CMOS IC
PLL Frequency Synthesizer
Overview
The LC72131K and LC72131KMA are PLL frequency synthesizers for use in tuners in radio/cassette players.
They allow high-performance AM/FM tuners to be implemented easily.
Features
High speed programmable dividers
FMIN: 10 to 160MHz …………………….. pulse swallower (built-in divide-by-two prescaler)
AMIN: 2 to 40MHz ………………………. pulse swallower
0.5 to 10MHz …………………….. direct division
IF counter
IFIN: 0.4 to 12MHz ………………………. AM/FM IF counter
Reference frequencies
Twelve selectable frequencies (4.5 or 7.2MHz crystal)
100, 50, 25, 15, 12.5, 6.25, 3.125, 10, 9, 5, 3, 1kHz
Phase comparator
Dead zone control
Unlock detection circuit
Deadlock clear circuit
Built-in MOS transistor for forming an active low-pass filter
I/O ports
Dedicated output ports: 4 Input or output ports: 2 Support clock time base output
Serial data I/O
Support CCB format communication with the system controller.

Note 1: Recommended crystal oscillator CI values:
CI120Ω (For a 4.5MHz crystal)
CI70Ω (For a 7.2MHz crystal)
The characteristics of the oscillation circuit depends on the printed circuit board, circuit constants, and other
factors. Therefore we recommend consulting with the anufacturer of the crystal for evaluation and reliability.
Note 2: Refer to "Serial Data Timing".
