Control block/data
Function
Related data
10
Main charge pump
control data
DLC
Controls the charge pump output (PDa).
* If the circuit deadlocks due to the VCO control voltage (Vtune) being 0 and the VCO being stopped,
applications can get out of the deadlocked state by setting the charge pump output to low and setting
Vtune to VCC. (Deadlock clear circuit)
11
IFS
This data is normally set to 1. Setting this data to 0 sets the circuit to reduced input sensitivity mode, in
which the sensitivity is reduced by about 10 to 30 mV rms.
12
Test data
TEST0 to 2
Test data
TEST0
TEST1
All these bits must be set to 0.
TEST2
All these bits are set to 0 after a power on reset.
13
*
This bit must be set to 0.
14
Sub PLL
programmable
divider data
PS0 to 12
SDVS
Specifies the divisor for the sub PLL programmable divider (FMINb).
This is a binary value in which PS0 is the LSB and PS12 the MSB.
The divisor can be set to a value in the range 272 to 8191. Since the internal divide-by-two prescaler is
used, the actual divisor will be twice the set value.
Sets the sub PLL programmable divider operating state.
*: See the “Structure of the Programmable Divider” section for details.
15
Sub PLL charge
pump control data
SDLC
Forcibly controls the charge pump output (PDb).
* If the circuit deadlocks due to the VCO control voltage (Vtune) being 0 and the VCO being stopped,
applications can get out of the deadlocked state by setting the charge pump output to low and setting
Vtune to VCC. (Deadlock clear circuit)
16
Sub PLL reference
divider data
RS0, RS1
Sub PLL reference frequency (fref) selection data
17
Unlocked state
detection output
switching data
ULa, ULb
The unlocked state information output from the DO pin can be selected to be that for either the main PLL
or the sub PLL.

No unlocked state information is output. The output data, UL is 1.
0
1
Main PLL unlocked state information
1
0
Sub PLL unlocked state information
1
Main PLL plus sub PLL unlocked state information.
(Indicates that either the main or the sub PLL is unlocked.)
