Setting is for worst case. Freescale’s EMI interface uses less powerful drivers than those typically used in mDDR devices. A
possible transmission-line effect on the PC board must be suppressed by minimizing the trace length combined with
Freescale’s slower edge-rate drivers. The i.MX28 provides up to 16 mA programmable drive strength. However, the 16-mA
mode is an experimental mode. With the 16-mA mode, the EMI function may be impaired by Simultaneous Switching Output
(SSO) noise. In general, the stronger the driver mode, the noisier the on-chip power supply. Freescale recommends not using
a stronger driver mode than is required. Because on-chip power and ground noise is proportional to the inductance of its return
path, users should make their best effort to reduce inductance between the EMI power and ground balls and the PC board
power and ground planes.
