Up Sampler
     
       
         
  Converts complex baseband I-Q signal @ Fsymbol rate to complex baseband or IF I-Q signal @ Fclock DAC. Up Sampler  
         
Description

The MVD UPSAMPLER core is a drop-in module that includes the following functions:
  • RRC filter for J83 cable application
  • Half-Band filters to interpolate the signal
  • Rate Converter to adjust the signal’s rate from 1.0 to 2.0
  • Optional gain multiplier
  • Optional Intermediate Frequency multiplier
  • Output for complex DAC (2 x 16 bits)

  Features

  • Converts complex baseband I-Q signal @ Fsymbol rate to complex baseband or IF I-Q signal @ Fclock DAC
  • Compliant with all our cable and terrestrial modulators (DVB-C J83A/C, J83B, ATSC, DVB-T/T2)
  • Drop-in module for Spartan-6™, Virtex-6™, Artix-7™, Kintex-7™, Virtex-7™ and
    Zynq™ FPGAs
  • Dual clock (1x,2x), CLK 1x frequency equal to DAC clock frequency (up to 160 MHz)
  • Includes Symbol rate generator
  • Programmable RRC filter for cable modulators (J83B : 0.12 or 0.18, DVB-C/J83A : 0.15, ISDBC/J83C : 0.13)
  • Programmable symbol rates for cable modulators (from 5MSymb/s to 7MSymb/s)
  • Programmable output bandwidth for DVB-T/T2 (5, 6, 7 or 8 MHz)
  • Complex baseband or IF outputs (2 x 16 bits) @ Fclock DAC
  • Fully synthesizable RTL VHDL design (not delivered) for easy customization
  • Design delivered as Netlist
  • SNR > 60dB
Applications

The UPSAMPLER is recommended for using DAC which has no upsampling stage. The application is for digital TV transmission system requiring low noise and filter adjustment stages.
