LC72140, 72140M

PLL Frequency Synthesizers

Overview

The LC72140 and LC72140M are high-performance, phase-locked loop (PLL) frequency synthesizers that operate over the VHF, MW and LW wave bands. They feature excellent frequency tracking, making them ideal as a reference frequency source for use in AM/FM radio receivers. The LC72140 and LC72140M operate from a 5V supply. The LC72140 is available in 24-pin DIPs, and the

LC72140M, in 24-pin MFPs.

Features

•High-speed programmable dividers for

·10 to 160MHz on FMIN using pulse swallower.

·0.5 to 40.0MHz on AMIN using pulse swallower and direct division.

•General-purpose counters (used together with the SD in IF count mode).

·HCTR for 0.4 to 25.0MHz frequency measurement.

·LCTR for 10 to 500kHz frequency measurement and 1Hz to 20kHz period measurement.

•4.5 or 7.2MHz crystal.

•Twelve selectable reference frequencies (1, 3, 5, 9, 10, 3.125, 6.25, 12.5, 25, 30, 50 and 100kHz).

•Phase comparator.

·Insensitive band control.

·Unlock detection.

·Sub-charge pump for high-speed locking.

·Deadlock clear circuit.

•C2B input/output data interface.

•Power-ON reset circuit.

•Built-in MOS transistor for a low-pass filter.

•Inputs/outputs (using five general-purpose input/output ports).

·Maximum of seven inputs.

·Maximum of seven outputs (three n-channel open-drain and four CMOS outputs).

•5V supply.

•24-pin DIP (LC72140) and 24-pin MFP (LC72140M).
