Overview

The LC72191, LC72191M and LC72191JM are PLL frequency synthesizers for electronic tuning. The LC72191, LC72191M and LC72191JM are optimal for AM/FM tuner circuits that require high mounting densities.

Features

Designed for use in car stereos, the LC72191 provides a rich set of reference frequencies, I/O ports, a general purpose counter, and an unlock detection circuit.

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.

• Package:

LC72191: DIP24S

LC72191M: MFP24

LC72191JM: MFP24S
