S910 | 3U CompactPCI MIL-STD-1553B Board

Aitech’s S910 MIL-STD-1553B board – with its companion S911 mezzanine – features four BU61688P3 Mini-Advanced Communication Engine or 4 BU63825G3 SP’ACE hybrid by DDC in a single 3U cPCI slot. Each 1553 channel/terminal provides dual transceiver and encoder/decoder, complete MIL-STD-1553B protocol, minimum of 16k 16-bit words of shared RAM, and memory management logic for all three modes (BC/RT/MT).

Background Mode Operation prevents inadvertent access to the card during power-on selftest. On-board Interrupt Mask and Interrupt Status Registers support flexible operation for both interrupt and polling applications.
