I2S - Header and M.2 E Key

I wanted to ask was there any specific reason that CMOS 1.8 Level i2S lines were not routed directly to M.2 E key. Will there be any potentials issues with routing the i2s3 (CMOS 3.3V) directly to the header. We do not need the option J514 provides as we intend to interface AC328904 Daughter Card that require 3.3V CMOS leveled I2S lines and therefore potentially nullifying the need for voltage translation.


It depends on the device you used. If the device is 3.3V port, then I2S3 can be connected to the device directly.
