TTEEnd System A664 Lab

Deterministic Ethernet End System for Development Efforts of Aircraft, Rotorcraft & Launch Vehicle Electronics

The TTEEnd System A664 Lab for development and laboratory environments is a high-performance PMC/XMC card with three 10/100/1000 Mbit/s Ethernet ports running at full-duplex speeds. The end system uniquely supports three standard traffic classes: standard Ethernet (IEEE 802.3) as well as rate-constrained (ARINC 664 p7) and time-triggered (SAE AS6802) traffic in parallel on one physical infrastructure. Therefore the board is 100 % compatible to all standard (IEEE 802.3) Ethernet off-the-shelf components as well as ARINC 664 p7 system architectures. Furthermore the board allows for flexible and easy physical layer configuration as it supports copper and optical SPFs to be installed.

The TTEEnd System A664 Lab provides a fully in hardware implemented and therefore deterministic IP/UDP communication layer for critical traffic which offloads the host CPU. It enables real-time Ethernet communication between an embedded computer and TTEthernet switches for redundant channels in a safety-critical system.

Further unique features include a fixed latency and transmission jitter in the sub-microsecond range and unmatched bandwidth efficiency while maintaining full determinism (up to 95 % utilization of available network bandwidth).

The TTEEnd System A664 Lab is available as PMC, PCI, XMC and PCIe variant. The card could also be used on CPCIe, VME, VPX and VXS carrier boards (additional testing required) and can therefore be plugged into various PCs or embedded CPU boards for lab use or field applications. 

Key Benefits
