The AD9739A is a 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from DC up to 3 GHz. A dual-port, source synchronous, LVDS interface simplifies the digital interface with existing FGPA/ASIC technology. On-chip controllers are used to manage external and internal clock domain variations over temperature to ensure reliable data transfer from the host to the DAC core.

Description:
|
|
DAC operating mode. One of the following modes can be selected:
|
|
|
|
* normal: This is DAC normal mode.
|
|
* mixed-mode: In this mode the output is effectively chopped at
|
|
the DAC sample rate. This has the effect of
|
|
reducing the power of the fundamental signal while
|
|
increasing the power of the images centered around
|
|
the DAC sample rate, thus improving the output
|
|
power of these images.
