Next generation functional components for space telemetry data processing

The use of new design methodologies to continue the evolution of telemetry data systems to higher levels of integration is discussed. In particular, hardware description languages and automated logic synthesis tools are used to create very dense Application Specific Integrated Circuits (ASICs) that generically implement telemetry processing functions. The use of the ASICs will make it possible to develop a new generation of functional components, each of the components integrating several telemetry processing subsystems into a single card.

Frame synchronization at 300 Mbps and beyond

A prototype frame synchronizer card and its supporting VLSI components under development at the Goddard Space Flight Center that will operate at a minimum 300 Mbps while providing a full suite of programmable functions are presented. Cumulative quality data generation, onboard self diagnostics, and status/control processing are all integrated in this single card design. Consideration is given to the telemetry frame synchronizer subsystem and high-rate frame synchronizer specifications.
