    The new SAE Standard AS 6802, also called Deterministic Ethernet or TTEthernet®, is a natural extension of ARINC 664and standard IEEE 802.3 for hard, real-time applications. Deterministic Ethernet is scalable, open, real-time Ethernet. It constantly synchronizes the clocks in all devices to offer "zero jitter" precision timing in the sub-microsecond range. 

    Deterministic Ethernet supports mixed-criticality systems with three traffic classes:

    • Time-Triggered traffic (TT), AS6802 compliant
    • Shaped traffic, ARINC 664p7 compliant
    • Best Effort (BE) standard Ethernet traffic, IEEE 802.3 and IEEE 1588 compliant
    Our TTEthernet Development System is a complete solution for deterministic Ethernet, supporting both 10/100 Mbit/s ARINC 664 Ethernet interfaces and 1 Gbit/s Ethernet interfaces.
