Qualcomm Introduces Low Power 2.0 GHz Phase-Locked Loop Frequency Synthesizer

1 de Fev de 1996SAN DIEGO

Qualcomm products mentioned within this press release are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

Qualcomm Incorporated today announced its new Q3236 Phase-Locked Loop (PLL) Frequency Synthesizer, a high speed, low power, single-chip solution for high performance communications systems. The Q3236 combines low power consumption and ultra-low phase noise to allow communications engineers to easily customize their designs.

With less than 0.6 Watts of nominal power required and an operating speedup to 2.0 GHz, the Q3236 is well-suited for a variety of applications including cellular and paging base stations, frequency hopping systems, digital radios and modems, lab instrumentation and local oscillators for Very Small Aperture Terminals (VSAT), Direct Broadcast by Satellite (DBS), Global Positioning Systems (GPS) and radar.

The Q3236 phase-locked loop has three programmable control interface options including direct parallel, 8-bit bus and serial loading. Included on the chip is a high gain linearized phase/frequency detector operating to 100 MHz and divide-by 10/11 dual-modulus prescaler with programmable feedback divider. These features allow PLL designs to have smaller Voltage-Controlled Oscillator (VCO) division ratios to optimize synthesizer phase noise performance. They also simplify wider loop bandwidth designs to achieve faster switching speeds.

Using a single +5 Volt power supply, the highly integrated architecture of the Q3236 contains all of the necessary elements, with the exception of the VCO and loop filter components, to build a PLL Frequency Synthesizer operating from UHF through L-Band. Packaged in a 44-pin PLCC, the Q3236 operates over the industrial temperature range (-40°C to +85°C). The Q0410 and Q0420 PLL evaluation boards are also available for either fixed demonstration or custom prototyping.

Pricing for the Q3236I-20N is as low as $29.95 in 100 piece quantities. Samples are available now. Production quantities will be available in February, 1996.

Headquartered in San Diego, Qualcomm develops, manufactures, markets, licenses and operates advanced communications systems and products based on its proprietary digital wireless technologies. The Company's primary product areas are the OmniTRACS® system (a geostationary satellite-based, mobile communications system providing two-way data and position reporting services), CDMA wireless communications systems and products and, in conjunction with others, the development of the Globalstar low-earth-orbit (LEO) satellite communications system. Other company products include the Eudora Pro™ electronic mail software, VLSI components, and communications equipment and systems for government and commercial customers worldwide.
