A. C
L
includes probe and jig capacitance.
B. A 50- Ω termination resistor is needed to match the loading of the network analyzer.
Figure 8. Test Circuit for Crosstalk (X
TALK
)
Crosstalk is measured at the output of the nonadjacent ON channel. For example, when V
SEL
= 0 and A
0
is the
input, the output is measured at 1B
1
. All unused analog input (A) ports are connected to GND, and output (B)
ports are connected to GND through 50- Ω pulldown resistors.
