POWER SUPPLY CONNECTIONS 1. The NB3N1200K and NB3W1200L have positive Device Pin power supply pins VDD and VDDIO. Connect Power Supply Connector Power Supply power supply cables to VDD, VDDIO and GND VDD 3.3 V banana jacks (do not turn power on, yet) VDDIO 1.05 V to 3.3 V 2. Connect a signal generator to the SMA connectors GND 0V for the CLK IN & CLK IN inputs. 3. 50-ohm termination resistors are installed for a signal generator on the board. Set appropriate Single Power Supply Dual Power Supplies input signal levels (HCSL input, VIL = 0 V, VIH = 700 mV, Frequency 100 or 133.33 MHz) 4. Ensure the PWRGD/PWRDN pin is in the Low state before power up (PWRDN ). There is +3.3 V 0 V +3.3 V 1.05 V to 3.3 V 0 V a jumper on pin 6 to easily select between High and Low. See Figure 8. VDDIO 5. The 100M 133M and HBW BYPASS LBW VDD, VDDIO GND VDD GND pins need to be hardware selected with jumpers. 1.05 V to 3.3 V See Figures 4 and 7. 6. To monitor the DIF n/DIF n outputs, connect the +3.3 V +3.3 V DIF n/DIF n outputs to the appropriate oscilloscope. Figure 2.
