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.
To configure the PCM3070 for master mode operation, set the M/S bit in the Control Register (CR) to 1, and ensure that the BCK pin is driven by the PCM3070. Additionally, the WS pin should be driven by the PCM3070 or an external clock source.
The maximum clock frequency supported by the PCM3070 is 50 MHz. However, the actual clock frequency used depends on the specific application and the clock source used.
To handle clock jitter and skew, it is recommended to use a high-quality clock source, such as a crystal oscillator, and to ensure that the clock signal is properly terminated and routed. Additionally, the PCM3070 has built-in clock jitter tolerance and can handle clock skew up to 1 ns.
The recommended layout and routing for the PCM3070 involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, it is recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
