PLL Frequency Synthesizer
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 general­purpose 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.
