The AD9739 is a 14-bit, 2.5 GSPS high performance RF digital-to-analog converter (DAC) capable of synthesizing wideband signals from dc up to 3.0 GHz. Its DAC core features a quad-switch architecture that provides exceptionally low distortion performance with an industry-leading direct RF synthesis capability. This feature enables multicarrier generation up to the Nyquist frequency in baseband mode as well as second and third Nyquist zones in mix mode. The output current can be programmed over the 8.66 mA to 31.66 mA range.
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. Multichip synchronization is possible with an on-chip synchronization controller. A serial peripheral interface (SPI) is used for device configuration as well as readback of status registers.
The AD9739 is manufactured on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V supplies. It is supplied in a 160-ball chip scale ball grid array for reduced package parasitics.
