Robust Deterministic Ethernet end system for aircraft, rotorcraft & land vehicle electronics
The TTEEnd System A664 Rugged is equipped with three 10/100/1,000 Mbit/s Ethernet P14 rear-I/O ports running at full-duplex speeds. The conduction-cooled design of the board enables operations under the harshest conditions: withstanding forces up to 40G, vibrations of 2,000 Hz and temperatures of up to +85 °C while remaining fully operational at an altitude of 18,300 m (60,000 ft).
The rugged 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 with all standard (IEEE 802.3) Ethernet off-the-shelf components as well as ARINC 664 part 7 system architectures.
The TTEEnd System A664 Rugged 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 Rugged is available as PMC and XMC with P14 rear-I/O variants.
