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 …
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.
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.
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 ...
A guide to using FETs for voltage controlled circuits, Part 1
WEBOct 13, 2017 · The answer is yes (e.g., VCR11), but it turns out that virtually any other FET (e.g., JFET and MOSFET) can be used as a voltage controlled resistor. Basic voltage controlled resistor (VCR) circuits. One of the simplest uses of a voltage controlled resistor is an electronically controlled attenuator or “volume control”.
Top 10 Uses Of The Internet - EDN

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 ...
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.
Gate level simulations: verification flow and challenges - EDN
WEBMar 5, 2014 · Simulations are an important part of the verification cycle in the process of hardware designing. It can be performed at varying degrees of physical abstraction: (a) Transistor level. (b) Gate level. (c) Register transfer level (RTL) Advertisement. In many companies RTL simulations is the basic requirement to signoff design cycle, but lately ...
