The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures proper initialization of the device.
To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog power supply. Also, ensure that the clock signal traces are short and shielded to minimize jitter.
The maximum clock frequency that can be used with the PCM5141PW is 256 fs (fs = sample frequency). For example, for a sample frequency of 48 kHz, the maximum clock frequency is 12.288 MHz.
To configure the PCM5141PW for Master Clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the bit clock frequency (typically 64 fs). Also, ensure that the LRCK pin is set to the frame clock frequency (typically fs).
The recommended termination for the digital output pins of the PCM5141PW is a 50-ohm resistor to ground, to ensure proper signal integrity and minimize reflections.
