Low power, TID and SEU resistant and high bandwidth upgradeable communication between computer nodes are of utmost importance for future NASA missions. The current state off-the-art binary SF interconnect architectures have high power consumption and latency due to the necessity to perform internal data conversion and synchronization in order to recognize redundant bits and extract useful information from the data stream. The high power consumption of the SFs limit their application in the next generation of nano-satellites. In order to minimize latency and reduce power consumption, we propose a novel, robust, radiation tolerant and easy-to-align SF based on a multi-level power efficient Low Voltage Differential Signal interface. Our approach uses differential multilevel signals to mark a reference high-level bit position in one of the differential channels. Because the marked pilots will follow the high logic level in one of the differential outputs, they will regularly occur at the same bit position and ensure stable and easy recovery of the low-speed clock signal, which will be used as a reference for multi-channel data alignment and will synchronize high speed clocking circuitry using a standard clock multiplier technique.

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
