24-bit Audio CODEC
The MAX 10 Plus offers high-quality 24-bit audio via the Texas Instruments TLV320AIC3254
audio CODEC (Encoder/Decoder). This chip on MAX 10 Plus supports, line-in, line-out and
microphone-in ports with adjustable sample rate from 8KHz to 192KHz. The connection of the
audio circuitry to the FPGA is shown in
, and the associated pin assignment to the
. More information about the TLV320AIC3254 CODEC is available in
its datasheet, which can be found on the manufacturer’s website, or in the directory
\Datasheet\Audio CODEC of MAX 10 Plus System CD.
