GENERAL DESCRIPTION
The AD9142 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency.

FEATURES
   Very small inherent latency variation: <2 DAC clock cycles
   Proprietary low spurious and distortion design
      6-carrier GSM ACLR = 79 dBc at 200 MHz IF
      SFDR > 85 dBc (bandwidth = 300 MHz) at ZIF
   Flexible 16-bit LVDS interface
      Supports word and byte load
   Multiple chip synchronization
      Fixed latency and data generator latency compensation
   Selectable 2×, 4×, 8× interpolation filter
      Low power architecture
      fS/4 power saving coarse mixer
   Input signal power detection
      Emergency stop for downstream analog circuitry
         protection
   FIFO error detection
   On-chip numeric control oscillator allows carrier placement
      anywhere in the DAC Nyquist bandwidth
   Transmit enable function for extra power saving
   High performance, low noise PLL clock multiplier
   Digital gain and phase adjustment for sideband suppression
   Digital inverse sinc filter
   Supports single DAC mode
   Low power: 2.0 W at 1.6 GSPS, 1.7 W at 1.25 GSPS, full
      operating conditions
   72-lead LFCSP

APPLICATIONS
   Wireless communications: 3G/4G and MC-GSM base stations,
      wideband repeaters, software defined radios
   Wideband communications: point-to-point, LMDS/MMDS
   Transmit diversity/MIMO
