Notes:
1. This delay is a function of voltage and temperature. See Table 2-6 on page 2-6 and Table 2-7 on page 2-7
for deratings.
2. TJ = 25°C, VCC = 1.5 V
3. The AGLN010, AGLN015, and AGLN020 devices do not support PLL.
4. 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.
5. Maximum value obtained for a STD speed grade device in Worst-Case Commercial conditions. For specific
junction temperature and voltage supply levels, refer to Table 2-6 on page 2-6 and Table 2-7 on page 2-7
for derating values.
