Downconverter multi-channel - 16 bit, min. 220 MHz | 64
RFELs ChannelCore core is based on a novel channelisation architecture, which provides the flexibility traditionally associated with DDC cores and ASIC devices, but with significantly greater silicon efficiency. It can process two channels of 16 bit real ADC input data at rates of over 220MHz and provide 64 channels of complex down-converted output data, with each output channel independently run-time configurable in terms of input source, centre frequency, output sample rate, filter selection and gain. The core is envisaged as a replacement for standard digital down-converter ASIC chips or FPGA cores, providing significantly higher channel capacity than is possible with currently available ASIC devices or less optimal FPGA cores. Furthermore, the core provides high quality fractional resampling, with extremely high end-to-end dynamic range of around 80dB. The filter taps for the resampler are programmable at run-time and may be programmed to provide multi-standard down-conversion.independently configurable channels.
Fits within a single Xilinx Artix / Altera Cyclone FPGA.
