Texas Instruments provides a recommended PCB layout in the ADS5263IRGCR-NM evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The optimal analog input filter design depends on the specific application requirements, such as signal frequency, amplitude, and noise levels. Engineers can use tools like the TI FilterPro software or consult with TI's application engineers to design a custom filter that meets their specific needs.
While the datasheet specifies a maximum clock frequency of 125 MSPS, the actual maximum clock frequency may be limited by the specific application requirements, such as the analog input frequency and the desired signal-to-noise ratio. Engineers should consult with TI's application engineers to determine the optimal clock frequency for their specific application.
The ADS5263IRGCR-NM has an internal calibration mechanism, but engineers may need to perform additional calibration steps depending on their specific application requirements. TI provides calibration guidelines and tools, such as the ADS5263IRGCR-NM calibration software, to help engineers optimize the device's performance.
Texas Instruments recommends a multi-point decoupling scheme, with a combination of ceramic and electrolytic capacitors, to ensure stable power supply voltage and minimize noise. The specific decoupling scheme may vary depending on the application requirements and PCB layout.
