As the GSM/GPRS marketplace continues to expand, market requirements are increasingly demanding: products need to be smaller in form factor, more cost effective, and delivered to market quickly. There is also a drive to increase functionality, which pushes the need for integration, to meet both cost and size requirements. National Semiconductor has leveraged its strength as the premier analog company, with industry-leading products in power management and RF, to develop broad expertise in total system solutions for GSM/GPRS technologies.
Component Highlights
* LDOs - best-in-class dropout, excellent near-dropout PSRR, low noise, low quiescent current, and fast turn-on time provide high-quality regulation for the RF stage.
* White LED drivers - efficient, low noise, simple to drive, and product brightness matching and color uniformity in chip-scale packaging.
* Switched-capacitor converters, Buck switching regulators - high-efficiency power-saving solutions extend battery life.
* Boomer® audio amplifiers - as individual components or complete subsystem, Boomer amplifiers handle all the audio needs of the handset.
* PLL Loop Filter - single-integer, dual-integer, and fractional PLLs have low current consumption and excellent phase- noise performance. Integrated PLL+VCO simplifies the design process and greatly decreases board space.
* PA Loop Control - low current consumption solutions feature 0.1uA shutdown current.
* Thermal management - analog and digital devices minimize power consumption and board area.
* Bluetooth® technology - flexible options meet the needs of many customers, from standard products to customizable products to full custom ASICs. |
