Abstract
This Note is aimed at specifying the requirements for both the cryogenic LNA and the DL-FLL system for the readout of the SAFARI instrument. The major issue of this work is the amplification chain, so the development of the cryogenic LNA. By means of this device it is also possible to implement a new model for the readout system of the SAFARI instrument, called DL-FLL, based on the FDM technique. The reference document for the SPICA-SAFARI amplification chain is RD1. The baseline readout configuration is based on the so-called BBFB proposed by SRON to read array of pixels (160 Pixels per 35 channels) by the FDM technique. The Italian consortium, which is developing the DL-FLL in the X-ray case, proposed this technique to the SAFARI-consortium as a study activity for backup solution. The concept of the DL-FLL it is shown in RD2.
