AbstractA high speed Synchronizer Card utilizing semi-custom and custom very large scale integration (VLSI) devices, microprocessor control, and programmable logic has been designed to provide a generic NASA Communication (NASCOM) block processing and telemetry frame synchronization function for present missions and Space Station era telemetry data streams at data rates up to 25 Mbps. The Synchronizer Card utilizes four distinct sets of VLSI semi-custom and custom chips to shrink all of the functions required for NASCOM block processing, telemetry frame synchronization, real time quality trailer appendage and cumulative quality statistic generation into a single Synchronizer card. This paper will describe the functions performed by the Synchronizer Card and each individual set of chips.
