TLV320AIC1110: ITU-T G.726 ADPCM (32kbps) CODEC

Part Number: TLV320AIC1110

Hi team,
 
I am working with a customer who is looking for an audio CODEC solution that supports both of the following standards:
  • PCM CODEC Interface: ITU-T G.711 (u-law PCM)
  • ADPCM CODEC Interface: ITU-T G.726 (32kbps)
For the G.711 u-law PCM requirement, I have identified TLV320AIC1110 as a suitable candidate, as it supports 8-bit companded u-law/A-law data format in hardware.
However, I was unable to find a TI device with native hardware support for ITU-T G.726 (32kbps ADPCM). After reviewing the TLV320AIC1110 datasheet (SLAS359), there is no mention of G.726 ADPCM support.
Could you please advise:
  1. Does TI offer any audio CODEC device with native hardware support for ITU-T G.726 (32kbps ADPCM)?
  2. If no hardware solution exists, is there an official TI software/DSP library that implements G.726 ADPCM encoding/decoding (e.g., for TMS320 DSP family)?
  3. Is there a recommended combination of TI devices and software to fulfill both G.711 u-law and G.726 32kbps requirements?
Any guidance or product recommendations would be greatly appreciated.
Thank you in advance for your support.
 
Best regards,
