11 / 40 page AD9882A Rev. 0 | Page 11 of 40 Table 6. Interface Selection Controls AIO (0xF Bit 2) Analog Interface Detect Digital Interface Detect AIS (0x0F, Bit 1) Active Interface Description 0 Analog Force the analog interface active. 1 X X 1 Digital Force the digital interface active. 0 X None Neither interface was detected. Both interfaces are powered down. 0 1 X Digital The digital interface was detected. Power down the analog interface. 1 0 X Analog The analog interface was detected. Power down the digital interface. 1 1 0 Analog Both interfaces were detected. The analog interface gets priority. 0 1 Digital Both interfaces were detected. The digital interface gets priority.
