NOTES:

1. SRC clock outputs run only at 100MHz or 200MHz. Specs for 133.33 and 166.66 do not apply to SRC clock pair.

2. This parameter is guaranteed by design, but not 100% production tested.

3. All long term accuracy and clock period specifications are guaranteed with the assumption that the REF output is at 14.31818MHz.
