The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and that the device is properly initialized.
To optimize the PCB layout, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog signals away from the digital signals. Also, use a low-impedance power supply and decouple the power pins with capacitors.
The maximum clock frequency that can be used with the PCM1754 is 192 kHz. However, the device can also operate at lower clock frequencies, such as 44.1 kHz, 48 kHz, and 96 kHz, depending on the application requirements.
To configure the PCM1754 for Master Clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and configure the device for Master mode by setting the appropriate bits in the control register.
The recommended termination for the digital outputs of the PCM1754 is a 50-ohm resistor in series with a 50-pF capacitor to ground. This provides a matched impedance and helps to reduce electromagnetic interference (EMI).
