The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital power supply (VCCIO). This ensures that the internal voltage regulators are powered up correctly.
To optimize the PCB layout, keep the analog and digital power supply traces separate, use a solid ground plane, and place the decoupling capacitors close to the device. Also, ensure that the clock signal traces are short and shielded to minimize noise.
The maximum clock frequency supported by the PCM5102AQPWRQ1 is 216 kHz. However, the recommended clock frequency is 192 kHz for optimal performance.
To configure the PCM5102AQPWRQ1 for Master Clock Mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Also, ensure that the LRCK pin is set to the desired left-right clock frequency.
The recommended operating temperature range for the PCM5102AQPWRQ1 is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance.
