Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate to minimize noise and crosstalk. Additionally, it's recommended to use a 10nF capacitor between the analog and digital grounds.
To optimize the performance of the PCM56P-L in a noisy environment, use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke to filter out noise on the analog input lines.
The maximum clock frequency that can be used with the PCM56P-L is 25 MHz. However, it's recommended to use a clock frequency of 16 MHz or lower to ensure reliable operation.
To troubleshoot issues with the PCM56P-L, start by checking the power supply voltage, clock frequency, and analog input signals. Use an oscilloscope to verify the analog input signals and the clock signal. Also, check the digital output signals to ensure they are correct.
The PCM56P-L is designed to operate with a 5V power supply, but it can also operate with a 3.3V power supply with some limitations. However, it's not recommended to use the device with a power supply voltage below 3.3V or above 5.5V.
