TLV320AIC3254: Purepath Studio GDE - I2S 6 channel input in TDM mode

Part Number: TLV320AIC3254

Audio data flows between the host processor and the TLV320AIC3254 on the digital audio data serial interface,
or audio bus. This very flexible bus includes left or right-justified data options, support for I2S or PCM protocols,
programmable data length options, a TDM mode for multichannel operation, very flexible master-slave
configurability for each bus clock line, and the ability to communicate with multiple devices within a system
directly.

Hi.

I'm trying to use the 3254 GDE to configure the I2S input for 6 channel TDM.

How do I proceed in the GUI? The I2S input icon only max at 2 channel.

I'm using ver 5.95 build 1 14746

  • Hi Jason,

    Two is the maximum number of channels that the I2S input can receive on AIC3254. Even if there are more than two channels in the bus, the device can only receive two channels. There offset parameter determines the slot of the channel to be received by the device.

    I would recommend the AIC3262 device for this use case. AIC3262 supports up to 8 input channels on the primary ASI.

    Best Regards.

  • Thank you.

    Managed to use AIC3262 with 3 I2S pair.
