tw(CIL)

CLKIN low pulse duration, tc(CI) = 50 ns (see Note 4)

tw(CIH)

CLKIN high pulse duration, tc(CI) = 50 ns (see Note 4)

tsu(S)

SYNC setup time before CLKIN low

Q – 10

th(S)

SYNC hold time from CLKIN low

† Value derived from characterization data and not tested.

NOTES: 3. Q = 1/4tc(C).

4. CLKIN duty cycle [tr(CI) + tw(CIH)] /tc(CI) must be within 40-60%.
