I am using an TI PCM1804 to convert my audio signal.
The PCM1804 is configured as follows: Master Mode, with 12.288MHz input clock Sample rate: 48kHz
The testsignal is a 440Hz sine with an amplitude of 4.5V_pp. In order to get a balanced signal from the signal generator, I use a circuit which is identical to the one in the PCM1804 evaluation kit: http://www.ti.com/lit/ug/sleu015/sleu015.pdf
After analyzing the ouput, unfortunately there is no 440 Hz sine but a distorted signal. I can post a picture of it in the next post.
Can anybody help with this issue? I have no idea where this comes from. Thanks in advance! audio_horrible
