The recommended power-on sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
To optimize the analog input circuitry, use a low-pass filter to remove high-frequency noise, and ensure that the input impedance is matched to the source impedance. Also, use a high-quality, low-noise analog power supply.
The maximum clock frequency that can be used with the PCM1807PWR is 256 fs (where fs is the sampling frequency). For example, at a sampling frequency of 44.1 kHz, the maximum clock frequency is approximately 11.2896 MHz.
The PCM1807PWR outputs data in a 24-bit, MSB-first, left-justified format. The data is output on the DOUT pin, and the clock signal is output on the BCK pin. The data is valid on the rising edge of the BCK signal.
To minimize noise and ensure optimal performance, keep the analog and digital circuits separate, use a solid ground plane, and route the analog and digital signals on separate layers. Also, use a low-inductance path for the power supply lines.
