PLL Frequency Synthesizer
for Electronic Tuning in AV Systems
LC7218, 7218M, 7218JM
Overview
The LC7218, LC7218M and LC7218JM are PLL
frequency synthesizers for electronic tuning. The LC7218,
LC7218M and LC7218JM are optimal for AM/FM tuner
circuits that require high mounting densities.
Features
These products feature a rich set of built-in functions for
AV applications, including reference frequency and
unlock detection circuits, I/O ports and a general-
purpose counter.
Functions
Programmable dividers
— FMIN pin: 130 MHz at 70 mVrms and 160 MHz at
100 mVrms input (built-in prescaler)
— AMIN pin: Pulse swallower and direct division
techniques
Reference frequencies: Ten selectable frequencies:
1, 5, 9, 10, 3.125, 6.25, 12.5 25, 50 and 100 kHz
Output ports: 7 pins
Complementary outputs: 2 pins
N-channel open drain outputs: 5 pins
Input ports: 2 pins
General-purpose counter: For measuring IF and other
signals (Also used for station detection when
functioning as an IF counter.)
— HCTR pin: Frequency measurement (for inputs up
to 70 MHz)
— LCTR pin: Frequency and period measurement
PLL unlock detection circuit
Detects phase differences of 0.55, 1.11, 2.22 and 3.33 μs.
Controller clock output: 400 kHz
Clock time base output: 8 Hz
Serial data I/O
— Supports CCB format communication with the
system controller.
