| New Power Line Transceiver in Singapore building STMicroelectronics announced that its ST7538P Power Line Transceiver will be used in a home-automation system for the 70-story 'The Sail @ Marina Bay' apartment building. The Building, which is under construction on the Singapore waterfront, is due for completion in 2008 as the tenth tallest building in the world. The home-automation system, supplied by The Legrand Group, allows different advanced dynamic room scenarios, with lighting, air conditioning, rolling shutters, and many other room-automation features managed remotely through a personal computer or a WAP-enabled mobile telephone. At the heart of the Legrand kit is ST's ST7538, the single-chip Frequency Shift Keying power line transceiver, which integrates the modem section, the analog front end, the power amplifier and a variety of frequency synthesis, core logic, voltage regulation, and input/output functions. Embedded output current and voltage control loops ensure safe and reliable transmission over existing domestic power lines, where unpredictable impedance changes may occur. The power amplifier integration and a range of selectable additional functions - including Zero-Crossing detection, Carrier and Preamble detection, Band-in-Use detection, Watchdog Timer and Time Out - allows compact and cost-effective home and building automation systems, designed in accordance with specifications defined by the European Committee for Electrotechnical Standardization. The ST7538 supports many proprietary or open communication protocols based on FSK modulation schemes, among which are EHS and KONNEX. The ST7538P, produced using a 0.6-micron mixed-signal power technology, is characterized for the -40 to +85°C temperature range and is available in a TQFP44 lead-free package. write your comments about the article :: © 2006 Construction News :: home page |
