Abstract The ever growing demand for on-board space craft 3 PULSE GENERATION METHODS processing combined with the exponential advance in chip 4 ANALOG TO DIGITAL CONVERTERS AND SAMdevelopment and high pin count devices is resulting in an PLING TECHNIQUES increased complexity in high reliability interconnect technology. When the thermal management, control of ground 5 DIGITAL HARDWARE CAPABILITIES AND LIMIbounce, and power distribution issues are considered, achiev-TATIONS ing the required reliability levels for space applications with 6 RF COMPONENTS traditional interconnect technologies is becoming more of a 7 UWB BASEBAND ALGORITHMS concern. As an alternative solution, an ultrawideband (UWB) based high speed wireless method for chip to chip as well as 8 CONCLUSIONS AND FURTHER RESEARCH off-board communications can be considered.

UWB with its simple BIOG transceiver architecture, low power consumption, and high RAPHIES data rate within short ranges is shown to be the best candidate for the applications targeted. This paper explores the design challenges for developing a test-bed using commercial off-1. INTRODUCTION the-shelf (COTS) components that will be used to prove the concept of wireless chip-to-chip communications and Ultrawideband (UWB) is a promising technology for netdevelop associated algorithms. Energy detector based UWB works requiring a very high data rate at short distances. Chip transceiver is presented in this paper and our study shows the to chip, board to board, and box to box interconnects can also feasibility of implementation such transceiver using COTS make use of an UWB based wireless link. In these cases, components. The UWB transceivers will eventually be in-the distances are even shorter compared to a networking tegrated into a chip eliminating the need for many of the application, and the UWB designer can take advantage of high speed interface specific applications, and decreasing the this fact for high speed link. The physical layer requirements number of the pin fields required. for interconnects are primarily determined by the data rate needed and the tolerable bit error rate.
