AD1941 i2c with USBi programmer


Just wondered if the USBi programmer can supply the clock to the AD1940 / 1 to initialize the chip or if I need to supply an additional external mclk ? I see on the schematic of the USBi there is a 24mhz crystal but it doesn't quite divide into the 48khz or 96khz x FS clock speed I would select on the PLL pins of the IC.

I guess I'll hook another clock from a codec and see if that works. chip not initializing with USBi alone.

just thought someone might know the answer already ? the Eval boards are using the master clocks generated from Codecs it seams.

thanks , ben
