Getting Started

This section provides quick start procedures for using the evaluation board for AD9680 or AD9234.

Configuring the Board

Before using the software for testing, configure the evaluation board as follows Connect the evaluation board to the ADS7-V1EBZ data capture board, as shown in Figure Connect one 12V, 6.5A switching power supply such as the CENB1080A1251F01 supplied to P4 on
the ADS7-V1EBZ board. Connect the Standard-B USB port of the ADS7-V1EBZ board to the PC with the supplied USB cable. Turn on the ADS7-V1EBZ. The ADS7-V1EBZ will appear in the Device Manager as shown in Figure

Figure Device Manager showing ADS7-V1EBZ If the Device Manager does not show the ADS7-V1EBZ listed as shown in Figure 2, unplug all USB
devices from the PC, uninstall and re-install SPIController and VisualAnalog and restart the hardware setup from step On the ADC evaluation board, provide a clean, low jitter 1GHz clock source to connector J801 and set the amplitude to 14dBm. This is the ADC Sample Clock.

On the ADC evaluation board, provide a clean, low jitter clock source to connector J804 and set the amplitude to 10dBm. This is the Reference Clock for the gigabit transceivers in the FPGA. The REFCLK frequency can be calculated using the following empirical formulae bps/lane, where Default Nprime = 16

On the ADC evaluation board, use a clean signal generator with low phase noise to provide an input signal for channel A to P200. Use a shielded, RG-58, 50 coaxial cable to connect the signal generator output to the ADC Evaluation Board. For best results, use a narrow-band, band-pass filter with 50 terminations and an appropriate center frequency. ADI uses TTE, Allen Avionics, and K & L band-pass filters.

On the ADC evaluation board, use a clean signal generator with low phase noise to provide an input signal for channel B to P202. Use a shielded, RG-58, 50 coaxial cable to connect the signal generator output to the ADC Evaluation Board. For best results, use a narrow-band, band-pass filter with 50 terminations and an appropriate center frequency. ADI uses TTE, Allen Avionics, and K & L band-pass filters.
