LC72131K LC72131KMA
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.
