Notes:⢠Phase error detection range: â2Ï to +2Ï
⢠Pulses on Do output 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 = âLâ).
