Figure 5 shows a block diagram. Figure 5: The block diagram of the AD9250 shows the added device clock lines. Analog Devices has created a high speed ADC FIFO evaluation kit that includes the ADC ...

Fig. 4 is the block diagram for charging source detection. Two DACs are used to generate the 0.6V bias for the D+ and D- lines, and the voltage on the other line is measured by the ADC.
