Texas Instruments provides a layout guide 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 differential pairs for clock and data lines.
The clock input should be driven differentially, and the clock signal should be terminated with a 100-ohm resistor to match the impedance of the device. Additionally, the clock signal should be filtered to remove high-frequency noise.
The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures that the device is properly initialized and configured.
To optimize performance in a noisy environment, use shielding, filtering, and decoupling to reduce electromagnetic interference (EMI). Additionally, use a low-noise power supply, and consider using a ferrite bead or common-mode choke to filter the clock signal.
The maximum clock frequency is 100 MHz, but it's recommended to use a clock frequency of 50 MHz or less to ensure optimal performance and minimize jitter.
