3.1.1 Digital Interface Connections

The ADS9327 uses an SPI that configures internal device registers and consists of SCLK, SDI, D[3:0], and CSn. Configure the SPI to 1-lane, 2-lane, and 4-lane options to capture data. All of the SPI signals connect to the FMC connector on the EVM. Figure 3-1 provides the FMC connector signal definition. These signals are also available through test points for scope measurements, as indicated in the PCB silkscreen.

The FMC connector pin-out in Figure 3-1 interfaces with standard FPGA development kits.

Note: The TI-provided software GUI is only compatible with the TSWDC155EVM. Third-party software development is not supported.
