A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep analog and digital traces separate, and use a common mode filter to reduce noise.
Use a 4th-order Butterworth filter with a cutoff frequency of 1/3 to 1/2 of the Nyquist frequency to minimize aliasing and maximize signal-to-noise ratio.
Use a low-jitter clock source, and consider using a clock buffer to reduce clock skew. Ensure the clock frequency is within the recommended range of 10-40 MHz.
Use a FIFO or a buffer to handle the high-speed digital output data. Ensure the receiving device can handle the data rate of up to 1.2 Gbps.
Power up the analog supply (AVDD) before the digital supply (DVDD). Ensure the power supplies are stable and within the recommended voltage range.
