A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply and decouple the power pins with 10uF and 100nF capacitors.
Use a clock source with a low jitter and a frequency of 12.288 MHz or 24.576 MHz. Ensure the clock signal has a 50% duty cycle and an amplitude of 1.8V to 3.3V. Use a series resistor (e.g., 22 ohms) to terminate the clock signal.
Power up the device in the following sequence: 1) Apply analog power (AVDD), 2) Apply digital power (DVDD), 3) Apply clock signal, and 4) Apply digital inputs. Ensure a minimum delay of 10ms between each step.
Use a heat sink with a thermal resistance of 10°C/W or lower. Ensure good airflow around the device. Keep the ambient temperature below 85°C and avoid exposing the device to direct sunlight or high humidity.
Use a 5th-order Butterworth filter with a cutoff frequency of 20 kHz to 40 kHz. Adjust the filter coefficients based on the specific application requirements.
