TAC5111: TU-T G.711 and G.712 PCM codecs?

Daisuke Nomura

Part Number: TAC5111
Other Parts Discussed in Thread: TLV320AIC1110,

Tool/software:

Is it possible to introduce a case where TAC511 was used to realize ITU-T G.711 and G.712 PCM codecs?

    Hi Nomura-san,

    We can't fully support those standards inside the codec. You could get close with 8kHz sampling and 16 bit depth, but 8 bit depth is not available. Some external processing would be needed.

    Thank you for your explanation. Let me continue for a bit. If you know the following, could you please let me know? The TAC5111 is introduced on the website of the TLV320AIC1110, which has an ITU-T G.711 code and a filter that takes G.712 into consideration, as "There is a new version of this product." Therefore, it appears that your company's ITU-T G.711/G.712-compliant PCM_CODEC is fading out. The G.711/G.712 standard for landline telephones is an ITU-T international standard, and landline telephones were once used in countries around the world, but should we think that they are no longer used (or are close to being used) including in developing countries?

    Hi Nomura-san,

    We have not targeted telephone applications directly by including the mu and a law encoding necessary for these standards. We are assuming these encoders are happening at some host side before being transmitted over long distance. I am not very sure about the relevance of these standards now. The AIC1110 is still active and available if you need these encodings, but they are not directly included in our newer products.
