Cx31993: Datasheet Fix

The CX31993 requires a highly precise 24.000 MHz crystal. Ensure the load capacitors match the crystal manufacturer's specification (typically 12pF to 22pF).

Using the datasheet-recommended 2.2kΩ resistor can cause clipping or failure to detect standard smartphone headsets. Cx31993 Datasheet Fix

Because the CX31993 is a low-cost solution, the implementation (capacitors, shielding, connector quality) varies. If you experience constant disconnections or severe, uncontrollable noise, it is likely a hardware defect in the specific dongle manufacturer's assembly, rather than a failure of the chip itself. The CX31993 requires a highly precise 24
