AD9739BBCZ

AD9739 is a 14bit, 2.5GSPS high performance RF digital to-analogue 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 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. Application includes broadband communications systems, military jammers, instrumentation, automatic test equipment, radar, avionics.
