3 Digital Interface

The ADS9817 uses an SPI interface to configure the registers (SCLK, SDI, SDO, CS, and SPI_EN). The
ADS9817 uses a CMOS interface for capturing conversion data for each ADC channel (D0, D1, D2, and D3).
The SPI and CMOS signals connect to the FMC connector.

Figure 3-1

provides the FMC connector signal

definition. These signals are also available on tented via test points for scope measurements. Top overlay text
indicates the location of these test points.
