LD

Phase locked state detection output.

This output goes to the on state when the PLL

locked state is detected.

This is an open-collector output.

VREG

PD

Phase comparator output (PLL output).

This pin output the phase error as a pulse signal

with varying duty.The output current increases as

the duty becomes smaller.
