Description
The LXD21K4 provides four 16-bit D/A channels with up to 310 Msps data rate and a 1.24 Gsps update rate. This is the only FMC card on the market to offer this number of channels with LVDS digital signalling interfaces. The design is based on the Analogue devices AD9142A digital to analogue converters.
Analog input and output
Depending on the application requirements it is possible to order the LXD21K4 with either a DC coupled or an AC coupled analogue front end. The DC coupled interface is meant for signal acquisitions and playback in the first Nyquist zone while the AC coupled inputs also offer the option for signal acquisition and playback in the second Nyquist zone.
16 bit
The DAC offers 16-bits resolution further contributing to achieving best in class signal to noise ratios.
LVDS signaling
The DAC devices make use of LVDS signalling for their data interfaces. This allows easy integration of the LXD21K4 into user FPGA designs without the need to acquire expensive and complex JESD204B interface cores. Thanks to the low pin count implementation the LXD21K4 will work on all Xilinx development boards as well as the Logic-X FPGA FMC carrier boards.

Clock tree
The onboard low noise clock generator ensures easy integration into small single board systems as well as standalone operation. For larger systems, it is possible to easily synchronize multiple boards by providing an external reference clock. This is a special feature offered by the onboard clock PLL.
