Power supply

• Crystal resonator connection

(4.5/7.2 MHz)

• FMIN is selected when the serial data input DVS bit is

set to 1.

• The input frequency range is from 10 to 130 MHz.

• The input signal passes through the internal divide-by-

two prescaler and is input to the swallow counter.

• The divisor can be in the range 272 to 65535. However,

since the signal has passed through the divide-by-two

prescaler, the actual divisor is twice the set value.

• AMIN is selected when the serial data input DVS bit is

set to 0.

• When the serial data input SNS bit is set to 1:

— The input frequency range is 2 to 40 MHz.

— The signal is directly input to the swallow counter.

— The divisor can be in the range 272 to 65535, and

the divisor used will be the value set.

• When the serial data input SNS bit is set to 0:

— The input frequency range is 0.5 to 10 MHz.

— The signal is directly input to a 12-bit programmable

divider.

— The divisor can be in the range 4 to 4095, and the

divisor used will be the value set.

Set this pin high when inputting (DI) or outputting (DO)

serial data.

• Used as the synchronization clock when inputting (DI) or

outputting (DO) serial data.

• Inputs serial data transferred from the controller to the

LC72133.

• Outputs serial data transferred from the LC72133 to the

controller.

The content of the output data is determined by the

serial data DOC0 to DOC2.

• The LC72133 power supply pin (VDD = 2.7 to 3.6 V)

• The power on reset circuit operates when power is first

applied.
