PNX4901

Enable a new generation of feature-rich ULC+ phones

NXP Semiconductors. 

The result is a phone that offers highly desirable features at

a dramatically lower price point than previously achievable,

and expanding the reach of these technologies to millions

more consumers in emerging and developed markets.

The PNX4902 lets OEMs and ODMs differentiate themselves

and their products in a fiercely competitive market.

Industry-leading integration and performance

As part of the PNX490x family, NXP’s family of innovative

single-chip GSM/GPRS solutions, the PNX4902 continues

to provide industry-leading integration, best-in-class RF

performance and power consumption, and an R99-compliant

communications protocol stack that is field-tested on more

than 100 networks across all major geographic markets.

The very high level of integration dramatically reduces

the number of external components. The only external ICs

necessary are a power amplifier and memory. A complete

triband GSM/GPRS modem can be created with just 50

external components, including passives and other discretes.

A better end-user experience

Several features of NXP’s highly integrated core architecture

let the PNX4902 deliver a more enjoyable end-user experience.

The PNX490x series is the only set of single-chip solutions that

obtains such a high level of integration while maintaining best-

in-class RF performance. They deliver significant margin to key

GSM specs across commonly encountered stress conditions in

the field, including extreme temperature and battery voltage.

They maintain excellent call quality in congested, urban

environments as well as in remote areas with sparse network

coverage. Additional features, such as SAIC, boost network

capacity even further. Superior echo cancellation and excellent

noise suppression make every call clearer, even in public spaces

and other noisy environments.

Plus, industry-leading power consumption means the battery

lasts longer, so consumers can spend more time talking

between battery recharges. With a small, inexpensive 600-mAh

battery, five hours of talk time and over 420 hours of standby

time are possible.

For the fastest possible time-to-market, the PNX4902 hardware

reference design is accompanied by a flexible, pre-integrated, and

fully validated software solution that also reduces R&D expenses.
