The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization of the device.
To optimize power consumption, ensure that the device is operated at the lowest possible clock frequency, use the power-down mode when not in use, and minimize the number of active channels.
The maximum clock frequency that can be used with the PCM3500E/2K is 50 MHz. However, it's recommended to operate the device at a clock frequency of 25 MHz or lower to ensure optimal performance and power consumption.
To handle clock jitter and skew, use a high-quality clock source, ensure that the clock signal is properly terminated, and use a clock buffer or repeater if necessary. Additionally, use the device's built-in clock jitter tolerance feature to compensate for any clock jitter.
The recommended layout and routing for the PCM3500E/2K involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
