Abstract
The Uniboard is a project for a general purpose board, containing several large FPGAs, to be used as a general component for the next generation VLBI correlator. The Digital Receiver Working package deals with the implementation of a wideband frequency demultiplexer, that divides the received radio band (up to a bandwidth of 8 GHz) into enough narrow band channels (64 MHz bandwidth or lower) to completely cover it. Each channel can be independently positioned across the input band, and may have a different bandwidth and signal representation (number of bits per sample).
The document describes the programing model for the hardware components in the board.
