The XU-TX is an XMC module which features two AC-coupled single-ended 16-bit DAC outputs with programmable DC bias. The DAC devices employed support synchronization, interpolation, and their unique output circuits allow improved frequency synthesis in the 2nd Nyquist zone. This can shift the Nyquist null frequency in the output spectrum to two times the typical Nyquist null frequency. The maximum sample rate of the DAC IC is 12 GSPS, the maximum external direct clocking rate is 6 GSPS and the on board PLL can generate clocks up to 4.8 GHz. The DACs' JESD 204B interfaces can stream data with transfer rates up to 6 GSPS.
