Open

• Open selected with power ON reset

* IF counter measurement end check

(1) DO pin open automatically when end-UC is set and the IF counter starts (CTE = 0

→1).

(2) DO pin becomes low, enabling check of the counter end when the IF counter measurement is

over.

(3) DO pin open with serial data input/output (CE pin : Hi)

Note)DO pin open regardless of the DO pin control data (DOC0 to 2) during data input period (IN1

and IN2 modes CE-Hi period).

The DO pin state allows output of the content of internal DO serial data in synchronization with

CL regardless of the DO pin control data (DOC0 to 2) during data input period (OUT mode CE :

Hi period).

UL0, UL1

• Data to select the phase error (φE) detection width to determine if PLL is locked. Unlock is determined

when the phase error exceeding the detection width occurs.

Normal operation

Forced Low

When the VCO control voltage (Vtune) develops dead lock because of stop of oscillation of VCO at

0V, set the charge pump output to LOW and Vtune to VCC to escape the dead lock. (Dead lock

clear circuit)

IFS

• Normally, set data = 1. Setting the data = 0 causes worsening of the input sensitivity, resulting in decrease

of the sensitivity by about 10 to 30mVrms.
