Notes:
2. TJ = 25°C, VCC = 1.5 V
3. When the CCC/PLL core is generated by Microsemi core generator software, not all delay values of the specified delay
increments are available. Refer to the Libero SoC Online Help associated with the core for more information.
4. The AGL030 device does not support a PLL.
5. Maximum value obtained for a Std. speed grade device in Worst-Case Commercial Conditions. For specific junction
6. Tracking jitter is defined as the variation in clock edge position of PLL outputs with reference to the PLL input clock edge.
Tracking jitter does not measure the variation in PLL output period, which is covered by the period jitter parameter.
7. Measurements done with LVTTL 3.3 V, 8 mA I/O drive strength, and high slew Rate. VCC/VCCPLL = 1.14 V, VQ/PQ/TQ type of
packages, 20 pF load.
8. Simultaneously Switching Outputs (SSOs) are outputs that are synchronous to a single clock domain and have clock-to-out
times that are within ±200 ps of each other. Switching I/Os are placed outside of the PLL bank. Refer to the "Simultaneously
