Part Number: TIDM-TM4C129POEAUDIO
TI support and fellow design engineers,
We have a legacy design where we have digitized PCM audio on a Motorola 68360 microprocessor communicates to a Xilinx FPGA, which in terms drive a PCM Codec (TLV320IC1110PBS). The codec hooks up to analog circuitry to drive a voice radio PTT interface (600 ohms).
In effort modernize the chain as well as passing the digitized audio in a given distance (100 feet), we would like to store the PCM audio in a 32 bit processor internal flash, network into TM4C129x and be a public announcer (PA) . We are interested in the reference design with TIDM-TM4C129POEAudio and leverage its capability to decode packet audio and translate in analog audio frequency signal. We imagine using a single end of the reference design, with our processor being able to mimic the transmitted data frame with the audio from what would have been another TM4C129x encoding the Mic in.
My main question is with respect to the compressed audio stream on the network. Is there a compatible version of OPUS codec freely available so that my source processor can communicate to the TM4C129 on the network?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
