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 PCM1680 for master mode operation, set the M/S pin high and ensure that the BCK pin is driven by the master clock. Additionally, set the WS pin to the desired word length and polarity.
The maximum clock frequency supported by the PCM1680 is 50 MHz. However, the actual clock frequency may be limited by the specific application and system requirements.
To handle clock jitter and skew, use a high-quality clock source and ensure that the clock signal is properly terminated and routed. Additionally, consider using a clock jitter attenuator or a phase-locked loop (PLL) to reduce clock jitter.
The recommended layout and routing for the PCM1680 involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing signal traces near the device. Additionally, ensure that the clock signal is routed close to the device and that the power supply pins are decoupled with capacitors.
