The Iris-EXT-04-BRK is a breakout board for the Iris-030 Software Defined Radio (SDR) MIMO Bus. It connects to either the upstream or downstream MIMO bus connector on Iris-030 and provides access to power, general purpose input/output (GPIO), differential clocks, and high-speed serial links.
GPIO is presented through standard 2.54 mm GPIO headers, and the clock, as well as high-speed serial links, are presented through female MCX connectors. Power is shared between both upstream and downstream connectors, but no data lines are passed through. The Iris-EXT-04-BRK may also be conﬁgured to loop-back the high-speed serial using 0 Ohm resistors.
