3.4 OUTPUT AMPLITUDE ADJUSTMENT
The output amplitude of the GS9068 can be adjusted by
changing the value of the R
SET
resistor as shown in Figure 2
and Table 1 below. For an 800mV
p-p
output with a nominal
±7% tolerance, a value of 750
is required. A ±1% SMT
resistor should be used.
Fig. 2 Output Amplitude Adjustment
The R
SET
resistor is part of the high speed output circuit of
the GS9068. The resistor should be placed as close as
possible to the R
SET
pin. In addition, the PCB capacitance
should be minimized at this node by removing the PCB
groundplane beneath the R
SET
resistor and the R
SET
pin.
NOTE: For reliable operation of the GS9068 over the full
temperature range, do not use an R
SET
value below 573
.
4. APPLICATION REFERENCE DESIGN
4.1 PCB LAYOUT
An FR-4 dielectric can be used, however, controlled
impedance transmission lines are required for PCB traces
longer than approximately 1cm. Note the following PCB
artwork features used to optimize performance:
The PCB groundplane is removed under the GS9068
output components to minimize parasitic capacitance.
The PCB ground plane is removed under the GS9068
R
SET
pin and resistor to minimize parasitic capacitance.
Input and output BNC connectors are surface mounted
in-line to eliminate a transmission line stub caused by a
BNC mounting via high speed traces which are curved
to minimize impedance variations due to change of PCB
trace width.
