Specifications

Absolute Maximum Ratings at Ta = 25°C, VSS= 0 V

Allowable Operating Ranges at Ta = –40 to +85°C, VSS= 0 V

Note: * Recommended crystal oscillator CI values:

CI ≤ 120Ω (For a 4.5 MHz crystal)
CI ≤ 70Ω (For a 7.2 MHz crystal)
However, since the oscillator circuit characteristics depend on the printed circuit board and component values actually used, we recommend
requesting a circuit evaluation from the manufacturer of the crystal used.

<Sample Ocsillator Circuit>
Crystal oscillator: HC-49/U (manufactured by Kinseki, Ltd.), CL = 12 pF
C1 = C2 = 15 pF
The circuit constants for the crystal oscillator circuit depend on the crystal used, the printed circuit board pattern, and other items. Therefore we
recommend consulting with the manufacturer of the crystal for evaluation and reliability.

Power supply

• Crystal resonator connection
(4.5/7.2 MHz)

• Serial data input: FMIN is selected when DVS is set to 1.

• The input frequency range is from 10 to 160 MHz.

• The signal is passed through a built-in divide-by-two
prescaler and then supplied to the swallow counter.

• Although the range of divisor settings is from 272 to
65,535, the actual divisor is twice the setting since there
is also a built-in divide-by-two prescaler.

• Serial data input: AMIN is selected when DVS is set to 0.

• Serial data input: When SNS is set to 1:
— The input frequency range is from 2 to 40 MHz.
— The signal is supplied directly to the swallow counter.
— The range of divisor settings is from 272 to 65,535

and the actual divisor will be the value set.

• Serial data input: When SNS is set to 0:
— The input frequency range is from 0.5 to 10 MHz.
— The signal is supplied directly to a 12-bit

programmable divider.

— The range of divisor settings is from 4 to 4,095 and

the actual divisor will be the value set.

• Must be set high when serial data is input to the
LC72130 (DI), or when serial data is output (DO).

• Used as the synchronization clock when serial data is
input to the LC72130 (DI), or when serial data is output
(DO).

• Inputs serial data sent from the controller to the
LC72130.

• Outputs serial data sent from the LC72130 to the
controller.
The content of the output data is determined by the
serial data DOC0 to DOC2.

• The LC72130 power supply (V

DD

= 4.5 to 5.5 V)

• The power on reset circuit operates when power is first
applied.

IF counter

• The LC72130 ground —

• Dedicated output pins

• The output states are determined by BO1 to BO5 in the
serial data.
Data: 0 = open, 1 = low

• These pins go to the open state after the power on reset.

• An 8 Hz time base signal can be output from BO1 when
TBC in the serial data is set to 1.

• Note that the ON impedance of the BO1 pin is higher
than that of the other pins (BO2 to BO5).

• Pins used for both input and output

• The input or output state is determined by bits IOC1 and
IOC2 in the serial data.
Data: 0 = input port, 1 = output port

• When specified for use as an input port:
The input state is transmitted to the controller through
the DO pin.
Input state: Low

→ data value = 0

High → data value = 1

• When specified for use as an output port:
The output state is determined by bits IO1 and IO2 in the
serial data.
Data: 0 = open, 1 = low

• These pins go to the input port state after the power ON
reset.

• PLL charge pump output
When the frequency generated by dividing the local
oscillator frequency by N is higher than the reference
frequency, a high level will be output from the PD pin.
Similarly, when that frequency is lower, a low level will
be output. The PD pin goes to the high impedance state
when the frequencies agree.

• The MOS transistor used for the PLL active low-pass
filter.

• The input frequency range is from 0.4 to 12 MHz.

• The signal is supplied directly to the IF counter.

• The result from the IF counter MSB is output through the
DO pin.

• There are four measurement periods: 4, 8, 32, or 64 ms.
