TTEEnd System A664 Lab v2.0 is the new generation of high-performance deterministic Ethernet end system cards for laboratory evaluation, development and testing applications, based on our RTCA DO-254 DAL A certifiable TTEEnd System A664 Core IP Pro. It provides two 100/1,000 Mbit/s Ethernet ports running at full-duplex speeds and is available in two form factors XMC and PCIe. The end system uniquely supports three standard traffic classes: standard Ethernet (IEEE 802.3) as well as rate-constrained (ARINC 664 part 7) 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 part 7 system architectures.

The hardware architecture of TTEEnd System A664 Lab v2.0 maintains parity with the flight grade XMC card, which is MOSA / SOSATM / HOST aligned, providing a solution that eases the migration of lab-based applications into flight development programs.

The TTEEnd System A664 Lab v2.0 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 A664p7/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).
