A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power plane to minimize noise and crosstalk.
Use a heat sink or thermal pad to dissipate heat, and ensure good airflow around the device. Also, consider using a thermal interface material to improve heat transfer.
The input clock signal should be a differential signal with a frequency range of 25 MHz to 150 MHz, and an amplitude of 200 mV to 1 V peak-to-peak.
Use a logic analyzer or oscilloscope to monitor the input and output signals, and check the device's configuration and programming. Also, verify that the power supply and clock signals are within the recommended specifications.
Yes, use shielding and filtering to minimize electromagnetic interference (EMI). Also, ensure that the PCB layout and component placement minimize electromagnetic radiation.
