Texas Instruments provides a recommended layout and routing guide in the ADS4246IRGC25EVM user's guide, which includes guidelines for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
The ADS4246IRGC25 datasheet provides general guidelines for analog input stage design, but optimization requires consideration of specific application requirements, such as input signal amplitude, frequency, and impedance. TI's Analog Engineer's Pocket Reference and the ADS4246IRGC25EVM user's guide provide additional guidance on input stage design and optimization.
While the datasheet specifies a maximum clock frequency of 65 MSPS, the actual maximum clock frequency may be limited by the specific application, PCB layout, and clock source quality. TI recommends using a high-quality clock source and following the clocking guidelines in the datasheet to ensure optimal performance.
TI recommends using a common clock source and frame sync signal to synchronize multiple ADS4246IRGC25 devices. The datasheet provides guidelines for frame sync and data alignment, and the ADS4246IRGC25EVM user's guide provides additional examples and recommendations for multi-device synchronization.
The datasheet provides a recommended power-up and power-down sequence to ensure proper device operation and prevent damage. The sequence involves powering up the analog supply (AVDD) before the digital supply (DVDD), and powering down the digital supply before the analog supply.
