Notes: • Phase error detection range: –2π to +2π
• Pulses on Do signal during locked state are output to prevent dead zone.
• LD output becomes low when phase is tWU or more. LD output becomes high 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 > 2/fosc (s) (e. g. tWU > 156.3 ns, fosc = 12.8 MHz)
tWU < 4/fosc (s) (e. g. tWL < 312.5 ns, fosc = 12.8 MHz)
• LD becomes high during the power saving mode (PS = “L”).
