(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 (V
DD
= 2.7 to 3.6 V)
The power on reset circuit operates when power is first
applied.
