DESCRIPTION:Speakers: Dr. HAMPSON\, Grant (CSIRO)\nBluering is the CSIRO n
 ame given to a new generation of radio astronomy array receivers based on 
 Xilinx’s Radio Frequency System on Chip (RFSOC) technology. Bluering was
  initially designed for low frequency radio astronomy applications (such a
 s the MWA telescope)\, but has grown to be a receiver also capable of L-ba
 nd radio astronomy (such as Phased Array Feeds).  Bluering is not only an 
 array receiver\; the spare FPGA resources can be used to form multiple wid
 eband beams\, compute the array covariance matrix\, RFI mitigation\, and e
 ven pulsar timing. \n\nTo enable many types of astronomy receiver applicat
 ions an RF daughter board\, called Taipan\, can be customised to have coax
 ial and fibre inputs. Available to each Taipan is a tuneable LO signal (wh
 ich can double the number of RF inputs for some frequencies)\, attenuator 
 control bits as well as a calibration signal. With all these features it i
 s possible to customise the Taipan to most astronomy applications.\n\nCSIR
 O has developed a prototype Bluering system based around the 16 input 2GSP
 S 12-bit ADC version of the RFSOC. This paper presents some of the design 
 details\, including liquid cooling\, RFI shielding\, optical timing\, embe
 dded control system\, as well as signal processing and communications firm
 ware. Prototyping results are also presented - in particular RFI shielding
 \, power\, weight\, SNR\, etc. will be shown. Following the development an
 d testing of this initial version CSIRO is planning on building a second v
 ersion (without some of the bugs!) and aims to improve the general perform
 ance of the system.\n\nhttps://events.mpifr-bonn.mpg.de/indico/event/154/s
