1 Guaranteed by design and characterization, not 100% tested in production.

2 All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz

Preferred drive strengths using CK505 clock sources.

Transmission lines to load do not share series resistors.

Desktop (Zo=50Ω) and mobile (Zo=55Ω) have the same drive strength.
