Atin, This was done on purpose to make the routing easier on the EVM. This is not a problem since there is only one device in this link. The JESD204B standard is just looking for a rising edge on SYSREF. This would be a problem if there were several DAC devices involved and some of the DAC's had the signals routed correctly and others had the P/N swapped, as the rising edges would no longer line up properly. Regards, Jim
