USB Type-C PD 3.0 Specification, Charging and Design - EDN
Jun 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 increments as small as 20 mV over ...
Audio levels, dBu, dBV, and the gang: What you need to know
Apr 18, 2017 · Here’s what you need to know. First off, you need to know that I expended significant effort to avoid naming this article “ dB or not dB, that is the question ”. But seriously: The vast majority of line-level analog audio interfaces fall into two categories: Advertisement. Unbalanced, using “RCA” connectors, at a so-called “-10dBV ...
Cross Sectional Area Of Wire: Formula & Calculation - EDN
Nov 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 ...
Automotive HVAC & Cabin Climate Control System Basics - EDN
Dec 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 considered one of the big features, but today ...
PAM4 Basics: Modulation, Signaling and Encoding - EDN
Jan 14, 2016 · The result is four signal levels instead of two, with each signal level corresponding to a two-bit symbol. The PAM4 signal looks like trace M+L/2 in Figure 1. At the lowest level is 00, followed by 01, 10, and 11, respectively. PAM4 indicates pulse-amplitude modulation, with the “4” indicating four levels of pulse modulation.
Setup and Hold Time Basics - EDN
Apr 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.
Fundamentals of I3C interface communication - EDN
Dec 5, 2022 · Advertisement. I3C is a new serial communication protocol for embedded systems that offers significantly higher data throughput and more advanced features than I 2 C. With I3C, engineers and designers can improve the performance of their designs while also adding in new features like hot-join, in-band interrupts (IBI), and high data rate (HDR ...
USB 3.0—Everything you need to know - EDN
Mar 11, 2015 · USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for computer connectivity. Among other improvements, USB 3.0 adds a new transfer mode called “SuperSpeed” (SS), capable of transferring data at up to 5 Gbits/s (625 MB/s), which is more than ten times as fast as the 480 Mbit/s (60 MB/s) high speed of USB 2.0.
A closer look at the first made-in-China 5G chip from Huawei
Sep 5, 2023 · Figure 1 The Mate 60 Pro smartphone is reportedly built around the first made-in-China 5G chip: Kirin 9000S. Source: Huawei. Advertisement. The reports suggest that Huawei’s new SoC comprises four high-performance cores, four energy-efficient cores and the Maleoon 910 GPU, and that the SoC is most likely built around the Armv8a ISA.
