1. The Si5318 device provides weak 1.5 V internal biasing that enables ac-coupled operation.
2. Clock inputs may be driven differentially or single-endedly. When driven single-endedly, the unused input should be ac
3. Transmission line termination, when required, must be provided externally.
4. Although the Si5318 device can operate with input clock swings as high as 1500 mV
= 3.3 V ±5%, T
