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 …
How to Measure Electrical Power - EDN
WEBAug 9, 2012 · Power Measurement Basics. DC power measurement is relatively simple as the equation is simply watts = volts x amps. For AC power measurement, the power factor (PF) introduces complexity as watts = volts x amps x PF. This measurement of AC power is referred to as active power, true power or real power. In AC systems, multiplying volts x …
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.
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 ...
What is ambient temperature, anyway, and why does it matter?
WEBAug 26, 2010 · The temperature of the board or chassis of the system, which is considered to never rise above a certain maximum temperature. The temperature of the air (usually driven by fans) at the entry or exit of the system. The temperature of the room when a component or system is tested on the bench, on an evaluation module (EVM) or a real system board ...
Equalization Techniques: CTLE, DFE, FFE, and Crosstalk - EDN
WEBOct 21, 2015 · DFE (decision feedback equalization) uses a decision circuit as part of its feedback loop. CTLE technology doesn’t change for PAM4 signaling. Tx FFE doesn’t change in principle, though with four different symbol levels, it changes in practice. But with four distinct “decisions” to feed back to the decision circuit, DFE differs for PAM4.

Clock Domain Crossing Techniques & Synchronizers - EDN
WEBSep 30, 2014 · In general, a conventional two flip-flop synchronizer (2-FF) is used for synchronizing a single bit level signal. As shown in Figure 1 and Figure 2 , flip flop A and B1 are operating in asynchronous clock domain. There is probability that while sampling the input B1-d by flip flop B1 in CLK_B clock domain, output B1-q may go into metastable state.
Solyndra: Its technology and why it failed - EDN
WEBNov 21, 2011 · Solyndra was a darling of clean tech but filed for bankruptcy. Department of Energy loan guarantees of $535M sparked an investigation. No wrongdoing has yet been uncovered despite a huge waste of government money. Lower production costs in China have been singled out as the critical factor in Solyndra's demise.
