Background information

The NXP PNX4903 enables a music phone with color screen in the ultra-low-cost market segment. By integrating the analog and digital basebands, RF transceiver, power management, and audio circuitry in a single monolithic IC, the PNX4903 solution delivers the smallest bill of materials and PCB footprint, along with the lowest manufacturing and test costs.

The only external ICs needed are a power amplifier and memory. A complete, dual-band GSM/GPRS modem can be realized with just 49 external components on a low-cost four-layer PCB. Traditional multi-chip handset designs require three times the number of external components on a more complex PCB.

The hardware reference design is accompanied by a flexible, pre-integrated and validated software complement that reduces R&D expense and speeds time-to-market.
