1. The Si5321 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 Si5321 device can operate with input clock swings as high as 1500 mV
