DO Output Data (Serial Data Output) Structure
3. OUT mode
DO Output Data
No.
Control block/data
Description
Related data
IF counter control data
IFS
IFIN pin input sensitivity control data. This data should be set to 1 in normal operation.
Setting this data to 0 switches the LC72122V to a reduced input sensitivity mode in which
the sensitivity is reduced by 10 to 30 mVrms.

Sub-charge pump control
data
SUBC
This data controls the sub-charge pump (PDS) which is provided for fast locking.
By setting SUBC to 1, applications can set the sub-charge pump circuit to the operating
state and increase the speed of frequency looking.

All three bits must be set to 0.
All the test data is set to 0 at a power-on reset.

Description
Related data
I/O port data
I2, I1
Data latched from the states of the I/O ports, pins IO1 and IO2.
This data reflects the pin states, regardless of whether they are in input or output mode.
The data is latched when OUT mode is selected.
I1
←
IO1 pin state
High: 1
I2
←
IO2 pin state
Low: 0
Data latched from the state of the unlock detection circuit
UL
←
0: Unlocked
UL
←
1: Locked or in detection stopped mode
Data latched from the state of the IF counter, which is a 20-bit binary counter.
C19
←
Binary counter MSB
C0
←
Binary counter LSB
PLL unlock data

Note:
*
Data with a value of “0”
**
Note : Although the IC is initialized after power is first applied by the power on reset circuit, applications must also send a full set of data over the CCB bus
immediately after power is first applied to assure safe and stable operation.
