説明
The 6V49205B is a clock generator specifically designed for the Freescale P1010, P1020, P2020, and P2040 processors. The device uses a low-cost 25MHz 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/83.333MHz 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
