Wireless high-definition video: silicon consolidation that's maximal

The Wireless Gigabit Alliance’s 60-GHz-based high-definition wireless-video-transport scheme may be on the way, but SiBeam’s pioneering approach and multiple product generations are already on the scene (see “The quest for robust wireless high-def video connections,”EDN, Sept 23, 2010, pg 32). Peer inside a SiBeam-developed reference design to see how the company accomplishes this hefty bit-rate trick, complete with support for 3-D video presentations and for equipment control and networking augmentations.The transmitter and receiver, each measuring 9×6×1.5 in., are identical except for backpanel labels that identify them as “source” and “sink,” respectively. An external ac adapter with 12V and 1.7A maximum output specifications powers each of them.

1. Take off the top covers of the transmitter’s and receiver’s enclosures, and you’ll find that a USB (Universal Serial Bus)-interface PCB (printed-circuit board) takes up most of the internal space. This debugging and control board mates with PC-side software, and production-system designs won’t need it. Such designs can be substantially smaller, less costly, and more power-thrifty as a result.

2. Behind the units’ plastic front panels and underneath intermediary metal shields that block all but the transmitting and receiving antenna arrays are 22×125×6-mm PCBs containing the core circuitry for each device. In this case, too, however, some of the silicon content is exclusive to the evaluation task and won’t appear in a production design. To wit, the top sides of both the transmitter and the receiver modules include Atmel AT91SAM256 microcontrollers to implement stand-alone operation. In an end-customer design, such as a Blu-ray player, a set-top box, a television, or an integrated home-theater setup, the system processor will typically manage the module, making the dedicated microcontroller unnecessary.

Circuit protection for LCD-TV backlighting, supplies - Electronic Products

Advanced LCD technology has resulted in larger screens, wider viewing angles, and higher-quality video images. However, as LCD-TV screens grow bigger and brighter, they require more voltage and current to operate, increasing the need for more robust and reliable circuit protection techniques.

A variety of circuit protection devices can be used to help protect the LCD screen from damage caused by excessive current or voltage transients. Overcurrent protection may take the form of a fuse or a resettable polymeric positive temperature coefficient (PPTC) device. Deciding whether to specify a PPTC device or a single-use fuse depends on the LCD design and the types of threats the device may face.
PPTC devices are commonly applied to circuits that experience high inrush currents on startup. PPTC devices are resilient to inrush currents and help eliminate the nuisance of blown fuses. Fuses are well suited to circuit designs where resettability is not desirable, or where faults occur only in a system failure condition. They are also a practical solution when soft-start circuitry is used to limit inrush current.
To enhance equipment safety and reliability, a variety of overvoltage protection devices including metal oxide varistors (MOVs), multilayer varistors (MLVs) and electrostatic discharge (ESD) surge protection devices can be used in a coordinated scheme with overcurrent protection devices, as discussed here.

Industry’s first reflowable thermal protection device replaces power FETs

Presented as the industry’s first surface-mountable reflowable thermal protection device, the RTP200R120SA (RTP200) can be used to replace redundant power FETs, relays, and heavy heat sinks. The first device in the RTP product family, the RTP200 can withstand multiple reflow passes with peak temperatures exceeding 200°C, and will also open when it detects temperatures above 200°C.

Field Effect Transistor Tester

This picture of Field Effect Transistor Tester came from Mr. Beh. I shared to him the circuit link and he makes one. Before he made one of this tester. He has a circuit that he plan to build it. But prior to that i told him that circuit of fet tester is not working because i made that one before. And I told him this picture which i link him the circuit that works to test a FET. Thanks to Mr. Beh for the picture. Congratulations. You have another helper to troubleshoot electronics.

Datasheet Book for Electronic Components

It is important to have datasheet book for electronic component to know what component are you dealing with if it is fet, darlington transistor, bipolar transistor, voltage regulator, scr, triac,diac,ic and so on. The importance of these books can give you easy access what is the pin names of your component you are dealing and thru this data given you can understand how it's work. You will know what is the input and output voltages like in IC datasheets. You will know also the specification of that component like the voltages it can withhold, wattage,ampere and so on. Some datasheet books gives you the replacement for some parts incase you cannot found in the market the original parts. While in this days most datasheets can be found in the internet thru typing the partname in google it is advisable that you have one of this book on your hand for easy and fast retrieving of the data you are looking for. Incase of electricity blackout or your computer will malfunction in the time you will not expected you have data on your hand thru these books..
