Multipurpose Data Interface Board (DIB)
Abstract
Defence Research Establishment Ottawa is pursuing an in-house research activity in spread-sprectrum technology to support development of robust, anti-jam satellite communications for the military. The in-house effort consists of developing a system simulator, including both a ground terminal processor and a payload processor, to research techniques involved in spread-spectrum synchronization. For these experiments, a multipurpose data interface board is required for different data operations, and is the subject of this report. The board is composed of mainly an erasable programmable logic device to reduce the number of integrated circuits and to add flexibility to the design. The board was designed to perform three functions. The first function is the data format conversion between a ground terminal processor and a data source, and likewise, a payload processor and a data sink. The second function is to provide an interface to a separate direct link between the payload and ground terminal subsystems for transmitting a reference pulse for synchronization. The third function is to provide a set of debug latches for the user. In this document, the software and hardware details are provided along with a user's guide for the board.
