A. For crystal with fundamental frequency from 1 MHz to 24 MHz
B. For input clock frequency higher than 24 MHz, the crystal is not allowed and the oscillator must be used, since the
TL16C752B internal oscillator cell can only support the crystal frequency up to 24 MHz.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Long-term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction of
overall device life. See http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.
