FMIN is selected when DVS in the serial data input is set to 1.
The input frequency range is 10 to 180 MHz.
The signal is directly transmitted to the swallow counter.
The divisor can be set to a value in the range 272 to 65,535.

signal input
AMIN is selected when DVS in the serial data input is set to 0.
When SNS in the serial data input is set to 1:
—The input frequency range is 2 to 40 MHz.
—The signal is directly transmitted to the swallow counter.
—The divisor can be set to a value in the range 272 to 65,535.
When SNS in the serial data input is set to 0:
—The input frequency range is 0.5 to 10 MHz.
—The signal is directly transmitted to the 12-bit programmable divider.
—The divisor can be set to a value in the range 5 to 4,095.

Connections to the internal n-channel MOS transistor provided to
implement an active low-pass filter for the PLL.
A high-speed locking circuit can be implemented by using these pins in
conjunction with the built-in sub-charge pump.
See the item describing the structure of the charge pump for details.

Input/output shared-function pins
In output mode, the circuits are open-drain outputs.
The I/O direction is determined by I/O-1 to I/O-3 in the serial data.
When the data is 0: input port
When 1: output port
When specified for use as input ports
The input pin states are transmitted from the DO pin to the controller
Input state = low : Data = 0
Input state = high : Data = 1
When specified for use as output ports
The output states are determined by OUT1 to OUT3 in the serial data.
Data = 0 : low
Data = 1 : open
These pins are set to function as input ports by the power-on reset.
