Figure 26. Reference Buffer Equivalent Circuit and Exter-
nal Decoupling Recommendation
For best results in both noise suppression and robustness
against crosstalk, the 4 capacitor buffer decoupling arrangement
shown in Figure 26 is recommended. This decoupling should
feature chip capacitors located close to the converter IC. The
capacitors are connected to either IREFT/IREFB or QREFT/
QREFB. A connection to both sides is not required.
DRIVING THE AD9201
Figure 27 illustrates the use of an AD8051 to drive the AD9201.
Even though the AD8051 is specified with 3 V and 5 V power,
the best results are obtained at
±
5 V power. The ADC input
span is 2 V.
