(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.

To ensure proper start up, follow one of the following steps when powering up the SLK2721 device.
1. Keep ENABLE (pin 44) low until power supplies and reference clock have become stable.
2. Drive ENABLE (pin 44) low for at least 30 ns after power supplies and reference clock have become
stable.
