Lansdale Sole Source for Motorola SPS (Semiconductor Products Sector) Wireless ICs
PHOENIX, AZ - Lansdale Semiconductor, Inc. president, R. Dale Lillard, announced today the continued availability of the ML3371 and ML3372 Low Power Narrowband FM IF (Frequency Modulation) (Intermediate Frequency) circuits originally designed and built by Motorola Semiconductor, Inc.  Lansdale has single-source rights to both globally market and continue to manufacture Motorola’s line of FM IF Circuits designed for FM dual conversion communication equipment.  These circuits continue supporting present customers and can be used for new designs.

The availability of these two ICs (Integrated Circuits) is critical in supporting a variety of applications ranging from radio receivers to test equipment.  The ML3371 and ML3372 are similar to MC3361 and MC3357 except that a signal strength indicator replaces the scan function controlling driver which is in the MC3361/MC3357.

The ML3371 is designed for use of parallel LC (Inductor-Capacitor) components, while the ML3372 is designed for use with either a 455 kHz ceramic discriminator, or parallel LC components.  These devices also require fewer external parts than earlier products.  The ML3371 and ML3372 are low power receivers designed to operate up to 60 MHz.  Its low voltage design provides low power drain, excellent sensitivity and good image rejection in narrowband voice and data link applications.  These parts combine a mixer, an IF (intermediate frequency) limiter with a logarithmic response signal strength indicator, a quadrature detector, an active filter and a squelch trigger circuit.  In typical application, the mixer amplifier converts an RF (Radio Frequency) input signal to a 455 KHz IF signal.  Passing through an external bandpass filter, the IF signal is fed into a limiting amplifier and detection circuit where the audio signal is recovered.  The ML3371 and ML3372 are available in dual-in-line and surface mount packaging. 

Lansdale’s exclusive product life cycle management system is a quality control system that guarantees form, fit, and function equal to the original manufacturers design specifications.  The Lansdale model has become increasingly important as the growth of the counterfeit industry has increased the problem of maintaining a reliable source of components for long-life systems.  “With counterfeit electronic components becoming more of a global industry nightmare, Lansdale’s 30 plus years of product life cycle management, support and manufacturing using only the OEM’s (Original Equipment Manufacture) original tooling has become even more critical in today’s market” stated Lillard.  This assures a continuous source of high performance IC’s to the worldwide electronics market.
