Both the input pin (Pin 1) and the output pin (Pin 9) leave the IADJ pin (Pin 4) open for ful bias operation. For bias of the ADCA3990 are matched to 75 Ω. Pin 5 is the VCC pin, control on the ADCA3990 supply current, apply an external which requires 34 V for typical operation, and can support as control voltage between 0 V and 1 V at the IADJ pin.
