It will be adjusted automatically based on the VID input amplitude level. The output VOD level set by DEMA/B[1:0] is dependent on the VID level and the frequency content. The DS125BR800A repeater in SAS3 and GEN3 mode is designed to be transparent, so the TX-FIR (de-emphasis) is passed to the RX to support link training.
