TLV320AIC3254-Q1: Echo cancellation

Michael Hull37
Prodigy 50 points
Part Number: TLV320AIC3254-Q1
Other Parts Discussed in Thread: TLV320AIC3254, TLV320AIC3254EVM-K, TLV320AIC3253, TLV320AIC3263

Looking at the datasheet for the TLV320AIC3254-Q1 it specifically mentions echo cancellation which is a feature that i'm looking for. The eval module for the TLV320AIC3254-Q1 is the TLV320AIC3254EVM-K. Looking at this EVM in detail I see that it has the TLV320AIC3254 fitted to it. The datasheet for the TLV320AIC3254 has specifically had echo cancellation deleted from it's applications list.

Can I check that the the TLV320AIC3254 is in fact not suitable for echo cancellation and that the TLV320AIC3254-Q1 is suitable ?

    HI, Michael,

    Unfortunately, neither the 'AIC3254 or the 'Q1' version can support Echo cancellation. The datasheet of the automotive part was not updated to the latest format, hence, the mention about the AEC is still there. The miniDSP of these parts is not capable of performing a successful AEC algorithm, so an external DSP will be required for this.

    Hi Luigi

    Thanks for responding so quickly.

    Can I also assume then that the TLV320AIC3253 and TLV320AIC3263 are also not capable of echo cancellation ?

    Regards

    Hi, Michael,

    Correct, unfortunately the miniDSP in our devices doesn't have enough MIPs and memory to perform an effective AEC.
