Part Details for CS44L11-CZZR by Cirrus Logic

The maximum power consumption of the CS44L11-CZZR is approximately 120 mW, but this can vary depending on the configuration, clock speed, and operating conditions.

To implement Master/Slave mode, you need to configure the device's BCK, WS, and LRCLK pins accordingly. In Master mode, the CS44L11-CZZR generates the clock signals, while in Slave mode, it uses the external clock signals. Refer to the datasheet's section on ' Audio Interface' for detailed pin configurations and timing diagrams.

Cirrus Logic provides a recommended layout and routing guideline in their application note AN221: 'CS44L11-CZZR Layout and Routing Guidelines'. This document provides detailed information on how to separate and route the analog and digital signals to minimize noise and ensure optimal performance.

While the CS44L11-CZZR is designed to operate at 1.8V, it can tolerate a range of voltage supplies from 1.7V to 1.9V. However, it's essential to ensure that the voltage supply is stable and within the recommended range to maintain optimal performance and prevent damage to the device.

To troubleshoot audio quality issues, start by verifying the device's configuration, clock settings, and analog/digital signal routing. Check for any signs of noise, jitter, or distortion. Use audio analysis tools, such as a spectrum analyzer or an oscilloscope, to identify the source of the issue. Consult Cirrus Logic's application notes and documentation for troubleshooting guidelines and recommendations.
