Notes:
1. This delay is a function of voltage and temperature. See Table 2-6 on page 2-5 for deratings
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 for more information.
4. Maximum value obtained for a –2 speed-grade device in worst-case commercial conditions. For specific junction
temperature and voltage supply levels, refer to Table 2-6 on page 2-5 for derating values.
5. 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.
