Stimulus (Generator) Termination
All ECL outputs need to be terminated to V TT (V TT =
V CC – 2.0 V = GND) via a 50 W resistor. The current board
design utilizes the space for placement of the external
termination resistors. (More information on termination is
provided in AN8020). The 0402 chip resistor pads are
provided on the bottom side of the evaluation board. Solder
the chip resistors to the bottom side of the board between the
appropriate input of the device pin pads and the ground pads
as shown in Figure 5 (for split power supply setup, PCB is
assembled in this configuration).

Figure 5. Expanded Bottom View
Likewise for CML outputs, CML stimulus signal need to
be terminated to V CC via a 50 W resistor. To accomplish this
configuration the external termination resistor has to be
moved from SMA_GND ring to V CC ring on the bottom of
the board.
For the LVDS configuration Input pin pads of the D0 or
D1 input has to be shorted using 100 W resistor across
differential lines.
oscilloscope to be used as a termination of the signals (in
split power supply setup SMA_GND as a system ground,
V CC , and V EE are varied; see Table 1, Power Supply Levels).
Board Components Configuration
The NB4N11MDTEVB evaluation board requires six
side SMA connectors. Placement locations are described in
the Table 2 below.
DUT Termination
For standard lab setup and test, a split (dual) power supply
is required enabling the 50 W internal impedance in the
