Features and Benefits

Automotive manufacturers face increasing bandwidth demands driven by data-rich applications such as advanced driver-assistance systems (ADAS), radar, LiDAR, zonal architecture and central compute modules. Older, lower-speed twisted-pair solutions lack the performance to meet the needs of these next-generation applications.

High-speed twisted-pair connectors and cable assemblies are necessary to support advanced automotive Ethernet applications. These connector systems must be compact enough to fit within the space constraints of today’s modules while ensuring EMI resistance and signal integrity that support high-speed data rates.

The HSAutolink G Multi-Gigabit Differential Connector System delivers high data rates in a footprint small enough to fit within the footprint of existing USCAR systems. Superior EMI shielding and controlled differential impedance deliver exceptional signal integrity, enabling data rates up to 25Gbps. These connectors support a variety of next-generation Ethernet applications and permit scalable, easily upgradable architectures. The USCAR-compliant cavity and interface design simplifies system integration and validation, reducing costs and accelerating time to market.

Compact, USCAR-Compatible Design for Centralized Compute Systems

The HSAutoLink G system supports zonal and centralized compute architectures, enhancing scalability and future-proofing designs by allowing high-speed, Ethernet-based data aggregation and processing. The interface fits within the same footprint as incumbent systems, simplifying redesign work.

Enables scalable, high-bandwidth data transmission
Multi-gig performance up to 25Gbps supports next-generation applications such as ADAS, LiDAR and central compute modules, avoiding bandwidth bottlenecks and reducing upgrade and redesign costs.

Provides reliable signal integrity
Controlled 100-Ohm impedance and enhanced EMI shielding support exceptional performance in dense environments, which helps prevent signal failures, validation delays and costly design changes.

Supports second-source flexibility
The USCAR 777-U-xxx-x-Z01 interface and cavity compatibility allow drop-in replacement of industry-standard twisted-pair data connectors, minimizing redesign costs and providing a second-source solution that reduces supply chain risks.

Minimizes assembly errors
The anti-stubbing terminal design improves reliability and reduces the risk of validation failures.

Ensures reliable connectivity in harsh environments
A robust contact interface with precision crimping and available connector position assurance and terminal position assurance reduces the risk of mis-mating or inadvertent disconnections in high-vibration conditions.
