Q8J Low SWaP with GTH Computer-on-Module

There's always room for improvement, isn't there? Which is why we pushed further and created the Q8J. Taking the Q8, fine-tuning it, and adding multi-Gigabit per second transceivers for JESD204B and PCIe interfaces, and enabling access to external DDR3 or DDR4 memory. With its support of JESD204B, the Q8J enables the next generation of Software Defined Radio (SDR).

SPACE COMPUTING PRODUCTS - RELATIVE PERFORMANCE

There are many attributes and trade-offs when comparing performance between computing platforms. These graphs give an idea of how the different models compare to each other. These represent a comparison of Q-Card processor boards; daughterboards may add additional resources.

* The Q9 A72 supports out of order execution, larger cache, and faster clock speed etc.

Specific Use

In addition to our standard daughterboards, we offer application-specific development integrating our powerful Q-Card processors with the interfacing options and application-specific electronics you require. Contact our team to learn more about customization.
