[TechView: The Industry]
Hot Product
Low-voltage portable applications like Bluetooth and other wireless systems can exploit the power-saving advantages offered by a new 1.8-V flash-memory family. Developed by Silicon Storage Technology, the devices trim power consumption to just 9 mW... — Dave Bursky

[TechView: Analog & Power]
Charge Pumps Efficiently Drive White LEDs
By employing dual-mode operation, the AAT3123/4 charge-pump white LED drivers achieve high efficiency over the discharge cycle of a lithium-ion battery. The chips combine a 1× load switch with a 1.5× fractional charge pump. During most of... — David G. Morrison

[TechView: Analog & Power]
ICs Better Video Distribution Over CAT-5 Cabling
The EL9110 differential receiver/equalizer from the Elantec division of Intersil integrates several functions needed to distribute video over low-cost CAT-5 unshielded twisted-pair (UTP) cables. In doing so, it offers a compact, low-cost alternative... — David G. Morrison

[TechView: Analog & Power]
Power Module Optimizes Performance For Itanium2 CPU
The HyperQor dc-dc converter module delivers up to 100 A or 130 W in a standard Intel pod package for powering the Itanium2 processor. Operating from a 48-V input, the dc-dc converter generates a programmable 0.9- to 1.7-V output. Full load... — David G. Morrison

[TechView: Communications]
3G Silicon Gives Bluetooth Green Light Into New Apps
Bluetooth continues to expand quietly into major wireless applications. The highest-volume applications are cell phones and wireless headsets. With many millions sold and Bluetooth prices at an all-time low, PC manufacturers like Apple and Dell... — Louis E. Frenzel

[TechView: Communications]
Voice Codec For RISC/DSP Core Handles All VoIP Operations On One Chip
Voice over Internet Protocol (VoIP) has arrived as equipment vendors break through the barriers of corporate telecom and IT infrastructure and politics. ARC International is hopping onto the VoIP rocketship with its voice coding library.... — Louis E. Frenzel
