Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using impedance-controlled traces.
The optimal filtering depends on the specific application and noise environment. TI recommends using a combination of passive and active filtering to achieve the desired signal-to-noise ratio. The datasheet provides some general guidelines, but simulation tools like SPICE or MATLAB can be used to optimize the filter design.
The maximum clock frequency is 250 MSPS, but it's recommended to check the device's performance at the desired clock frequency to ensure it meets the required specifications. Additionally, the clock frequency should be chosen based on the specific application's requirements, taking into account factors like power consumption and noise sensitivity.
The ADS62P48IRGCR has an internal calibration mechanism, but it's recommended to perform an external calibration using a known input signal to ensure optimal performance. The datasheet provides guidelines for calibration, and TI also offers calibration software tools to simplify the process.
A combination of bulk capacitors (e.g., 10uF) and bypass capacitors (e.g., 100nF) should be used to decouple the power supply. The capacitors should be placed as close as possible to the device's power pins, and the layout should be designed to minimize inductance and resistance.
