Equipment Needed
Signal Generators
Analog signal source: The frequency and power requirements depend on the tests to be performed. A bandpass filter is typically used for single tone tests.
Analog clock source: The clock signal generator should have very low phase-noise and be capable of supplying a 10Ghz clock signal (or 6
GHz clock signal for the the 6Gsps speed grade of AD9213) at approximately 10dBm.
Reference clock source: For AD9213-10GEBZ with 16 output lanes (at 10Gsps), the frequency of REFCLK is 625MHz. For AD9213-6EBZ configured for 8 output lanes (at 6Gsps), the frequency of REFCLK is 750MHz. For AD9213, the frequency of REFCLK is the digital output lane rate divided by 20. For AD9217, the frequency of REFCLK is the sample rate divided by 16, which is the same as digital output data rate divided by 16.

Close ACE.
Install jumpers on P3, P8, P9, P10 as shown below.
You can install standoffs at the locations (marked with an *) if needed. Alternatively, you can use foam sheets to support the board.
Connect the AD9213 evaluation board to the regulator board. The connectors mate as shown below. With the boards parallel to each other, carefully align the connectors.
Press the boards together applying even pressure over the connectors to avoid stressing and flexing the boards. The connectors are keyed; therefore, you cannot insert the board with the incorrect orientation.
Connect the AD9213/9217 evaluation/regulator board combo to the ADS8-V1EBZ board together as shown in the following figure.
Align the FMC+ connectors and apply even pressure across the connector and press the FMC connector on to its counterpart on the FPGA board.
Connect signal, clocks, power, and
USB cables to the boards as shown in Figure 1.
Signal (J3): The frequency and amplitude of the test signal depend on the type of test you are performing. Full scale is typically achieved at 9dBm – 12dBm signal power at the signal generator (depending on the frequency). If in doubt about which amplitude to use, start with a lower amplitude (for example, 4dBm at the signal generator) and work up or down from there.
Note: In Figure 1 the input signal is shown being applied to RF connector J3. The trace from J3 goes to the balun where the single-ended signal is converted to differential. On some board revisions the trace to the balun comes from RF connector J2. In these cases, the input signal must be applied to J2.
Sample clock (J13): The sample clock works well across a wide range of amplitudes (1dBm – 10dBm at the signal generator). Because jitter performance is likely to improve as the slew rate increases, choose an amplitude towards the upper end of the stated range.
Reference Clock (ADS8-V1EBZ J1): Similar to the sample clock, the reference clock works well across a wide range of amplitudes (1dBm – 10dBm at the signal generator). Unlike the sample clock, the reference clock is not sensitive to jitter/phase noise. Any signal generator that meets the frequency and power requirements works. For AD9213, the frequency of the reference clock is the (output digital data rate)/20. For AD9217, the frequency of the reference clock is the (output digital data rate)/16.
Example: For the default JESD204B output configuration of AD9213-10GEBZ (L = 16, N’ = 16,
M = 1) at 10Gsps, the output data rate is 12.5Gbps. Reference clock frequency =12.5G/20 = 625MHz.
Example: For AD9213-6GEBZ, ACE brings the part up in 8-Lane mode. In this case (L = 8, N’ = 16,
M = 1) at 6Gsps, the output data rate is 15Gbps. Reference clock frequency = 15G/20 = 750MHz.
Connect the
USB cable from the ADS8-V1EBZ FPGA board to the Windows PC that has ACE installed.
Power on the ADS8-V1EBZ FPGA board using the switch S4. Wait several seconds after powering on the ADS8-V1EBZ, until DS17 flashes and the FPGA fan has stopped spinning.
Start ACE from Start→Programs→Analog Devices→ACE.
ACE will auto-detect the AD9213 or AD9217 board and bring up the correct ACE plugin, which will appear in the upper left portion of the
GUI. If the plugin does not appear in the upper left, select Plug-in Marketplace and select AD9213-10GEBZ, AD9213-6GEBZ or AD9217, and add the selected plugin.
Double click on the AD9213 or AD9217 part number in the plugin icon in the upper left of the
GUI.
“Unknown” initially appears in the lower left corner. Wait until “Unknown” changes to “Good.”
After “State=Good” appears in the lower left, turn on the signal generators for the clock, reference clock, and signal.
Double-click the AD9213/AD9217 icon to display the chip view.
