© National Instruments Corporation 21 NI 5762R User Guide and Specifications
External Sample clock
Input frequency range ....................................150 MHz to 250 MHz
External Reference clock
Input frequency ..............................................10 MHz
Default Settings
All specifications are measured with a default ADC reference setting of 2.5 V unless otherwise
specified. The ADC reference can be configured to values from 2.0 V to 2.5 V. You can optimize the
SNR and SFDR over various input frequencies and bandwidths by adjusting the ADC reference and
buffer current settings.
Note
For more information about the supported analog input ranges and buffer currents, refer to
pages 19 and 23 of the AD9467 data sheet available at
www.analog.com.
