(RIKEN) we have tested operating the DDS with 16 full channels. We found out that there was a problem with power distribution. The current drawn by the board was large enough to create substantial voltage drop in the power line that runs underneath the PCI sockets. A hot-fix that Yamaguchi-san (RIKEN's researcher) did was to route the power line directly underneath each PCI connector.
Next breakout board should have wider trace for power delivery.
Also it might be better to ground the digital and analog power supply right on the breakout board.

BNC connection for AUX CLK IN is actually connected to the SYS_CLK_4 output of the PLL of the XEM6010 module. Need to correctly route this to the CLK_IN of the FPGA board in the later version.
