Texas Instruments recommends a 4-layer PCB with a dedicated ground plane, and to keep the analog and digital signals separate. Additionally, use short traces, and avoid crossing analog and digital signals. Refer to the TI application note 'PCB Layout Guidelines for PCM55HP' for more details.
The PCM55HP/1K is a 24-bit device, but it can be configured for 16-bit operation by setting the appropriate bits in the control register. Refer to the datasheet section 'Control Register' and 'Audio Data Format' for more information.
The PCM55HP/1K supports clock frequencies up to 50 MHz. However, the maximum clock frequency may vary depending on the specific application and system requirements. Consult the datasheet section 'Clocking' for more details.
The PCM55HP/1K has a power-down mode that can be controlled through the control register. When in power-down mode, the device consumes minimal power, but the analog and digital circuits are disabled. Ensure that the system is designed to handle the power-down mode, and that the device is properly reset before resuming operation.
The PCM55HP/1K has a maximum junction temperature of 150°C. Ensure good thermal design practices, such as providing adequate heat sinking, using thermal vias, and keeping the device away from heat sources. Consult the datasheet section 'Thermal Information' for more details.
