QUICK START LAB SET-UP USER’S GUIDE
Pre-Power-Up
1. The NB3N1200K and NB3W1200L have positive
power supply pins VDD and VDDIO. Connect
power supply cables to VDD, VDDIO and GND
banana jacks; (do not turn power on, yet)
2. Connect a signal generator to the SMA connectors
for the CLK_IN & CLK_IN# inputs
.
3. 50-ohm termination resistors are installed for
a signal generator on the board. Set appropriate
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
a jumper on pin 6 to easily select between High
and Low. See Figure 8.
5. The 100M_133M# and HBW_BYPASS_LBW
pins need to be hardware selected with jumpers.
See Figures 4 and 7.
6. To monitor the DIF_n/DIF_n# outputs, connect the
DIF_n/DIF_n# outputs to the appropriate
oscilloscope.

Power -Up Sequence
1. Turn on power supply, 3.3 V (VDD & VDDIO).
2. Move PWRGD/PWRDN# jumper from Low to
logic High, PWRGD position.
3. Turn on the Differential Clock Signal for the
CLK_IN inputs. The differential Clock signal for
the CLK_IN inputs can be ON or active before or
after PWRGD is set HIGH.
4. Monitor DIF_n/DIF_n# outputs on oscilloscope.
Optional
Graphical User Interface
(see page 7)
There is a stand-alone Graphical User Interface software
package and user’s manual that will interface with the DUT
via the USB connector.
1. Connect the USB port on the evaluation board to
a USB port on the PC via cable.
2. See the stand-alone GUI instructions document.
3. Allow Windows to install the necessary drivers for
the eval board USB interface hardware.
4. Start the GUI program.
