"Z" High impedance

Notes : • Phase error detection range : −2π to +2π

• Spikes on Do pulse during locking state are output to prevent dead zone

• LD output becomes “L” level when phase error is tWU or more.

• LD output becomes “H” level when phase error is tWL or less and continues to be so for three

cycles or more.

• tWU and tWL depend on OSCin input frequency.

tWU ≥ 8/fOSC [s] : i.e. tWU ≥ 625 ns, fOSC = 12.8 MHz

tWL ≤ 16/fOSC [s] : i.e. tWL ≤ 1250 ns, fOSC = 12.8 MHz
