The AD9739ABBCZ is a 14-bit high performance RF Digital-to-analog Converter (DAC) capable of synthesizing wideband signals from DC up to 3GHz. The AD9739A is pin and functionally compatible with the AD9739 with the exception that the AD9739A do not support synchronization or RZ mode and is specified to operate between 1.6 and 2.5GSPS. By elimination of the synchronization circuitry, some non-ideal artifacts remain stationary on the AD9739A between power-up cycles, thus allowing for possible system calibration. The inclusion of on-chip controllers simplifies system integration. 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. A serial peripheral interface (SPI) is used for device configuration as well as read-back of status registers.
