SLAS553B November 2008 – August 2015 TLV320ADC3101
Each system design and PCB layout is unique. The layout must be carefully reviewed in the context of a specific PCB design. However, the following guidelines can optimize the TLV320ADC3101 performance:
The decoupling capacitors for the power supplies must be placed close to the device terminals. Figure 48 shows the recommended decoupling capacitors for the TLV320ADC3101.
For analog differential audio signals, they must be routed differentially on the PCB for better noise immunity. Avoid crossing digital and analog signals to avoid undesirable crosstalk.
Analog and digital grounds must be separated to prevent possible digital noise from affecting the analog performance of the board.
