Digital RF Up Converter for AD9739/A DAC
     
       
         
  Converts multiple baseband I-Q signals to analog RF signal with AD9739 or AD9739A 14-bit RF DAC sampled at up to 2.5 GHz Digital RF Up Converter for AD9739A DAC  
         
Description

The MVD Upconverter core is a drop-in module that includes the following functions :
  • An Interpolation x16 + RF Modulation per each independent RF channel
  • An Output Processing module which combines up to 32 independent RF interpolator channels
  • A clock management module
  • An OSERDES module which connects the LVDS IO to the RF DAC
  • A CPU BUS to configure the parameters of the Upconverter

  Features
  • Drop-in module for Spartan-6, Virtex-6, Artix-7, Kintex-7 and Virtex-7 FPGAs
  • Provides direct RF synthesis for baseband I-Q signals (DC to 1.25 GHz)
  • Support for 2nd and 3rd Nyquist zone for carriers frequencies up to 3GHz+
  • Includes clock management module
  • Very low FPGA resources required
  • 32 or 64 MHz minimum bandwidth per RF channel
  • In-band ripple < 0.2 dB and SNR > 75dB
  • Carrier frequency dynamically adjustable with sub-Hertz precision
  • Dual 14-bit LVDS output busses directly tied to AD9739/A input data pins (compatible with 11-bit for AD9737A)
  • Can be modified for using others RF DAC (please contact MVD)
  • Fully synthetizable RTL VHDL design (not delivered) for easy customization
  • Design delivered as Netlists + VHDL design example
Applications

The Upconverter for AD9739/A is recommended for digital TV transmission and other telecommunication systems requiring low noise and adjustment free RF stages.
