Hi Team,
customer has one project that is evaluating AIC3262 DIN/DOUT function. Please assist for the customer questions that we can duplicate the situation on the AIC3262 EVM.
Question:
Customer request that AIC3262 need to turn off the IN1/2/3/4/CM switch, and the AIC3262 still can do the ASI1 to ASI2. However, customer found that the DOUT2 will stop output data once turn off all the IN1/2/3/4/CM switch. Please refer to the following procedure for the issue.
Here is the experiment on the AIC3262 EVM.
- Use GDE to place the I2S1 to I2S2
2. Execute Download and Run,then uses Codec Control to control the AIC3262EVM
3. Set the ASI#2 BCLK/WCLK as output in the Digital Settings
4.We can measure the DOUT2 waveform that from ASI1 to ASI2 on the TP30 test point on the AIC3262EVM
5.If we turn off all the input switc, the DOUT2 will stop output data.BCLK2/WCLK2 still has the clock output
Could you please provide your comment why the DOUT2 stop output waveform after turn off all the switch?
Thanks,
SHH
