The AD9739 is a 14-bit, 2.5 GSPS high performance RF digital-to-analog converter (DAC) capable of synthesizing widebandsignals 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 synthesiscapability. This feature enables multicarrier generation up to the Nyquist frequency in baseband mode as well as second andthird 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 thedigital interface with existing FGPA/ASIC technology. On-chipcontrollers are used to manage external and internal clock domainvariations 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 readbackof status registers.
The AD9739 is manufactured on a 0.18 μm CMOS process andoperates from 1.8 V and 3.3 V supplies. It is supplied in a 160-ballchip scale ball grid array for reduced package parasitics.
