Issue Date: | 2018 | Volume: | 2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC) | First Page: | 1 | Abstract: | A novel digital hardware platform has been designed for the Low Frequency Aperture Array (LFAA) component of the Square Kilometre Array (SKA). This board, called Analog Digital Unit (ADU), is a 6U board containing sixteen dual-inputs Analog to Digital Converters (ADC) and two Field Programmable Gate Array (FPGA) devices, capable of digitizing and processing 32 RF input signals. We present the main features of the board and the signal processing firmware that has been developed for LFAA. Although the ADU has been conceived mainly for the low frequency band (50-350 MHz), its use has been proved effective also for higher frequencies (375-650 MHz). In this paper we describe also the application of ADU as the digital acquisition and processing system for PHAROS2, a cryogenically cooled 4-8 GHz Phased Array Feed (PAF) demonstrator. The final part is focused on the future developments of the board. | Conference Name: | URSI Atlantic Radio Science Conference (URSI AT-RASC) | Conference Place: | Gran Canaria, Spain | Conference Date: | 28 May - 1 June 2018 | URI: | http://hdl.handle.net/20.500.12386/28093 | URL: | https://ieeexplore.ieee.org/document/8471592 | ISBN: | 978-90-82598-73-5 978-1-5386-3764-7 |
