GENERAL DESCRIPTION
This document describes the AD9272/AD9273 evaluation
board, which provides all of the support circuitry required to
operate the AD9272/AD9273 in their various modes and
configurations. The application software used to interface with
the devices is also described.
The AD9272/AD9273 data sheet, available at www.analog.com,
provides additional information and should be consulted when
using the evaluation board. All documents and software tools
are available at http://www.analog.com/fifo. For any questions,
send an email to highspeed.converters@analog.com.

Figure 2 shows the typical bench characterization setup used to evaluate the ac performance of the AD9272/AD9273. It is critical that the signal sources used for the analog input and clock have very low phase noise (<1 ps rms jitter) to realize the optimum performance of the signal chain. - Page 4 UG-001 WALL OUTLET 100V TO 240V AC 47Hz TO 63Hz SWITCHING POWER SUPPLY SWITCHING POWER SUPPLY SIGNAL SYNTHESIZER ANALOG INPUT SPECTRUM ANALYZER CW OUTPUT AGILENT POWER SUPPLY GAIN CONTROL INPUT Evaluation Board User Guide 6V DC 2A MAX SIGNAL SYNTHESIZER OPTIONAL CLOCK SOURCE Figure 2.

DEFAULT OPERATION AND JUMPER SELECTION SETTINGS This section explains the default and optional settings or modes allowed on the AD9272/AD9273 Rev. A evaluation board. Power Circuitry Connect the switching power supply that is supplied in the evaluation kit between a rated 100 V ac to 240 V ac wall outlet at 47 Hz to 63 Hz and P701. - Page 6 UG-001 Evaluation Board User Guide between the AD9272/AD9273 CWDx± outputs and the AD8339 inputs. DOUTx+, DOUTx− If an alternative data capture method to the setup described in Figure 2 is used, optional receiver terminations, R701 to R710, can be installed next to the high speed backplane connector.

Evaluation Board User Guide EVALUATION BOARD SOFTWARE QUICK START PROCEDURES This section provides quick start procedures for using the AD9272/ AD9273 either on the evaluation board or in a system level design. Both the default and optional settings are described. - Page 8 In the Global tab of the SPI Controller, find the CHIP GRADE(2) box. Use the drop-down box to select the correct speed grade, if necessary. See the AD9272 or AD9273 data sheet, the AN-878 Application Note, and the AN-877 Application Note for reference.
- Page 9 Figure 10. SPI Controller, CHIP GRADE(2) Box In the ADCBase 0 tab of the SPI Controller, find the HIGHPASS(2B) box. Click Manual Tune to calibrate the antialiasing filter. See the AD9272 or AD9273 data sheet, the AN-878 Application Note, and the AN-877 Application Note for reference.

Note that the CWD0±/CWD1±/CWD6±/CWD7± outputs are configured and biased to interface with the evaluation board. The AD9272/AD9273 is specially designed to snap onto the AD8339 evaluation board to allow the user to evaluate a larger portion of this common signal chain. For detailed instructions about enabling this function, send an email to highspeed.converters@analog.com. - Page 11 Evaluation Board User Guide Figure 18. SPI Controller, MODES(8) Box In the ADC x tab of the SPI Controller, where x is the channel to which an analog input is applied, find the CROSSPOINT SWITCH(2D) box. From the Crosspoint Switch Modes drop-down box, select the cwd2p/n option (see Figure 19).
