Extending MIL-STD-1553 bandwidth: A study of impairments, EMI, and channel capacity

VMEbus Systems / August 2005 MIL-STD-1553 is a serial, time-division multiplex data bus that has been used as the primary command and control data interconnect in military aircraft for the past three decades. MIL-STD1553’s robust performance, high level of interoperability, large installed base, and well established infrastructure of vendors has made it the network of choice for military avionics systems. While MIL-STD-1553’s 1 Mbps data rate is adequate for current avionics applications, there are emerging applications that require higher bandwidth. The challenge facing the military avionics industry is finding cost effective methods of supplementing MIL-STD-1553 with higher bandwidth data communication channels.
