CMOS IC
LC72121MA PLL Frequency Synthesizers for
Electronic Tuning
Overview
The LC72121MA are high input sensitivity (20mVrms at 130MHz) PLL frequency synthesizers for 3V systems.
These ICs are serial data (CCB) compatible with the LC72131K/KMA, and feature the improved input sensitivity and
lower spurious radiation (provided by a redesigned ground system) required in high-performance AM/FM tuners.
Features

FMIN: 10 to 160MHz ·················· Pulse swallower technique (With built-in divide-by-2 prescaler)
AMIN: 2 to 40MHz ····················· Pulse swallower technique
0.5 to 10MHz ·················· Direct division technique
IF counter
IFIN: 0.4 to 15MHz ····················· For AM and FM IF counting
Reference frequency
One of 12 reference frequencies can be selected (using a 4.5 or 7.2MHz crystal element)
1, 3, 5, 9, 10, 3.125, 6.25, 12.5, 15, 25, 50, and 100kHz
