CMOS LSI
LC72133M, 72133V
PLL Frequency Synthesizer for
Electronic Tuning
Overview
The LC72133M and LC72133V are a phase-locked loop
frequency synthesizer LSI circuits for use in radio tuners.
It supports low-voltage (2.7 to 3.6 V) operation and can
implement high-performance AM/FM tuners easily.

• 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.

Local oscillator
signal input
— 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.
2 Chip enable
Set this pin high when inputting (DI) or outputting (DO)
serial data.
4 Clock
• Used as the synchronization clock when inputting (DI) or
outputting (DO) serial data.
