VREG

Equivalent circuit

Clock input.

Low: 0 to 1.0 V

16

CLK

High: 2.0 V to VREG

This pin goes to the high level when open.

VREG

Phase locked state detection output

17

17

LD

This output goes to the on state when the PLL locked

state is detected.

This is an open-collector output.

VREG

Phase comparator output (PLL output)

18

PD

This pin output the phase error as a pulse signal with

18

varying duty.The output current increases as the duty

becomes smaller.

EI

Error amplifier in put pin.

300Ω

19

Error amplifier output pin.

20

EO

The output current increases when this output is high.
