the first in the industry” to implement the MIPI A-PHY SM standard for advanced driver-assistance systems (ADAS) and autonomous driving systems (ADS).
MIPI A-PHY, now in its final approval phase, specifies in-vehicle high-speed data transmission over lightweight wiring harnesses for up to 15 meters, with adaptive noise cancellation and retransmission mechanisms to guarantee superior EMC/EMI performance.
The MIPI Alliance is a leading standards development organization for interface specifications. Its ubiquitous CSI-2 and MIPI DSI-2SM camera and display interfaces are widely implemented for sensor connectivity.
The VA7000 family has been designed to support the current and future gears of MIPI A-PHY – from 2 Gbps to 16 Gbps as defined in version 1.0, and with a roadmap to 48 Gbps and beyond as expected in future versions.
The first chipsets in the family include:
- the VA7031 Serializer designed to support remote long-reach connectivity of CSI-2-based image sensors, radars, LiDARs, with link speeds of up to 8 Gbps;
- the VA7042 Deserializer, featuring two independent receiver links, with speeds of up to 8 Gbps each, with an additional local CSI-2 local input port to support more complex topologies when necessary; and
- the VA7044 Deserializer, featuring four independent receiver links, with speeds of up to 8 Gbps each, with an additional local CSI-2 local input port.
The VA7000 family is a hardware-based solution optimized for asymmetric links with no software stack. It guarantees a high-performing, simplified architecture, leading to a reduction in wire harness complexity and lower total system costs.
It also enables the convergence of additional protocols (I2C, GPIOs, clock and frame sync), while guaranteeing near-zero latency to support time-sensitive, high-throughput traffic for advanced computer processing.
Daniel Adler, vice president, automotive business unit at Valens, says: “The VA7000 family is the first to implement the MIPI A-PHY specification, confirming Valens’ commitment to driving industry standards with innovative connectivity solutions.
“MIPI A-PHY delivers an interoperable ecosystem, bringing considerable benefits to both OEMs and Tier-1s, such as reducing complexity and lowering total system costs, without compromising performance.”
Ian Riches, vice president for the global automotive practice, strategy analytics, says: “The development of a standard-compliant chipset to support the need for resilient, higher bandwidth in-vehicle connectivity is a major advancement in the automotive field.
“Valens’ ability to deliver such speeds over long-reach wiring harness can considerably simplify in-vehicle architecture, while ensuring superior performance and safety.”
