| | Diodes Incorporated Introduces LED Driver Family | | Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, introduced a family of LED driver ICs capable of significantly reducing the number and size of external components required by driver circuits. The AP880X step-down DC-DC converters require the support of only four components and operate at switching frequencies up to 600kHz, which enables the use of smaller, lower cost inductors and capacitors. | | Leer la noticia completa | 24 de Mar de 2009 - 02:07 PM | |
| Ethernet-over-SONET/SDH Mappers Reduce Overall Cost for Delivering New Ethernet Services | | Maxim Integrated Products (NASDAQ: MXIM) introduces the DS33M30/DS33M31/DS33M33, a family of highly integrated Ethernet-over-SONET/SDH (EoS) mapping devices. These mappers merge new protocols for transporting Ethernet with the protocols of legacy optical networking, allowing service providers to deliver new Ethernet services using the existing optical transport infrastructure. They are the industry's first monolithic SONET/SDH mapping ICs to support the Ethernet-over-PDH (EoPDH) protocol over optical networks. The DS33M31 and DS33M33 both have a 17mm x 17mm footprint, with the DS33M33 including three additional DS3/E3 add/drop interfaces. The DS33M30 lacks the DS3/E3 functionality, but is the industry's smallest EoS mapper at a mere 10mm x 10mm. All three devices require only a minimal number of external components to implement a complete Gigabit Ethernet to OC-3/STM-1 solution, and provide an ideal solution for Ethernet access equipment, multiservice provisioning platforms, microwave radios, and IP DSLAM uplinks. | | Leer la noticia completa | 24 de Mar de 2009 - 01:56 PM | |
| STMicroelectronics Announces Commitment to Continue Minimizing the Environmental Effect of Set-Top Boxes | | STMicroelectronics (NYSE: STM), the world’s leading supplier of silicon chips for set-top boxes (STBs), and a Company well known for its global program for continuously reducing the impact of its operations on the environment, today extended its commitment to saving energy to STB applications. ST supports the moves toward an assessment of STB performance through total energy consumption as used in other sectors of the consumer electronics industry. | | Leer la noticia completa | 24 de Mar de 2009 - 01:53 PM | |
| Freescale introduces RFICs for 2 GHz wireless applications | | Freescale Semiconductor today introduced LDMOS driver amplifier RFICs designed to set new standards for video bandwidth, gain and efficiency for broadband networks. These advanced RF devices are ideal for such wireless applications as Multi-Carrier GSM, W-CDMA and the LTE enhancement to UMTS. | | Leer la noticia completa | 23 de Mar de 2009 - 01:17 PM | |
| 14-Bit Converter Performs Direct Digital Synthesis For RF Signals To 3.6 GHz | | Analog Devices, Inc. (NYSE: ADI), the global leader in data-conversion technology, today introduced a pair of 14-bit DACs (digital-to-analog converters) that perform direct digital synthesis for signals up to 3.6 GHz. These high-performance converters extend ADI’s industry-leading TxDAC® family** of transmit digital-to-analog converters by delivering an unmatched combination of usable bandwidth and effective dynamic range to communications-equipment manufacturers worldwide. | | Leer la noticia completa | 23 de Mar de 2009 - 01:13 PM | |
| Micro power consumption 4 or 5-wire touch screen controller | | Asahi Kasei EMD Corporation (AKEMD) today launched the AK4186, a low operating voltage resistive touch screen controller (TSC). This new device, an enhanced version of the widely-used AK4183, includes both 4-wire and 5-wire touch screen control interfaces. It is ideal for limited-space smart-phone touch screen applications, reducing PCB space by 80% using a micro CSP package. | | Leer la noticia completa | 23 de Mar de 2009 - 01:11 PM | |
