3.5 Output Amplitude Adjustment  
The output amplitude of the GS1528 can be adjusted by changing the value of the RSET  
resistor as shown in Figure 3-4 and Table 3-1. For an 800mVp-p output with a nominal  
±7% tolerance, a value of 750Ω is required. A ±1% SMT resistor should be used.

Figure 3-4: Output Amplitude Adjustment  
The RSET resistor is part of the high-speed output circuit of the GS1528. The resistor  
should be placed as close as possible to the RSET pin. In addition, the PCB capacitance  
should be minimized at this node by removing the PCB ground plane beneath the RSET  
resistor and the RSET pin.

NOTE: For reliable operation of the GS1528 over the full temperature range, do not use  
an RSET value below 573Ω.
