Xfin
I
Prescaler complementary input, and should be grounded via a
capacitor.
8

fin
I
Prescaler input.
Connection with an external VCO should be done with AC coupling.

Clock
I
Clock input for the 19-bit shift register.
Data is shifted into the shift register on the rising edge of the clock.
(Open is prohibited.)
10
9
Data
I
Serial data input using binary code.
The last bit of the data is a control bit.
Control bit = ”H” ; Data is transmitted to the programmable
reference
counter.
Control bit = ”L” ;
Data is transmitted to the programmable
counter.
(Open is prohibited.)
11
10
LE
I
Load enable signal input
When LE is high, the data in the shift register is transferred to a
latch, according to the control bit in the serial data.
(Open is prohibited.)
12
11
PS
I
Power saving mode control. This pin must be set at ”L” at Power-
ON.
(Open is prohibited.)
PS = ”H” ; Normal mode
PS = ”L” ; Power saving mode
13
12
ZC
I
Forced high-impedance control for the charge pump (with internal
pull up resistor.)
ZC = ”H” ; Normal Do output.
ZC = ”L” ; Do becomes high impedance.
14
13
LD/fout
O
Lock detect signal output(LD)/phase comparator monitoring
output (fout).
The output signal is selected by LDS bit in the serial data.
LDS = ”H” ; outputs fout (fr/fp monitoring output)
LDS = ”L” ; outputs LD (”H” at locking, ”L” at unlocking.)
