The IDT 6V49205B is a clock generator specifically designed for the Freescale P1010, P1020, P2020 and P2040 processors. The device uses a low-cost 25 MHz crystal as an input and generates 19 high-quality output clocks for use in Freescale-based systems. The 6V49205B produces the following output frequencies: 

1 – 100MHz / 66.66MHz / 80MHz / 83.333 MHz selectable for System CCB
1 – DDR_CLK; selectable 100MHz or 66.66MHz
2 – 12MHz / 24MHz selectable outputs for USB
6 – PCIe differential low power push-pull pairs; selectable 100MHz or 125MHz
6 – REF, 25MHz
2 – 2.048MHz for E1
1 – 125MHz for Gigabit
