External clock source characteristics
High-speed external user clock generated from an external source
The characteristics given in Table 19 result from tests performed using an high-speed
external clock source, and under ambient temperature and supply voltage conditions
summarized in Table 8.
Low-speed external user clock generated from an external source
The characteristics given in Table 20 result from tests performed using an low-speed
external clock source, and under ambient temperature and supply voltage conditions
summarized in Table 8.
