ON Semiconductor Introduces Power Line Carrier Modem SoC for Rapid Growth Smart Metering and Building Automation Markets

ON Semiconductor (Nasdaq: ONNN) a premier supplier of high performance silicon solutions for energy efficient electronics has introduced a new power line carrier (PLC) modem system-on-chip (SoC) for use in applications such as e-metering, home automation, solar energy and lighting control. The first device in a new family of PLC modems, the NCN49597 combines a low power 32-bit ARM Cortex M0 processor with a high-precision analog front end. Based on a dual 4800-baud S-FSK (Spread Frequency Shift Keying) channel technology, it has been optimized for power efficiency and performance, while providing excellent robustness and reliability to enable operation in the harshest environments.

The NCN49597 is fully compliant with the prevailing IEC61334-5-1 standard but also supports customized implementation of the popular building automation standard while keeping pin-to-pin and function compatibility with its predecessor, the AMIS-49587. The new device adds a host of innovative features such as field re-programmability, smart synchronization and automatic half baud rate detection that boost robustness of communication and make its implementation and use simpler. Programmable carrier frequencies in the CENELEC A to D bands and the ability to operate on both AC voltage, at either 50 hertz (Hz) or 60 Hz, and DC voltage enhance the range of applications for which the NCN49597can be utilized. This means a single device is suitable for all types of electrical power grids.10 configurable general purpose inputs / outputs (GPIOs) allow connection to peripherals such as LCDs and metering ICs and alleviate the need for external microcontrollers in applications such as smart plugs. The NCN49597 comes with open source PLC platform code and development environment.

ON Semiconductor also offers a PLC communication reference design kit including a power line driver helping customers to speed up their time-to-market. The NCS5650 is a 2 ampere (A) high efficiency class A/B power line driver that provides flexible 4th order filtering and current limiting, programmable with a single resistor.

According to the IHS iSuppli Industrial Market Tracker, industry-wide semiconductor revenues from smart electricity meters are estimated to be $559.6 million in 2012 and upwards of $1.1 billion annually by 2015. IHS iSuppli further forecasts that 24.9 million smart electricity meters will be installed in 2012, 57.3 million will be installed in 2015, and 66.6 million smart electricity meters will be installed in 2017.

“This innovative new device builds on ON Semiconductor’s 10 years of experience in the field of e-metering and offers a versatile and robust solution for enabling communications in the important and rapidly expanding smart grid market sector,” said Ryan Cameron, vice president of Industrial and Timing Products, ON Semiconductor. “Compatibility with our previous device for this sector plus full compliance with industry standards and the use of proven technology such as the ARM Cortex M0 processor make the utilization of the NCN49597 a risk-free and straightforward process.”

The NCN49597 operates from a 3.3 volt (V) power supply, has a junction operating temperature range of -40 ºC to +125 ºC and is housed in a QFN-52 package measuring 8 mm x 8 mm x 1 mm.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…
