Notes:
7. The
t(φ) reference feedback input delay is guaranteed for a maximum 4:1 input edge ratio between the two signals as long as tSR(I) is maintained.
8. Parameters guaranteed by design and characterization, not 100% tested in production.
9. Includes typical board trace capacitance of 6–7pF each XIN, XOUT.
