Notes:
5. All parameters are specified with loaded outputs.
6. When the device is configured as a non-PLL fanout buffer (PLL Power-down enabled), the reference frequency can be lower than 10MHz. With auto power-down
disabled and PLL power-down enabled, the reference frequency can be as low as DC level.
7. When the device is configured as a non-PLL fanout buffer (PLL Power-down enabled), the output frequency can be lower than 10MHz. With auto power-down
disabled and PLL power-down enabled, the output frequency can be as low as DC level.
8. Guaranteed by statistical correlation. Tested initially and after any design or process changes that may affect these parameters.
9. TTB is the window between the earliest and the latest output clocks with respect to the input reference clock across variations in output frequency, supply voltage,
operating temperature, input clock edge rate, and process. The measurements are taken with the AC test load specified and include output-output skew,
cycle-cycle jitter, and dynamic phase error.TTB will be equal to or smaller than the maximum specified value at a given frequency.
10.Same frequency, 15pF load, high drive.
11. Same frequency, 15pF load, low drive.
