Abstract :
In this contribution we present a multichannel readout board designed to replace the old A-RX board of the LHCb experiment, called TELL1 and no longer available, able to readout and process up to 8 BEETLE chips. The new version includes doubled readout channels. The sampling speed is increased, with respect to the old A-RX boards, by redesigning the board with newer serial ADCs, which are managed by the more powerful Kintex-7 FPGA. The FPGA acts also a pre-processing stage, with zero suppression and data reordering. The realized boards are used to readout data from a Cosmic Ray Telescope, which is in the development stage. Each board is able to readout 1024 channels simultaneously at the rate of 1.25 MHz, which is more than enough for the application.
