GENERAL DESCRIPTION
The AD9146 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1000 MSPS with nominal supplies and 1230 MSPS with increased supplies, permitting multicarrier generation up to the Nyquist frequency.

FEATURES
   Flexible LVDS interface allows byte or nibble load
   Single-carrier W-CDMA ACLR = 80 dBc at 122.88 MHz IF
   Analog output: adjustable 8.7 mA to 31.7 mA, RL = 25 Ω to 50 Ω
   Integrated 2×/4× interpolator/complex modulator allows
      carrier placement anywhere in the DAC bandwidth
   Gain, dc offset, and phase adjustment for sideband
      suppression
   Multiple chip synchronization interfaces
   High performance, low noise PLL clock multiplier
   Digital inverse sinc filter
   Low power: 1.2 W at 1.0 GSPS, 800 mW at 500 MSPS,
      full operating conditions
   48-lead, exposed paddle LFCSP
