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. Maximum value obtained for a STD speed grade device in Worst-Case Commercial conditions. For specific junction
5. Tracking jitter is defined as the variation in clock edge position of PLL outputs with reference to PLL input clock edge.
Tracking jitter does not measure the variation in PLL output period, which is covered by the period jitter parameter.
6. VCO output jitter is calculated as a percentage of the VCO frequency. The jitter (in ps) can be calculated by multiplying
the VCO period by the % jitter. The VCO jitter (in ps) applies to CCC_OUT, regardless of the output divider settings. For
example, if the jitter on VCO is 300 ps, the jitter on CCC_OUT is also 300 ps, no matter what the settings are for the
output divider.
7. Measurements done with LVTTL 3.3 V 8 mA I/O drive strength and high slew rate. VCC/VCCPLL = 1.425 V,
VCCI = 3.3 V, VQ/PQ/TQ type of packages, 20 pF load.
8. SSOs are outputs that are synchronous to a single clock domain and have their clock-to-out times within ±200 ps of
each other. Switching I/Os are placed outside of the PLL bank. Refer to the "Simultaneously Switching Outputs (SSOs) and
.
9. The AGLN010, AGLN015, and AGLN020 devices do not support PLLs.
