Description
DE8123 | PCB Type Bus Coupler, 3 Stub LTRM, MIL-STD-1553
The DEICO MIL-STD-1553 PCB Type Bus Coupler series offers a reliable and economical solution for building communication bus systems in demanding applications. Typical applications for the DEICO MIL-STD-1553 bus couplers include military and civilian bus systems, as well as test and development environments. The DE8123 model is a 3-stud bus coupler with left-side termination. Compared to the DE8113, the termination is integrated on the opposite side, allowing for different system topologies. Compared to the unterminated DE8103, this model offers an integrated termination function, while compared to the DE8133 it only has single-ended termination. Product features of the series: Transformer ratio: 1:1.41 Stub resistance: 59 ohms ±1% (1W) Characteristic impedance: 78 ohms Common mode rejection: -45 dB max @ 1 MHz Droop: max. 20% at 250 kHz Overshoot & Ringing: ±1.0 V peak
Stub voltage: 1.0 V to 14.0 V p-p
Bus input impedance: min. 3000 ohms
