If USB host function is used, it is recommended that a very low PPM crystal (
≤
50 ppm) be used for the
12- or 13-MHz oscillator circuit. If the USB host function is not used, then a crystal of
≤
180 ppm is
recommended. When selecting a crystal, the system design must take into account the temperature and aging
characteristics of a crystal versus the user environment and expected lifetime of the system.
Table 54 shows the switching characteristics of the base oscillator.

5.6.3 Internal Clock Speed Limitations
Table 55 provides a summary of the maximum frequencies that each clock domain may be configured to run
on the OMAP5910 device

All clock domains must be derived from the same DPLL1 frequency setting; therefore, the following conditions
must be satisfied where ‘m’, ‘n’, and ‘o’ are each equal to either 1, 2, 4, or 8:
MPU frequency = (DPLL1 clock frequency) / m
DSP frequency = (DPLL1 clock frequency) / n
TC frequency = (DPLL1 clock frequency) / o
For example, the following configuration is valid:
MPU/DSP/TC = 150 MHz/150 MHz/75 MHz, where m = n = 1 and o = 2
