Hi Trushal, The TI devices typically use a parameter called 'KM1' (K minus 1), while the JESD IP uses K. As a result, it should be 4 for the JESD IP. Regards, Ameet

Hi Trushal, Yes, you can connected two 4 lane links (ADCs) to a single JESD IP configured for 8 lanes (with the SYNCn fanned out to both ADCs, as you have done). For this to work, the ADC's will need...
