Electrical Characteristics
3.5.2
This section includes descriptions of the USB PLL electrical specifications and Ethernet PLL electrical
specifications.
3.5.2.1
The i.MX28 integrates a high-frequency USB PLL that provides the 480-MHz clock for the USB and other
system blocks.
Table 32
3.5.2.2
i.MX28 provides a 50-MHz/25-MHz output clock, called the Ethernet PLL output.

Clock output frequency tolerance
This Ethernet output clock tolerance specification is the contribution from the PLL only and assumes a perfect 24 MHz
clock/crystal source with 0 ppm deviation. The 24 MHz crystal frequency tolerance/deviation should be added to this number
for the total Ethernet clock output frequency tolerance.
