The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization of the device.
To optimize performance in a noisy environment, ensure proper grounding and shielding of the device, use a low-pass filter to remove high-frequency noise, and consider using a ferrite bead or common-mode choke to reduce electromagnetic interference.
The maximum clock frequency that can be used with the CS4344-DZZ is 192 kHz. Exceeding this frequency may result in reduced performance or device malfunction.
To configure the CS4344-DZZ for master clock mode, connect the MCLK pin to a clock source, set the MCLKDIV pin to the desired clock division ratio, and ensure that the BCLK pin is not connected to a clock source.
The recommended layout and routing for the CS4344-DZZ involves keeping analog and digital signals separate, using a ground plane to reduce noise, and minimizing trace lengths and impedance mismatches.
