Texas Instruments provides a recommended PCB layout in the ADS5463IPFPR evaluation module documentation, which includes guidelines for signal routing, grounding, and decoupling. It's essential to follow these guidelines to minimize noise, ensure signal integrity, and achieve optimal performance.
The ADS5463IPFPR datasheet provides a general guideline for the analog input anti-aliasing filter. However, the optimal filter design depends on the specific application's frequency range, signal amplitude, and noise requirements. Engineers can use filter design tools, such as TI's FilterPro software, to design and simulate the optimal filter for their application.
While the datasheet specifies a maximum clock frequency of 650 MSPS, the actual maximum clock frequency may be limited by the system's clock jitter, signal integrity, and other factors. Engineers should consult with TI's application engineers or perform their own testing to determine the maximum clock frequency for their specific application.
The ADS5463IPFPR requires calibration to achieve optimal performance. Engineers should follow the calibration procedure outlined in the datasheet, which includes offset and gain calibration. Additionally, TI provides calibration software and tools, such as the TSW1405EVM, to simplify the calibration process.
The recommended power-up sequence for the ADS5463IPFPR is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps to ensure that the device powers up correctly and minimizes the risk of latch-up or other issues.
