operating MCASP pins at different voltage levels

Christoph Apel

Hi,

we are working on a cost-sensitive application for high volume production. Checking pinmux options, we believe that we can operate MCASP0 pins at different voltage levels, e.g. MCASP0_AHCLKX receives a 1V8 clock on a pin operating in 1V8 domain but MCASP0_FSX, MCASP0_ACLKX and MCASP0_AXR0 outputs run at 3V3. Can you confirm that this will work ? Or at least state that it MAY WELL work ?

thanks a lot and best regards,


Christoph
