National Semiconductor Showcases Advanced Analog Power Management, Lighting, Audio and Imaging Solutions for Mobile Phones at CTIA

Posted on: Monday, 15 March 2004, 06:00 CST

ATLANTA, March 15 /PRNewswire-FirstCall/ -- National Semiconductor Corporation will feature its newest technologies for mobile phones at the Cellular Telecommunications & Internet Association (CTIA) show in Atlanta, Georgia, which runs from March 22-24.

National is a leading supplier of analog and mixed-signal technologies in the global $20 billion (1) market for semiconductors used in cell phones. The company's products enable the world's major manufacturers to design cell phones with longer better battery life, sharp, crisp display images, smaller form factors, power-efficient lighting solutions and advanced user interfaces.

At CTIA, National will showcase a complete portfolio of analog solutions for cell phone makers, including:

-- Power Management: National's power solutions extend from

performance-leading single power converters to complete system-level

products. Using National's PowerWise(TM) technology and ARM's

Intelligent Energy Manager(TM) hardware/software solution, cell phone

makers can dramatically increase the features and functionality of

their handsets while maintaining the same size, weight and battery life.

-- Lighting solutions: White LED drivers from National are used to

backlight 65 percent of the color-screen phone handsets worldwide. At

CTIA, National will demonstrate the industry's most comprehensive

portfolio of lighting products. The demonstration will highlight

National's latest product, the LM2796 dual-display white LED driver,

which is ideal for lighting up to two displays plus a keypad. In

addition, National will feature lighting management units, RGB fun

lighting drivers and camera-phone flash drivers.

-- Audio amplifiers: With a portfolio of more than 100 products and

growing, National's Boomer(R) audio products are the industry's most

recognized name in amplifiers and are used by nearly every cell phone

maker in the world. At CTIA, National will feature its latest 3-D

stereo audio products, drivers for new speaker technologies, advanced

audio subsystems and high-efficiency amplifiers.

-- Mobile Pixel Link (MPL): At CTIA, National will demo its LM2501 camera

interface, a new product that uses power-saving Mobile Pixel Link

technology. This new technology also enables manufacturers to reduce

the number of wires needed for a camera phone from 12 to only three.

MPL products allow handset manufacturers to reduce system costs,

especially on expensive flex cables and reduced IC package and

connector sizes, while improving overall reliability.

-- Phase-locked loops (PLL) and Voltage Controlled Oscillators (VCO):

These critical ICs keep a phone locked on to a cellular signal for

strong, clear reception. National's PLLatinum(TM) family of PLLs will

be used in a large percentage of the 500 million cell phones sold

worldwide this year. At CTIA National will highlight the LMX2604, the

first member of a new family of voltage-controlled oscillators (VCOs).

This new chip is the industry's only stand-alone, monolithic VCO with

electrical performance suitable for mobile handsets and features a

footprint 80 percent smaller than alternative solutions.

-- Amp-in-a-Mic: Another first in consumer microphone electronics --

National technologies enable digital voice quality directly inside

electret condenser microphones (ECMs). Ideal for handsets and headsets,

National will demo its "amp-in-a-mic" products that improve performance

and save board space.
