Maxim's latest SerDes chipset for automotive infotainment systems

Maxim Integrated Products, Inc. launched the latest 3.12Gbps gigabit multimedia serial link (GMSL) SerDes chipset designers using traditional STP or lighter weight, lower cost of coaxial cable can support high-resolution car infotainment system.
Currently widely used in automotive design STP cable to transfer data to the automotive infotainment system display. However, more and more OEM manufacturers began to try to turn the coaxial cable program to make cost and weight reduced by more than 50%. Using Maxim's SerDes chipset, OEM manufacturers can continue to use STP cables in their design, and in the future design of the module without changing the device can be seamlessly converted to coax solutions. The chipset provides coaxial cable or STP cable drive capability 15 meters, providing ample headroom for reliable and flexible design. Each serializer and deserializer built-in spread spectrum function, can effectively improve the link in the EMI performance without external spread spectrum clock. Each serializer are capable of any of the series with the use of a deserializer, allowing the terminal to use a different interface link. In addition to providing a central and rear monitors high-resolution drivers outside the series chipsets can be used for mega-pixel camera system.

The main advantage

Reduce cable costs and weight: Each SerDes chipset can be used coaxial cable, so that the cable cost and weight reduced by more than 50%.

Supports high-resolution displays: the ability to drive 24 of 1920x720 pixel color monitor, improve safety and visual entertainment systems.

Longer cable transmission distance: chipset can reliably drive 15 m cable, extension 50% over competing solutions distance.

Very low EMI: Serial built-spread function, no external components to reduce EMI.

Industry Evaluation

Maxim Integrated Automotive Balagopal Mayampurath program, product line director, said: "Maxim provides system-level solutions for the automotive OEM manufacturers, the products can be designed to provide maximum flexibility for car manufacturers."

Nina Turner IDC research manager, said: "Consumers increasingly value when purchasing car connectivity and infotainment features, car manufacturers need cost-effective infotainment high-resolution video display solutions."

Both sides of protection can be extended TE effectively prevent spring wound spring

A global leader in connected areas TE Connectivity (TE) has introduced two new series of scalable spring, respectively, side and side protection can be extended to protect preloaded spring scalable spring, these two products use the same package, but different heights. Its high internal connector sidewall designed to resolve issues that customers often encountered when using a large number of spring, such as wrapping or deformation occurs during transmission.
Also known as a spring collet shielding, grounding springs or general grounding contact is a single contact, the inner surface of the connector is installed, used in almost all the small printed circuit board (PCB). It may be provided between the electronic component and the printed circuit board ground, to prevent electromagnetic interference (EMI) and noise caused by static electricity, while shielding the vibration from the motor, an antenna, speaker and microphone created. Which spring is also widely used in consumer electronics products, industrial equipment, household appliances, instruments and intelligent buildings.

Jennifer Love TE Consumer Electronics Division, Global Product Manager, said, "spring usually requires multiple simultaneous use in the previous design, the spring is prone wound, gloves operator often be spring hook to the edge. the latest reinforced sidewalls in the printed circuit board design can effectively avoid entanglement transfer process, to prevent deformation, thereby increasing productivity. as with most all spring product line suppliers in the market, TE these new products will effectively meet growing customer demand. "

Both new series of side protection can be extended collet key features and benefits include:

The whole product range can be used in packaging design easily modified according to the needs of the customer

Highly scalable range of side protection spring of 1.0 mm to 3.8 mm, side protection preloaded with highly scalable spring range of 1.4 mm to 3.0 mm, the two products are designed to meet diverse customer needs

Installation is simple, low cost, suitable for connecting multiple PCB.

Gold plated FFC cable replace traditional wiring harness

Gold plated FFC cable development increasingly recognized, and with the rapid development of technology, electronic consumer products are toward small size, high precision, light-based, ultra-thin and other aspects into the development and popularization of .FFC become gradually replace traditional wiring harness inevitable trend, from Japan and South Korea and other countries and gradually spread to mainland China, has developed rapidly in recent years, due to take up less space in the use of resistance, twists and turns, excellent performance, is now widely used in TV, DVD, CD-ROM drive, printers, fax machines, liquid crystal display screen, camcorders, digital cameras, phones, copiers, computers, scanners, wireless instrumentation audio-visual equipment and aerospace fields, FFC (flexible flat cable) mainly from the bridge signal transmission, and can be equipped with the appropriate connectors. currently in the industry, FFC mainly nickel wire, tin wire conductor molded cable, but due to signal transmission and tin whisker short circuit problem, LG, Samsung, Sony, Lite and other famous enterprises requirements next, most of the original suppliers are changing the traditional process, now use bare copper conductor, well after the entire volume of the cable outer hair nickel plating.

    This will increase product appearance and enhance signal transmission capacity, but also improve the hardness, conductivity, weldability, toughness, corrosion resistance and other contact points, more effective solution to the problem of tin whiskers.

Founded in 1995, Colorsunny Electronic Co.,Limited (China) Electronic CO., Limited is an engineering and manufacturing company focus on Precision Connectors, cables, signal wires and enclosures for computers, digital products, Medical equipment, war industry, finance products, telecommunications industries, and household appliance.

Description of how to handle phone cable fault

For many friends outside the industry, the mobile phone will be considered wrong if the point is bad, then abandoned, in fact, is the general problem may appear in the phone cable is connected to the motherboard to connect the phone line phone display, camera, key board and motherboard cable is cable. Display to see things that are controlled by the motherboard output, while the cable's role here. It is responsible for the data transmission between the phone and displays the motherboard.

     Phone cable fault performance, cable damage, nothing is broken, and both produce resistance, the former tend to be more intuitive, with the naked eye you can find, change, or fly line can be solved; If you are after a kinds of trouble on relatively little need to measure it to know. But parallel display circuit, if the small screen with a display case, display problems big screen will not be very complicated, because parallel lines, big screen and small screen are shared, if that screen has revealed that not, generally enable signal for each screen there is a problem, or the problem is the interface cable (which is in the Hall circuit is a good premise).
     For the video, is not displayed, no lights, no earpiece sound, no ringing, no boot, key failure, etc., we can say that it is the problem phone cable failure.
    Finally, and share test methods and conditions of phone cable, and the electrical measuring OK the product into the customer's mobile phone cases offer or real machine, and then fixed on the test machine together, according to customer specifications set a good flip angle and frequency, start testing machine to start the test. After at least 10,000 times per clamshell product once removed electrical measurement to verify break (when the customer has to provide real machine can boot test). To flip times last test failed when the product is not as life of the product.
