LC72121MA
CMOS IC
PLL Frequency Synthesizers
for Electronic Tuning
http://onsemi.com
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
High-speed programmable divider
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
