The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization and prevents damage to the device.
To configure the CS42526K-CQZ for master clock mode, set the MCLK pin to the desired clock frequency, and ensure that the BCLK pin is tied to the MCLK pin. Additionally, set the I2S format to 'Master' mode through the I2C interface.
The maximum allowed capacitance for the analog input filters is 10nF. Exceeding this value may affect the device's performance and stability.
To optimize the CS42526K-CQZ for low power consumption, use the power-down modes (PD1 and PD2) when not in use, reduce the clock frequency, and adjust the analog input bias current. Additionally, consider using the device's built-in low-power modes, such as the 'Low Power' mode.
The recommended layout and routing for the CS42526K-CQZ involves keeping the analog and digital signals separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, ensure that the power supply decoupling capacitors are placed close to the device.
