The readout rates required for the next generation pixel detectors to be used in the ATLAS and CMS experiments at the High-Luminosity LHC (HL-LHC) will be about 3 Gb/s/cm2. The very high radiation levels and small space available makes it impossible to envisage optical conversion on chip, which should be done using electrical links, implying that a significant material contribution will be associated with data transport out of the detector volume. In this contribution we will present the results of an implementation of a lossless arithmetic data compression that achieves an efficient bandwidth reduction. We will discuss the performances of the algorithm and its integration in the data output.
