Fall Time Tf - 2.5 - nsec Period of transition time required for the output reach 20% from 80% of VDD. Output Lock-Time Tlock - - 1 msec *3 Note) The output frequency is determined by the arithmetic (frequency division) expression of a frequency input to XTALIN. If the input frequency is set to 27.0000MHz, the output frequency will be as listed above.
