Note: The power consumption of additional circuitry equals about 1.5 mW.
Table 12-20 lists oscillators that can be used with the I210. Please note that no particular oscillator is
recommended):
12.4.1 Oscillator Placement and Layout Recommendations
Oscillator clock sources should not be placed near I/O ports or board edges. Radiation from these
devices can be coupled into the I/O ports and radiate beyond the system chassis. Oscillators should
also be kept away from the Ethernet magnetics module to prevent interference.
