frequency synthesizers for electronic tuning. The LC7218,
LC7218M and LC7218JM are optimal for AM/FM tuner
circuits that require high mounting densities.

Function
• These pins latch bits O0 to O6 in the serial data transferred from the controller, invert
that data and output the inverted data in parallel.
• The OUT0 pin can also be used to output an 8 Hz clock time base signal.
(When TB is 1.)
• OUT1 and OUT2 are complementary outputs.
• OUT0, OUT3, OUT4, OUT5 and OUT6 are N-channel open drain outputs that can
handle up to 13 V.
• The values of the IN0 and IN1 input ports can be converted from parallel to serial and
output from the DO output pin.
16 HCTR
Input
General-purpose
counter
Frequency
measurement signal
input pin
• HCTR is selected when SC in the serial input data is set to 1.
• Input frequency range: 10 to 60 MHz (70 mVrms minimum)
• The signal is supplied to a general-purpose 20-bit binary counter after passing through a
divide-by-eight circuit. Therefore, the value of the counter is 1/8 of the frequency actually
input to HCTR.
• When HCTR is selected the LC7218 will function in frequency measurement mode
and the measurement period can be selected to be either 60 or 120 ms. (GT = 0: 60 ms,
1: 120 ms)
• The result of the measurement (the value of the general-purpose counter) can be output
MSB first from the DO output pin.
15 LCTR
Input
General-purpose
counter
Frequency or period
measurement signal
input pin
• LCTR is selected when SC in the serial input data is set to 0.
• When SF in the serial input data is set to 1:
— Frequency measurement mode is selected.
— Input frequency range: 15 to 500 kHz (70 mVrms minimum).
— The signal is supplied directly to the general-purpose counter without passing
through the internal divide-by-eight circuit.
— The measurement period is the same as for HCTR.
• When SF in the serial input data is set to 0:
— Period measurement mode is selected.
— Input frequency range: 1 Hz to 20 kHz (VIH = 0.7 VDD minimum, VIL = 0.3·VDD
maximum)
— The measurement can be selected to be for one or two cycles. If two cycle
measurement is selected the input frequency range becomes 2 Hz to 20 kHz.
(GT = 0: one cycle, 1: two cycles)
• Measurement results are output in the same manner as HCTR measurement results.
Note: *1. Since the output port states are undefined when power is first applied, transfer the control data quickly.
*2. The high and low level input voltages for the CE, CL, DI, IN0 and IN1 pins are VIH = 2.2 to 6.5 V and VIL = 0 to 0.7 V, regardless of the power
supply voltage VDD.
