Digital control input pins:
Note: Apply adequate settings if activation is requested as described in
Example: PGEB threshold becomes +1.3V instead of –1.3V.
1. Connect all three power supplies (V
2. Configure the digital control inputs in default mode (1).
3. Connect the analog signal as formerly (same full-scale and common mode).
4. Connect the clock signal as formerly (same level and common mode).
5. Connect the high-speed acquisition system probes to the board data outputs (LVDS
6. Switch on the power supplies.
7. Apply the clock and analog signals.
