## 56G Connector Focuses on High-Speed Modular Systems

TE Connectivity has introduced its 56G MezzaWave connectors and cable assemblies, designed to support high-speed data transfer in edge AI, data centers, industrial automation, robotics, and aerospace systems. These connectivity solutions offer support for next-generation modular architectures requiring high bandwidth and reliable signal performance.

### High-Speed Performance
The MezzaWave connector family is based on an open-pin platform that supports data rates up to 56 Gbps using PAM4 modulation. This technology provides higher data transfer rates in constrained system designs and meets the increasing bandwidth needs in edge AI processing and distributed computing environments.

Signal integrity has been treated as a primary priority due to the potential for interference and attenuation to affect performance in high-density systems. The connector structure offers optimized routing and grounding, supporting stable transmission at high data rates.

### Design Flexibility
The connectors are offered with a 1.27 mm pitch and a variable pin count ranging from 80 to 560 pins. This allows them to meet a wide range of board-to-board connectivity needs. The stack height, ranging from 7 mm to 10 mm, provides extra flexibility for system designers managing space in confined areas.

Integrated power pins support up to 1.6 A, reducing the need for additional components, thereby simplifying board layouts and improving power distribution.

### Compatibility with Existing Systems
The MezzaWave series is suitable for direct replacement without modifying existing printed circuit board (PCB) designs. This feature reduces engineering effort while accelerating system upgrade processes.

The connectors comply with VITA 57.1 (FMC) and VITA 57.4 (FMC+) standards, as well as ANSI requirements, ensuring interoperability with common modular platforms in embedded computing and aerospace applications.

### Mechanical Durability and Environmental Performance
The combination of BGA (Ball Grid Array) technology and robust mechanical structure ensures reliable electrical connections. These connectors are designed to withstand up to 1000 mating cycles, which translates to high durability during maintenance and installation.

The operating temperature ranges from -55°C to 125°C, making them suitable for harsh environments such as aerospace and defense. They offer reliable performance under conditions like thermal extremes and vibration.

### Cost and System Efficiency
The ability to directly replace existing components and the reduction in the number of separate elements required can lower system costs. The use of BGA technology increases manufacturing efficiency, providing a cost advantage of 20% to 30% depending on the system configuration.

### Importance in Digital Supply Chain and Edge AI Infrastructure
With the growth of data-intensive applications, connectivity technologies enable the development of modular and scalable architectures. The MezzaWave platform supports the development of high-performance systems for real-time data processing and system integration.

The introduction of 56G-enabled connectors demonstrates advancements in connectivity design in response to the increasing demands for higher bandwidth, lower latency, and increased system flexibility in industrial and computing environments.
