The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
The analog input impedance can be optimized by using a buffer amplifier with a low output impedance and a high input impedance. This ensures maximum signal transfer and minimizes signal loss.
The maximum clock frequency that can be used with the PCM3001E/2K is 256 fs (fs = 1/sample rate). For example, for a sample rate of 48 kHz, the maximum clock frequency is 12.288 MHz.
Clock jitter can be handled by using a high-quality clock source, such as a crystal oscillator, and by using a clock jitter attenuator circuit. Additionally, the PCM3001E/2K has a built-in clock jitter tolerance of ±10%.
The recommended layout and routing for the PCM3001E/2K involves keeping the analog and digital signals separate, using a ground plane, and minimizing the length of the clock signal traces. Additionally, the device should be placed close to the analog signal sources and the clock signal source.
