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).

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)
(11)
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.
