Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure
to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. Typical values are at 25°C.
3. If crystal is used as input with CL = 16pf. If a clock is used as input, the duty cycle of the 14.318MHz output will be the same as the
input clock.
