Freescale Semi Transfers MC13135 Wireless Technology to Lansdale


Phoenix, Ariz. - - Lansdale Semiconductor, Inc. president, R. Dale Lillard, announced today the availability the MC13135 wireless integrated circuit (IC), a popular frequency modulated (FM) receiver originally designed and built by Freescale Semiconductor, Inc.

Lansdale now has single-source rights to both globally market and continue to manufacture Freescale’s MC13135 IC.  The MC13135 is incorporated into Lansdale’s exclusive product life cycle management system. This unique quality control system guarantees form, fit, and function meets the original manufacturer’s design specifications. This assures a continuous source of high performance ICs to the worldwide electronics market. 

The MC13135 is the second generation of single chip, dual conversion FM communications receivers developed by Motorola. Major improvements in signal handling, received signal strength indication (RSSI) and first oscillator operation have been made. In addition, recovered audio distortion and audio drive have improved.  These receivers offer low noise, high gain and stability over a wide operating voltage range.

The MC13135 includes a Colpitts oscillator, voltage-controlled oscillator (VCO) tuning diode, low noise first and second mixer and local oscillator  ( LO), high gain limiting intermediate frequency (IF), and RSSI. The MC13135 is designed for use with an LC quadrature detector and has an uncommitted op amp that can be used either for an RSSI buffer or as a data comparator.

These devices can be used as stand–alone very high frequency (VHF) receivers or as the lower IF of a triple conversion system. Applications include cordless telephones, short-range data links, 2 way radios, wireless temperature sensors, and scanners.  This IC is available in the original product package configurations: PDIP or SOIC 24 pin package. 

The MC13135 is manufactured by Lansdale today using Freescale’s original characteristics to meet or exceed requirements for existing or new designs.  Using the Lansdale MC13135 eliminates the need to go to the time or expense of designing in a replacement device, or doing a complete redesign and qualification in existing end products or systems.
