The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
To configure the PCM2903BDB for master mode operation, set the M/S pin high, and ensure that the BCK pin is driven by the master clock signal. Additionally, configure the I2S format and clock frequency using the I2C interface.
The maximum clock frequency supported by the PCM2903BDB is 50 MHz. However, the actual clock frequency used depends on the specific application and the requirements of the audio codec.
To handle clock jitter and skew, use a high-quality clock source, and ensure that the clock signal is properly terminated and routed. Additionally, use the PCM2903BDB's built-in clock jitter attenuator feature to reduce the effects of clock jitter.
The recommended layout and routing for the PCM2903BDB involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, ensure that the power supply decoupling capacitors are placed close to the device.
