GENERAL DESCRIPTION
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.

FEATURES
   Direct RF synthesis at 2.5 GSPS update rate
      DC to 1.25 GHz in baseband mode
      1.25 GHz to 3.0 GHz in mix mode
   Industry leading single/multicarrier IF or RF synthesis
      fOUT = 350 MHz, ACLR =80 dBc
      fOUT = 950 MHz, ACLR = 78 dBc
      fOUT = 2100 MHz, ACLR = 69 dBc
   Dual-port LVDS data interface
      Up to 1.25 GSPS operation
      Source synchronous DDR clocking
   Pin-compatible with the AD9739A
   Multichip synchronization capability
   Programmable output current: 8.7 mA to 31.7 mA
   Low power: 1.16 W at 2.5 GSPS

APPLICATIONS
   Broadband communications systems
   Military jammers
   Instrumentation, automatic test equipment
   Radar, avionics
