 As the cellular 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 cellular 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 0.1µA 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. 1 Pack Electronics LM3655TL LM3655TLX LM3658SD 2 PLL LMX2310U LMX2311U LMX2312U 3 PLL + VCO LMX2531LQ1570E LMX2531LQX1570E LMX2531LQ1650E 4 Active Filter LMP7711 LMP7712 LMP7715 5 Camera Flash LM2622 LM2623 LM2698 6 Thermal Mgmt LM26 LM27 LM45 7 DSP Bucks LM2612 LM2612BL LM2614 8 Speaker / Handsfree LM4820-6 LM4845 LM4864 9 Stereo Headphone LM4809 LM4810 LM4811 10 Ringer LM4820-6 LM4845 LM4864 11 Audio Subsystem LM4855IBL LM4855IBLX LM4855LQ 12 Modules LMV225TL LMV225TLX LMV226TL 13 Amplifiers LMV710M5 LMV710M5X LMV711M6 14 AMP LMV1012 LMV1015 LMV1032 15 Bluetooth National’s 2.0 and 1.2 Bluetooth certified products include the LMX5453 (Bluetooth 2.0) and LMX5452 (Blutooth 1.2) Micro-module and LMX5252 (Bluetooth 1.2 and 2.0) Radio Transceiver. These are targeted for designs that require high performance, small size, low cost and very low power solutions.
