The main functions of the digital back-end (DBE) are digitizing of input signals and translation it from intermediate frequency (IF) range to baseband, 2-bits quantizing, formatting the data into VDIF-frames and transmitting VDIF-frames to storage system by 10 G Ethernet link.
The DBE has four channels. The bandwidth of the channels could be 512 MHz or 1024 MHz depending on the required mode. Input signals occupies the IF range of 1-1.5 GHz or 1-2 GHz. Digitized data are captured by FPGA and processed by it. The DBE unit is able to process four 512 MHz bandwidth channels or two 1024 MHz bandwidth channels. The 2-bits output data streams are transmitted to storage system as VDIF frames by fiber-optic links. The DBE output data rate is 8 or 16 Gbit/s. The DBE has small size and weight and could be mounted on the antenna near to outputs of microwave frequency convertors.
