CCS/TLV320AIC3104-Q1: sequence in time for IOVDD = 1.8V

Pei Gong

Part Number: TLV320AIC3104-Q1

Tool/software: Code Composer Studio

Hi,

Audio IC TLV320AIC3104-Q1 provides timing ranges for I2S / LJF / RJF timing and DSP timing only at IOVDD = 1.1V and 3.3V. what is the time sequence if IOVDD = 1.8V？

Thanks for your help!

Hello Pei,

Unfortunately, we don't have any clear information on this. In the mean time, let me check with the design team to try and get some insight.

Aaron

Hello Wu,

I have still not heard from the design team yet.

It is my understanding that the timings provided can be used as a guide for IOVDD = 1.8V. I will continue to push for an answer and will notify you when I receive one. I appreciate your patience.

Regards,

Aaron

Hello Wu,

I heard back from the design team.

The specs for IOVDD = 1.1V and IOVDD = 3.3V are extreme typical values. For the IOVDD = 1.8V case, the number would be in-between the two of these and for a general guide, you can refer to the AIC3204 datasheet for 1.8V and pad a little margin over and above.

Aaron
