Other Parts Discussed in Thread: ADS4122

Looking for ADC evaluation board which I will be able to accept input from: 

  • PC
  • Scope
  • File 

It doesn’t matter which one of them, and output the digital data to an FPGA unit.

Furthermore, I want to assert fpga output clock to ADC in order to synchronize ADC with my FPGA system. 

ADC requirements are: 

  • Min of 50MSP
  • Min of 10 bit resolution
  • 0

    Eli:

    One option is to utlize the ADS4122 12-bit 65MSPS ADC.  This device meets your sampling requirements and can be configured with an external clock input.  The output data to the FPGA can be configured for parallel LVDS or parallel CMOS.

    The input is a true analog input.  The board does not accept a digital pattern from PC or file.  Conceivably you could use the analog output of a scope to drive the analog input to the ADC.  Alternatively, you could use a file in conjunction with a DAC to generate the pattern that is fed into the ADC input.
