CS4391A-KZZ Frequently Asked Questions (FAQs)
-
The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures proper device operation and prevents damage.
-
To configure the CS4391A-KZZ for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the specified range (256 fs to 512 fs). Also, set the BCK pin as the bit clock output, and the LRCK pin as the frame clock output.
-
The analog power supply (AVDD) powers the analog circuitry, including the ADC and DAC, while the digital power supply (DVDD) powers the digital circuitry, including the serial interface and control logic. Separating the power supplies helps to reduce noise and improve overall device performance.
-
To ensure proper grounding, connect the AGND pin to the analog ground plane, and the DGND pin to the digital ground plane. Keep the analog and digital ground planes separate to minimize noise coupling and ensure optimal device performance.
-
The maximum allowed capacitance for the analog and digital power supply pins (AVDD and DVDD) is 10 μF. Exceeding this value may cause power supply instability and affect device performance.
