2.1 ADS9218 Device Connections

The digital communications lines for the ADC (shown in Figure 2-1) all follow the low-voltage differential signaling (LVDS) standard and are connected with optional termination resistors. A digital serial peripheral interface (SPI) port is used to configure registers in the device. The SDO output line includes a termination.
