Notes:
15. Period, jitter, offset, and skew measured on rising edge at 1.25 for 2.5V clocks and at 1.5V for 3.3V clocks.
16. T
HIGH
is measured at 2.0V for 2.5V outputs, 2.4V for 3.3V outputs.
17. T
LOW
is measured at 0.4V for all outputs.
18. T
and T
FALL
are measured as a transition through the threshold region V
ol
= 0.4V and V
oh
= 2.0V (1 mA) JEDEC specification for 2.5V outputs and V
OL
= 0.4V and V
= 2.4V for 3.3V outputs.
19. The time specified is measured from when V
DDQ3
achieves its nominal operating level (typical condition V
DDQ3
= 3.3V) until the frequency output is stable
and operating within specification.
Output Enable Delay (All outputs)
Output Disable Delay (All outputs)
All Clock Stabilization from Power-Up
