MANHASSET, N.Y. The hottest products posted this week at www.eeProductCenter.com include a miniaturized AC/DC switching power supply that delivers 1 watt in standby mode, a USB flash drive line, a single-chip cellphone device that promises double talk time and a 14-bit, 150-MSPS analog-to-digital converter that consumes only 430 mW.
The top product this week is the latest addition to Bias Power's (Buffalo, N.Y.) BPS line of micro-sized AC/DC switching power supplies. Designed for standby mode and "green power" applications, the power supplies are available in 12- and 1-watt models. Up to 56 percent smaller than previous Bias models, the supplies measure about 1-by-0.87-by-0.5 inches.
The six models in the line deliver 8 or 14 volts (single-output), or 5 and 8 volts (dual outputs) from an 85 to 265 VAC input. The units power system clocks, IR remote receivers, membrane keypads, and LED panel lighting for test equipment, and audio and video equipment.
The BPS' proprietary design eliminates line EMI and no input filtering is required. No-load power consumption is less than 30 mW. Nominal operating efficiency is 75 percent.
Also drawing interest also is a line of USB flash drives that Toshiba Corp. (Tokyo) will be bringing to market later this year.
The four new models in the TransMemory U3 smart drive series will be offered in 512-MByte, 1-, 2-, and 4-GByte capacities. A corresponding line-up of flash drive subassemblies for OEMs will be offered that can be easily customized by adding the outer shell.
The U3 smart drive computing platform supports storage of not only data, but also of applications and personal computer settings, preferences, profiles and security features, as well as the means to manage them.
A U3 smart drive can be used in any Windows 2000 or XP PC with a USB slot, and once configured to suit a user's preferences, delivers the user's familiar computing environment and support for such applications as e-mail and web surfing, and access to files stored both on the host PC and on the smart drive. When the user removes the U3 smart drive, no personal data is left behind. On insertion into a PC, all U3 smart drives automatically launch the U3 Launchpad, which presents the user with a list of programs to choose from and files to work with.
Qualcomm's (San Diego) upcoming single-chip cell phone device promises double the talk-time. When it debuts next year, the QSC1100 will likely let CDMA2000 handset makers benefit from price barriers that had heretofore precluded some emerging markets worldwide. In addition to supporting features such as downloadable polyphonic ring tones, a speakerphone, and color displays, the QSC1100 promises to double talk-time compared to currently available CDMA2000 handsets.
Addressing dramatic subscriber growth anticipated globally, the QSC1100 will use multiple technologies (including 65-nm chip feature sizes) to improve network capacity by up to 100 percent. Multiple technologies will permit network operators to prioritize voice capacity or improve network capacity by up to 60 percent, or double the capacity within the same spectrum with the additional implementation of four-way receive diversity at base stations.
The device integrates a baseband modem, RF transceiver, power management circuits, and system memory into a single chip, thereby reducing the number of discrete components required. A fourth-generation vocoder is also included. The chip is also expected to reduce BOM (bill-of-materials) costs, and deliver board-area savings of more than 50 percent.
Other features will include support for voice/SMS (short messaging service), and support for downloadable so-called wallpapers. The device will also support multiple frequency operation, including operation in the 450-MHz, 800-MHz, 1.9-GHz, and 2.1-GHz bands.
Analog Devices (Norwood, Mass.) says its AD9254 14-bit, 150-MSPS analog-to-digital converter consumes only 430 mWa 50 percent reduction in power consumption over existing solutions.
Suited to WiMAX and picocell base station receivers, as well as ultrasound and handheld instrumentation equipment, the chip features 83-dBc SFDR (spurious-free dynamic range) at 70 MHz. In addition to achieving the highest SFDR in its class, the AD9254 has a signal-to-noise ratio of 72.7 dBFS at 70 MHz.
