Thank you so much Diego. I figured as much on the clock frequencies for the 1401. The PCM4222 documentation is pretty vague on using several chips in a multi-channel implementation that doesn't use an I2 buss. I was wondering how critical the use of BCLK and LRCLK are to the operation of the PCM4222 in a multi-channel system. Right now I have the pins for each of these connected in a buss trace so all 4 PCM4222 have their BCLK and LRCLK pins connected together respectively. I have jumpers to pull the Slave/Master pins LO or HIGH on each PCM4222 . I have tried multiple combinations of having the chips in either slave or master mode with no avail. Do these pins really need to be connected to anything? I thought I would ask before I begin severing traces...
