Other Parts Discussed in Thread: TLV320AIC3120
Hi,
Currently I am having TLV320AIC3120EVM-U evaluation kit, in which I wanted to configure the clocks and audio interface as per custom board requirements and play the audio file from PC and listen through headphone Jack (J4).
In my custom board, codec is going to be interfaced to Vocoder(AMBE-4020 Full-Duplex BGA), with the following requirements :
Sampling frequency (WCLK) : 8 Khz
I2S format : DSP
CODEC CLK/ PLL:
Please refer to the TLV320AIC31xx sheet from the attached excel for the clock parameters. According to the forum, https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1125513/tlv320aic3100-i2c-configuration-of-tlv320aic3100-for-16-bit-16-khz-and-mono-audio/4195941?tisearch=e2e-sitesearch&keymatch=TLV320AIC3100#4195941, it says that the EVM is programmed only with 44.1KHz Fs. So is there any other possible way to configure the clock parameters as required apart from the solution suggested in the above forum, as currently I am not interfacing the evaluation board with any of the external microcontroller/ processor.
AUDIO INTERFACE:
I wanted to configure EVM to “DSP” format and word length to “16 bits”. When configured the codec interface with these parameters by keeping the clock configurations default and then played an audio file from PC, observed that audio was too noisy and after some time the EVM stopped responding i.e, lights were glown off.
So please suggest a solution where I can configure as per my requirements, play an audio file and listen through headphone jack (J4).
Thanks in Advance.
