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

Note 1: Recommended crystal oscillator CI values:
CI≤120Ω (For a 4.5MHz crystal)
CI≤70Ω (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".
