Features

  • Two balun-coupled output networks per DAC output allowing singled ended signal evaluation
  • A 5MHz to 10GHz low band balun for first Nyquist evaluation
  • A 2GHz to 18GHz high band balun for second and third Nyquist evaluation
  • A LMK04828 clock distribution chip for distributing FPGA reference clocks and SYSREF for subclass 1 operation
  • A balun-coupled clock input network to test the DAC performance with an external low-noise clock source
  • An FMC+ with high-speed serial data connections for full JESD204C testing of all 16 lanes
  • A USB to serial chip to allow programming of the DAC or LMK with a simple USB connection
  • The ability to program the DAC or LMK from an FPGA using the FMC+ connector
  • Device register programming through USB connector and FTDI USB-to-SPI bus translator with option to program from FGPA using SPI through FMC+ connector
