ADC Clock Configuration
In this demonstration the FO pin is connected to GND (FO = 0V), as a result the converter uses its
internal oscillator and the digital filter first null is located at 60Hz.
The clock source in SPI transition is configured as External Serial Clock Operation mode by
keeping the SCK pin to low at the falling edge of CS pin.
ADC SPI Transmission
Figure 5–30
shows the data timing for SPI transmission. The SDI signal is used to serialize data
from the FPGA to ADC, and the SDO signal is used to serialize data from ADC to FPGA.
