4 Channels, MIL-STD-1553, Dual Redundant, Direct Coupled, Assisted Mode Capable (AMC)
MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus. It was originally designed for use with military avionics, but has also become commonly used in spacecraft On-Board-Data-Handling (OBDH) subsystems, both military and civil. It features a dual, redundant, balanced-line, physical layer; a (differential) network interface; time division multiplexing; half-duplex command/response protocol; and up to 31 remote terminals (devices).
FTF provides programmable 4 channels, dual-redundant, direct-coupled interfaces.
The FTA-FTF function modules are the improved assisted mode versions of the legacy FT1-FT6 functions and is the choice for all new programs. View our FTA-FTF MIL-STD-1553 Assisted Mode Product Improvement.
