Diodes Introduces Voltage-potential Converters for Non-directional Flexibility Between Networks and Servers

Diodes, Inc. (Nasdaq: DIOD) today announced a new line of low-voltage potentiometric converters that enable simple, autonomous bi-directional operation. The PI4GTL2002 is a 2-bit potential converter designed to convert a signal used to regulate a voltage potential to a higher or lower voltage signal, such as converting a Transceiver Transceiver Logic (GTL) or GTL+ to LVTTL/ TTL. As the trend of top processor manufacturers adding GTL+ interfaces to their products continues to rise, the demand for high-performance potential converters in server/data center and network applications is increasing. PI4GTL2002 not only meets this need, but also brings the advantage of not requiring control.

The open-drain design of the PI4GTL2002 means that the device can convert voltage potentials from any direction without increasing the design complexity of the dedicated directional control signals, without sacrificing performance. The device is operatively unrestricted and can be converted between 0.8V and 5V (CMOS) with a propagation delay between input and output of no more than 1.5ns. As a result, PI4GTL2002 supports a variety of use cases, including standard mode and fast mode I2C interfaces.

In the design of this product, the NMOS-based transfer transistor will achieve bidirectional operation through the common gate, and provide a reference voltage for the two signals. This allows the design team to apply different voltages across the device, allowing the device to convert between signals between 0.8V and 5V.

PI4GTL2002 uses a straight-through design that is easy to arrange, which simplifies PCB configuration. The device's low input and output capacitors keep the transmission delay very low, and the 3.5Ω on-resistance minimizes signal distortion.

PI4GTL2002UEX is available in U-QFN package, while PI4GTL2002 & GTL2002GM+125 are available in W-QFN (PI4GTL2002WEX) and XT-QFN (PI4GTL2002XTEX) packages.

Vicor Introduces the Latest 800V bus Converter Module

The 800V BCM4414 is a 1.6KW isolated, 1/16 fixed ratio bus converter module (BCM®) that operates smoothly from 500V to 800V input voltage and provides SELV output voltage with a peak efficiency of 97%. The new 800V module is a powerful addition to Vicor's existing 700V BCM4414, which creates a range of products with greater isolation (4,242VDC) and bidirectional voltage conversion. The BCM can be easily paralleled into a higher power array, while the SELV output can be stacked (in series) for higher output voltages. Both BCMs are packaged in a 111 x 36 x 9.3 mm VIATM (Vicor Integrated Adapter) package that integrates PMBusTM communication, EMI filtering, and voltage transient protection. VIA's planar form factor package simplifies thermal management and easily interfaces with a variety of different cooling technologies. The BCM can be used for both military (-55 to 100 ° C) applications and communication (-40 to 100 ̊ C) applications. High pressure BCM series Mode...

Why Computer/Cell Phone manufacturer, TSMC support Huawei?

圖片
In the face of US sanctions against Huawei, the problem of ARM command set authorization, Bluetooth, WiFi authentication and so on is not the most deadly. As we all know, Huawei itself does not manufacture chips. Therefore, Huawei's weakest link relies on Computer/Cell Phone manufacturer, TSMC's advanced chip process foundry. Therefore, TSMC's response has received attention from all parties. Computer/Cell phone chip manufacturer support Huawei According to previous news, Huawei Kirin 985 will be the first to apply TSMC 7nm+ EUV technology, which is expected to be used in the Mate 30 series. In addition, Apple's A13, Qualcomm's Opteron 865 is also expected to use the upgraded 7nm process. TSMC officially announced that it has begun mass production of 7nm N7+ process. This is not only the first time that TSMC has produced EUV EUV lithography technology in the industry, but also has significant significance. It indicates that TSMC's foundry level ...

Top 8 Semiconductor Companies in the World

I will list 8 s emiconductor companies in the world. 1) Intel Intel Corporation (NASDAQ: INTC) is a device manufacturer that designs and manufactures motherboard chipsets, network interface controllers and integrated circuits. The company is headquartered in Santa Clara, Calif., and was established in 1968 by US venture capitalist Arthur Locke to arrange $2.5 million in funding. 2) Samsung Samsung actually consists of about 70 companies. Samsung Electronics produces mobile devices such as smartphones and produces TVs and appliances. The company also created semiconductors. 3) Taiwan Semiconductor TSMC (NYSE: TSM) claims to be the world's largest dedicated, independent, pure semiconductor foundry. The pure play foundry only manufactures integrated circuits and does not have any internal design capabilities. 4) Qualcomm Qualcomm, Inc. (NASDAQ: QCOM) Design and market wireless communications products and services. Global telecommunications companies us...
