PCM4222PFB Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures that the internal voltage regulators are powered up correctly.
-
To optimize the analog input impedance, use a series resistor (Rs) and a shunt capacitor (Cs) to match the impedance of the analog input signal to the PCM4222PFB's input impedance. The recommended values are Rs = 220 ohms and Cs = 10 nF.
-
The PCM4222PFB supports clock frequencies up to 128 kHz, but the maximum frequency depends on the specific application and the quality of the clock signal. It's recommended to use a clock frequency of 64 kHz or lower for most applications.
-
The PCM4222PFB outputs data in a 24-bit, MSB-first, two's complement format. The digital output data can be configured to be either I2S or DSP format, depending on the application requirements.
-
To minimize noise and ensure proper operation, it's recommended to follow a star-grounding layout, keep analog and digital signals separate, and use a solid ground plane. Additionally, use short, direct traces for the analog input signals and avoid crossing digital signals over analog signals.
