Texas Instruments (TI) has recently identified a problem in the product models listed above related to DLL

clock-generation. When a clock-generation mode is used that powers up the delay-locked-loop (DLL), the DLL

may not startup properly when initiated, resulting in the audio master clock not functioning. This results in the

codec in the products not functioning. This issue does not affect applications that do not enable the product’s

DLL.

Since this issue does not affect operation if the DLL is not enabled, customers are recommended to ensure their

system does not enable the product’s DLL. The DLL is enabled anytime the P value in control register #4

(pertaining to clock generation) is NOT set equal to 8. The DLL is used whenever the part is in fine sampling

mode, as described in Section 3.1 of the data manual, so the recommended mode to use is the coarse sampling

mode, which requires P=8.

At present, TI does not have a screening procedure in place to detect product with the DLL issue, but the

company also realizes that many customers do not use the DLL in their systems and will be unaffected by this

issue.

TI is not confident of the operation of the DLL in this product at this time. To ensure customers have been made

aware of this issue, orders for these parts will only be filled upon return of a signed waiver until this issue is

resolved. The company has initiated an investigation to fully understand the root cause of this problem and

determine what appropriate long-term corrective action should be taken. TI recommends that all customers

presently using these parts contact the company immediately, so they can receive updates on this investigation

and plans for its resolution.

We apologize for the inconvenience placed upon customers in ordering this product. However, we wish to

ensure that our customers are aware of the device shortcomings from the specification. We are working in

earnest to remove this waiver requirement.
