The devices listed above have the option of being driven
single
−
endedly by using the provided V
BB
pin of the device.
In order to drive it single
−
endedly, Configuration 2 needs to
be modified.
1. Remove the 50
W
chip resistor from R3.
2. Short pin 3 and pin 4 together.
Option A) Short R3 and R4 trace pads.
Or
Option B) Place a SMA connector on J4 and use
a cable with SMA connectors to short
J3 and J4 connectors.

This device has an option of being 50
W
terminated
internally. To evaluate the internal 50
W
resistor of the
device, Configuration 2 needs to be modified.
1. Remove the 50
W
chip resistors from R2 and R3.
2. Short R1 and R4 to V
TT
(GND).
Option A) Short R1 and R4 to V

MC100LVELT23
The TTL output data presented in the data sheet are obtained
under 500
W
load resistor in parallel with 20 pF fixture
capacitance. In order to obtain comparable data as in the data
sheet, the evaluation board needs to be modified.
1. Cut the output trace so that the 0402* size chip
resistor can be placed over the cut out trace.
2. Solder a 450
W
chip resistor across the cut out
trace.
*Any size chip resistor can be used. The recommended size of the
chip resistor is 0402, to reduce the effect of parasitic with a 17 mil
trace width. 450
W
in series with 50
W
instrument resistance add up
to 500
W
loaded condition.
