LAN Modules with Low Insertion Loss and High Interference Suppression Specifically for LAN applications, EPCOS has developed magnetic modules for both electrical isolation and suppression of common-mode and differential-mode interference. These modules are available in single, dual and quad-port versions and are qualified to IPC/JEDEC J-STD-020C and IEEE 802.3. The electrical isolation can withstand a breakdown voltage of 1500V AC.
SFDE
The insertion loss of the modules is only -1.0dB. Values of -16dB and -40dB are attained for return loss and crosstalk, respectively. In addition to the standard temperature range from 0ºC to +70°C, versions with an extended temperature range from -40ºC to +85°C were developed for industrial applications. Typical applications are 10/100 Base-T, 1000 Base-T as well as Power over Ethernet (PoE).
FEATURES
Ethernet Protocol is the common basis for data communication in LANs. The physical layer of the Ethernet is standardized in IEEE 802.3. Depending on the technology, different transmission speeds can be distinguished: 10 Base-T with 10Mbit/s, 100 Base-T with 100Mbit/s and 1000 Base-T with 1 Gbit/s transmission speed. IEEE 802.3af describes transmission of power via the Ethernet port. This technology is called Power over Ethernet (PoE) and is necessary to implement applications like Voice over IP (VoIP) where the phone is powered via the Ethernet connection. The transceiver chip side (PHY) and the medium side (connecting cable) must be galvanically isolated. EPCOS magnetic modules provide minimum 1500V dielectric isolation combined with excellent insertion and return loss as well as crosstalk and differential to common-mode rejection.

Application Spotlight
General Purpose Microwave MMIC LNAs The BGU7003 general purpose LNA uses NXP Semiconductors’ latest 110GHz Ft SiGeC microwave possessing technology QUBiC4X. The LNA is useful from 40MHz to 6.0GHz in home automation applications where high performance wireless links are a key requirement. Its small footprint, low cost and high performance make it an attractive alternative to devices that use GaAs technology.
APPLICATIONS
The BGU7003 is easily configurable to produce the balance of gain, current consumption and IIP3 required by RF and microwave receiver front ends. Its small size reduces the PCB footprint and reduces overall system cost. Its low noise and stable gain improves receiver sensitivity. Its high IIP3 reduces the requirements on front end filtering and susceptibility to jamming signals. An internal biasing circuit keeps current constant over a wide temperature range. Low active and shutdown current consumption allows for longer battery lifetime.
Summary at f = 1.575GHz
As the latest member of NXP’s growing SiGe:C portfolio, the BGU7003 joins the highly successful BFU725F device.

ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868MHz in Europe, 915MHz in countries such as USA and Australia and 2.4GHz in most jurisdictions worldwide. To extend the functionality of these devices into other application spaces, it is possible to trade low power consumption for range by adding an external Power Amplifier (PA) and/or a Low Noise Amplifier (LNA). The tables provide general guidance on selecting these external components. A major consideration is the selection of a PA and/or LNA, are the limits imposed by regional standards. In the US it is limited to 1W, in Europe 100mW and Japan 10mW. Adding an external PA and low noise amplifiers can increase the transceiver range to approximately 1.5 km.

High Speed Comparators with Rail-to-Rail Input/Output The MCP656x is a family of high speed (45ns) comparators with push-pull or open-drain outputs. The push-pull output of the MCP6561/1R/2/4 (single/dual/quad) family supports rail-to-rail output swing and interfaces with CMOS/TTL logic. The open-drain output of the MCP6566/6R/7/9 (single/dual/quad) family requires a pull up resistor and it supports pull-up voltages above and below VDD which can be used to level shift. The cost effective comparators are ideal for battery-powered applications requiring low power and high speed operation. Their low quiescent current of 100μA generates less heat, extends battery life and minimizes thermal-related challenges. With their low operation voltage (down to 1.8V), the comparators can be powered directly from the battery, allowing for full battery utilization. A rail-to-rail input/output structure provides greater dynamic range and better performance across the entire operating voltage range.

Enabling Low-Bay Lighting Leveraging LED Technology By Robert Zadeh, Technical Marketing Engineer, Future Lighting Solutions
Achieving a LED-Based Low-Bay Lighting System Background on Low-Bay Lighting Low-bay lighting is used in warehouse facilities, assembly areas, parking garages and workshop areas. All these applications typically require mounting heights of less than 3m. High Intensity Discharge (HID) lamps, High Pressure Sodium (HPS) lamps, fluorescent lamps and compact fluorescent lamps have been used until the recent years. Until the mid 2000s, the use of Light Emitting Diodes (LEDs) in general lighting applications such as street lighting, industrial factory floors and low-bay lighting was considered expensive and inconvenient. The reason was the inability of early LEDs to produce the required light output needed for such applications. As a result, it was considered costly to leverage the LED technology given the very high number of required LEDs. Recent years have seen drastic changes in LED lighting technology. It is now possible to achieve flux values of 100+ lm from a single LUXEON® Rebel LED driven at 350mA and flux values of 200+ lm from the LUXEON® K2 with TFFC LED driven at 1000mA. Hence, higher light output can now be achieved using lower power and smaller LED count. Moreover, the average LED lifetimes have improved significantly. This makes LED technology an ideal solution for low-bay lighting applications. This article focuses on the process of converting the existing low-bay lighting systems from conventional technologies to LED-based technology. The main goal is to meet the requirements such as light output, Correlated Color Temperature (CCT), efficacy and lifetime. Two power solutions will be presented: The first one, referred to as the basic power solutions, corresponds to turning the LEDs on and off and to efficiently achieving lighting requirements. The second one, referred to as the intelligent power solutions, will give users the flexibility of adding sensors, wireless control, and dimming.
Luxeon Rebel
Future Lighting Solutions has developed a LED-based low-bay lighting system leveraging 48 LUXEON Rebel LEDs and Carclo Bubble Optics, as shown in Figure 1. This demo unit has been tested and simulated according to the specifications of Table 1.

Meeting the Low-Bay Light Output Requirements Generally, there are two options available when selecting the number of LEDs and the drive current. The first one involves producing high efficacy (lm/W) by using high number of LEDs at low drive currents. The second one involves producing high light output (in lm) by using low number of LEDs driven at higher currents, which result in lower efficacy values.

The new SSL Designer software, available through Future Lighting Solutions at: www.futurelightingsolutions.com/ssldesigner takes the target light specifications such as the efficacy, illuminance, system lifetime, along with the maximum LED drive current as input parameters. It then determines the required minimum number of LEDs to meet the provided specifications. Moreover, it calculates the usable light (lm), the usable efficacy (lm/W), and the total power consumed by the LED-based system (W), amongst other output parameters. As shown in Figure 2(b), the SSL Designer has concluded that at a preset maximum current of 375mA due to the selected LED driver output current limitation, the LED-based low-bay lighting system requires 48 LUXEON Rebel LEDs to meet

In order to achieve a uniform illumination, the Carclo Bubble Optic (Part Number: 10403) has been utilized for each LED as shown in Figure 3(a). Its radiation pattern at a mounting height The LED part number, lumen maintenance, circuit of 2.5m is shown in Figure 3(b).

Figure 4 illustrates the thermal distribution across the matrix of 48 LUXEON Rebel LEDs used in the Optical Solution low-bay light system. The maximum LED junction The Full Width Half Maximum angle of LUXEON temperature in the model is calculated by QLED to Rebel is typically 140°. This provides a wide be 104°C. This is an indication that the calculated radiation pattern that is needed for the low-bay results of Figure 2(b) are accurate and below the maximum simulated value of junction temperature. This junction temperature is below the maximum rated value of 150°C for the LUXEON® Rebel LED. It is important to note that the LED-based lowbay lighting fixture simulation shown in Figure 4 assumes a sealed enclosure that does not allow any ambient air in. In order to compensate for the heat generated inside the fixture, a high ambient temperature of 72.5°C has been entered into and has been used by the SSL Designer to calculate the results of Figure 2(b).

Basic Power Solutions The basic power solution includes only ON/OFF functionality with no control or communications features. Referring to the requirements of Table 1, a universal LED driver is needed for powering the LEDs used in the low-bay light. The SSL1750 from NXP is an isolated Switched Mode Power Supply (SMPS) Controller Integrated Chip (IC), used to drive LEDs in low-bay lighting applications with power requirements of 25–250W. Figure 5 illustrates the evaluation board leveraging the SSL1750 IC. The SSL1750 is fed by the 60-Hz universal AC mains (110 – 227VAC ). With an efficiency of 85% and a Power Factor Correction (PFC) higher than 0.95, the SSL1750 will facilitate an AC to AC stepdown conversion. This will provide the constant current required by the LEDs.

Alternatively, a dual-stage AC-DC solution can be designed where the first stage will leverage the SSL1750 in voltage mode to provide a constant output voltage of 48VDC. The second stage will leverage four LM3402HV driver ICs from National Semiconductor to provide 4 constant current strings of 12 LEDs to drive the required 48 LEDs. Figure 6 illustrates the LM3402HV.

Motion and Ambient Light Sensing Ambient light sensors such as Avago’s APDS-9003 are used to detect light in the environment surrounding the LED-based low-bay lighting system. Supplied by 2.4–5.5V, they can be leveraged by the PowerPSoC in order to dim the LEDs if the ambient light is at high levels. Motion detectors, such as the NaPiOn Passive Infrared (PIR) from Panasonic can also be leveraged to help save power, and turn the light on when a person or an object enters the room or facility. Using this sensor, the LED-based low-bay lighting system will go into “power saving mode,” where light would be 30-50% dimmer. Upon the entrance of a person to the area, the motion detector would send signal via a wireless communications link to the LED-based low-bay light fixtures to return to 100% light output. This will help in conserving energy and prolonging the lifetime of the LEDs being used in the low-bay light system.

Enabling Wireless Communications Some LED-based low-bay lighting solutions may require wireless communications to control the low-bay lights or to receive information from the sensors.

Microchip Enables AC Measurement/ Metering with Product Line of ICs By Mark Hofmann – Microchip Dedicated AE, Future Electronics Microchip Technology, Inc., known for their industry leading 8-, 16-, and 32- bit microcontrollers, has introduced a line of products that can enable energy metering and energy measurement applications.
Energy Meter To Power Supply/VDD Generation To Voltage Divider, then to V Measurement (and calibration network)
Load Shunt
AC line power measurement, once relegated to utility meters, is finding applications in smart home/smart building and smart grid installations. Microchip Technology offers a range of metering solutions to fit your needs whether you are looking for a simple, cost effective way of measuring input power or if you are designing a Class 0.2 IEC compliant meter.
The following figure shows the implementation of a shunt type power meter. This meter is designed with the microprocessor ground as the ‘hot’ of the AC. The power for both the Energy Meter IC and optional processor is derived from the AC line. There are four measurements points that connect to the AC line, two for the voltage divider and two for the shunt.
AC Power Metering Basics Electronic meters are generally preferred over their mechanical counterparts due to more desirable attributes of the electronic system: • Reliability • Accuracy - Non-linear loads - Ease of calibration • Automated reading • Security • Advanced billing - Net metering - Time of use

Microchip Devices
Almost all power meters measure both voltage and current to calculate the power being delivered. The sum of this power over time is the energy that is consumed by the load. While measuring voltage in these systems is fairly straightforward, there is a decision to be made for measuring the current. Meters can either directly measure the current through a shunt or indirectly through the use of an isolation transformer. The tradeoffs of this decision of whether to use a shunt or transformer affects the design of the analog front end of the system. The shunt is essentially a piece of metal that acts as a sense resistor that can handle large currents. Typically this method is not used in meters with a maximum current of >100A.

To I Measurement
Meters using transformers can handle much more current than shunts and are more power efficient (usually energy companies only allow 2W of power consumption for residential power meters). However, they are more expensive and can be less accurate due to the properties of the magnetics. (saturation and phase response).

can be changed from 1x to 32x. The calculation of the active power, and the filtering associated with this calculation are performed in the digital domain, ensuring better stability and drift performance. Two digital high-pass filters cancel the system offset on both channels such that the real-power calculation does not include any circuit or system offset. After being high-pass filtered, the voltage and current signals are multiplied to give the instantaneous power signal. This signal does not contain the DC offset components, such that the averaging technique can be efficiently used to give the desired active-power output.
There are four different devices that Microchip offers for their energy metering applications: MCP3905A, MCP3905L, MCP3906A and MCP3909.

Metering Implementations The pulse outputs of the MCP3905/06/09 can directly drive electromechanical counters or two phase stepper motors. This allows these devices to work stand-alone in an installation. However when paired with a PIC microcontroller, there are greater opportunities for system flexibility. For instance, the MCP3905/06/09 devices connected to a PIC with an RTC allows for some advanced metering applications, such as time of use information. When coupled with a PIC and an integrated segmented LCD driver, the system allows greater communication between the user and the power being consumed. When connected to a PIC with an 802.11 module (Like the Silex SX-550), the meter could then attach to a wireless network and the user can see the power consumption in real time – either on their network or across the internet.
HFOUT
These devices are monolithic ICs that have two outputs, one for real power measurement and one for instantaneous power measurement. Both of these outputs are proportional to the input power, with the instantaneous power giving a much higher frequency output. Both input channels use 16- bit, second-order, deltasigma ADCs that oversample the input at a frequency equal to MCLK/4, allowing for wide dynamic range input signals. Typically MCLK is between 1-4MHz, and acommon low cost option is to use an NTSC 3.579MHz oscillator. A Programmable Gain Amplifier (PGA) increases the usable range on the current input channel and gain
