Hello,
I have used four codec (TLV320AIC24K), with one master device and three slave devices since 2006 year.
Then recently it is occurring the issue that the FS(Frame Sync) signal is out of sync on some boards in low temperature ( 0 ~ -10 degree C).
The cases are the following
1. The width of the master device's FS signal is changed to more than one clock(SCLK reference) sometimes.
2. The position of the master device's FSD signal is continuously moving to another time.
3. Sometimes the SCLK is disappeared.
4. Sometimes the voltage level of the SCLK is changed by approximately 0.5V. (above from 0V and below from 3.3V)
I ask your help for the above issue.
Thanks.
