DEVICE LITERATURE NO. TLV320AIC12 SLWS115 TLV320AIC13 SLWS139 TLV320AIC14 SLWS140 TLV320AIC15 SLWS141 TLV320AIC20 SLAS363 TLV320AIC21 SLAS365 TLV320AIC24 SLAS366 TLV320AIC25 SLAS367 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 productвЂ™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 productвЂ™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 …

Interfacing the TLV320AIC12/13/14/15 Codec to the TMS320C5402? DSP
PDF, 156 Kb, File published: Oct 24, 2002
This application report presents the process of interfacing of the TLV320AIC12/13/14/15 voice-band codec with the TMS320C5402? DSP. It presents the hardware configuration and the software driver for a two-device cascade (single master and single slave) configuration mode. The design can be considered as an application example, a test tool, or a startup platform for developing and using the codec
