USB Type-C PD 3.0 Specification, Charging and Design - EDN
WEBJun 25, 2021 · The first one—Power Delivery 2.0—supports fixed output voltages including 5, 9, 12, 15, or 20V at specific operating currents, for example 3 A. The second specification—PD 3.0—includes programmable power supply (PPS), a feature that allows the USB Type-C charger’s output voltage to be adjusted in …
Eye Diagram Basics: Reading, Analyzing and Applying
WEBDec 16, 2011 · An eye diagram is a common indicator of the quality of signals in high-speed digital transmissions. An oscilloscope generates an eye diagram by overlaying sweeps of different segments of a long data stream driven by a master clock. The triggering edge may be positive or negative, but the displayed pulse that appears after a delay period may go ...
Setup and Hold Time Basics - EDN
WEBApr 19, 2012 · Hold time is defined as the minimum amount of time after the clock’s active edge during which data must be stable. Violation in this case may cause incorrect data to be latched, which is known as a hold violation. Note that setup and hold time is measured with respect to the active clock edge only.
Cross Sectional Area Of Wire: Formula & Calculation - EDN
WEBNov 15, 2016 · How to find the cross sectional area of a wire. First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.”. Thus, 0.001 inch = 1 mil, 0.01 inch = 10 mils and so forth. Then we define the cross sectional area simply as the square of the wire’s diameter in mils ...
Setup and Hold Time Equations and Formulas - EDN
WEBAug 10, 2012 · Hence to fulfill the setup time requirement, the formula should be like the following. T c2q + T comb + T setup ≤ T clk + T skew (1) Let’s have a look at the timing diagram below to have a better understanding of the setup and hold time. Figure 2 Setup and hold timing diagram. Now, to avoid the hold violation at the launching flop, the data ...
Audio levels, dBu, dBV, and the gang: What you need to know
WEBApr 18, 2017 · Simply, they refer to the voltage levels defined as 0 dBVU. Unbalanced The standard consumer “-10dBV” standard means that 0 dBVU equals -10 dBV, or, using the dB-to-volts formula: = 1V • 10 (-10/20) = 316.2 mV. It so happens that this interface has been defined to carry 2V maximum (sine RMS, or 5.66 V P-P ).
Automotive HVAC & Cabin Climate Control System Basics - EDN
WEBDec 21, 2012 · Introduction. Heating, ventilation and air conditioning (HVAC) is the technology for indoor and automotive ambient comfort. HVAC facilitates in managing the pleasant climate inside the cabin by controlling the degree of hotness/coolness. There were times when having an air conditioner in a car was …
Burn-in 101 - EDN
WEBOct 14, 2014 · Burn-in testing is the process by which we detect early failures in components, thereby increasing component reliability. In the semiconductor world, this means taking us closer to zero DPPM. During burn-in, the component is exercised under extreme operating conditions (elevated temperatures and voltages). This stresses the component under test ...
The story of Jim Keller and his pioneering work on chip design and ...
WEBJan 9, 2021 · At SiByte, Keller pioneered the idea of dual-core designs, which placed two processors side by side on the same piece of silicon. A year later, in 2000, Broadcom acquired SiByte for $2 billion in stock and began shipping the dual-core chips in routers to move around huge amounts of data. Eventually, later in the decade, dual-core processors ...
