5.3.4
The MPC8572EAMC has four SGMII Gigabit Ethernet interfaces. In order to minimize on PCB floor
space, a single 25-MHz crystal is fed into an IDT ICS524, low skew 1:4 clock buffer. This is illustrated in
Figure
5.3.5
A single 25-MHz crystal oscillator and 22 Ω series resistor is used to provide the input clock to the Marvell
88E3018 PHY, shown in
5.3.6
The AdvancedMC Module Management Controller uses a ColdFire MCF5213 to provide card
management control requires a 9.8304-MHz clock source as shown in
