Parameter
6. Inputs have pull-up/pull-down resistors that effect input current.
7. Driving series or parallel terminated 50  (or 50  to V
8. Parameters are guaranteed by design and characterization. Not 100% tested in production.
9. Maximum and minimum input reference is limited by VC0 lock range.
10. Outputs loaded with 30 pF each.
11. 50 transmission line terminated into V
12. Tpd is specified for a 50-MHz input reference. Tpd does not include jitter.
