For our previous version we used 1.8v (pin37) level, for CMOS output,
now it is changed to 3.3 level .
the routing is a little complex when we changed to 3.3v
is that only thing we need to do.
please review this schematics.
Per the data sheet, if you are using the 3.3V CMOS driver, then provide a separate 3.3V supply with a ferrite bead. This appears to be what your schematic shows. As far as I can tell, that is all you need to do in order to use the 3.3V CMOS driver.
