NB3N1200KMNGEVB, NB3W1200LMNGEVB
NB3N1200K/NB3W1200L Evaluation Board User'sManual
Introduction
The NB3N1200KMNGEVB and the NB3W1200LMNG EVB evaluation boards were developed with a common PCB layout design to accommodate the NB3N1200K (standard HCSL outputs) and the NB3W1200L (HCSL Push-Pull outputs) devices. Each board comes fully assembled and tested and is ready to evaluate in the lab. This evaluation board was designed to provide a flexible and convenient platform to quickly evaluate, characterize and verify the operation of the NB3N1200K or NB3W1200L devices. To minimize the board size, six differential outputs are accessed with SMA connectors. The other six differential outputs are loaded, terminated and can be monitored with ahigh impedance probe as explained later in the manual.
The NB3N1200K Evaluation Board schematic is the same as the NB3W1200L schematic except the “1200L” has some components depopulated (DNI) per the “1200L” BOM.

EVAL BOARD USER’S MANUAL
The NB3W1200LMNGEVB does not have RP resistors
installed on its differential Push-Pull outputs.
The NB3W1200LMNGEVB does not have
FB_OUT/FB_OUT# resistors installed.
The NB3W1200LMNGEVB does not have R
resistor R107 installed.
This manual should be used in conjunction with the device datasheet which contains full technical details on the device specifications and operation.

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.

Power Supplies
Each VDD, VDDIO and GND power supply has
a separate side-launch banana jack located on bottom side.
This board is capable of measuring device IDD & IDDIO
separately.
Board Layer #2 = SMA Ground = Device GND = 0 V.
GND Banana Jack = negative power supply for DUTGND and SMAGND. Exposed Pad (EP): The exposed pad footprint on the board is soldered to the exposed pad of the QFN-64 package, and is electrically connected to GND power supply.
Board Layer #3 = VDD and VDDIO Power Supplies
VDD = positive power supply for core and inputs; VDD/VDDA/VDDR (pins #1, 8, 24, 40, 57)
VDDIO = positive power supply for outputs; VDDIO (pins #25, 32, 49, 56)
VDD & VDDIO have the power supply filtering per
datasheet by the banana jacks.
All VDD/VDDA/VDDR/VDDIO device pins have a 0.1 mF bypass capacitor installed on top side next to package pins.
Control Pins
Each control pin can be managed manually with a H/L
jumper header; H = VDD, L = GND.
Tri-Level Input Pins - HBW_BYPASS_LBW#, SA0 and SA1
The three tri-level input pins, HBW_BYPASS_LBW#, SA0 and SA1, have selectable (with jumper) 4.7 k-ohm pull-up to VDD and 4.7 k-ohm pull-down to GND resistors; No jumper defaults to open/float.
For a HIGH Level – Put Jumper to High
For a LOW Level − Put Jumper to Low
For a MID Level − Put Jumper to both High and Low;
this will Enable both Pull-up and Pull-down Resistors
HBW_BYPASS_LBW#
At J65 and J66 headers, there is a 4.7 kW pull-up to VDD and a 4.7 kW pull-down resistor to GND for manual control. See Figure 4.
SA0 & SA1
At J67 and J69 headers, there are 4.7 kW pull-ups to VDD and at J68 and J70, there are 4.7 kW pull-down resistors to GND for manual control. See Figure 5.

OE_n# Pins (Output Enable/Disable Function)
Six of the twelve differential outputs that have metal traces going to SMA connectors have OE_n# pins on the left side of the board that can be controlled manually using the convenient High/Low OE_n# jumpers. See Figure 6.
