DO
Notes : • Phase error detection range:
•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”).
