TLV320AIC3204 bandwidth for SDR?

Raymond Mack

I am exploring using the 5535 EVM for low frequency SDR operation. It looks like all the normal setup for the 3204 limits the audio bandwidth to 20 kHz. It is not clear if it is possible to use 192 kHz sampling with Decimation filter A to give bandwidth on the order of 40 kHz. Is it possible? has anyone actually done such an unusual thing?

Thanks.

Hi Raymond,

Decimation Fiter A is intended to be used with 48KHz sampling rate for better performance, resulting in a bandwidth up to 20KHz. However, Filter A can also be used for 96kHz at an AOSR of 64, resulting in a bandwidth up to 40KHz.

Thanks. Long term solution is to use a better ADC, but for now this will get me some more bandwidth...
