The recommended power-up sequence is to apply VCC first, followed by VREF, and then the clock signal. This ensures that the internal voltage regulators are powered up correctly and the device is properly initialized.
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 voltage reference for the VREF pin.
The maximum clock frequency that can be used with the PCM1803 is 256 fs (where fs is the sampling frequency). However, it's recommended to use a clock frequency that is at least 10 times the sampling frequency to ensure proper operation.
The PCM1803 outputs data in a 24-bit, MSB-first, two's complement format. The data should be latched on the rising edge of the clock signal, and the output data should be processed according to the specific application requirements.
To minimize noise and ensure proper operation, it's recommended to use a multi-layer PCB with separate analog and digital grounds, and to keep the analog input traces away from the digital output traces. Also, use a low-inductance path for the clock signal and ensure that the power supply decoupling capacitors are placed close to the device.
