I have been given a device at work to do some testing on. Basically an IC is becoming obsolete so I need to test a replacement part. Upon redoing the ESD checks, the device failed. I checked the ...

This USB micro B has 6 mounting tabs. If I ground none or only 1 of them, will it ruin the signal? There is a pad for the signal ground that is separate from the mounting tabs. Fyi USB 2.0 has a max ...

I am just hoping to get some best practices out of this discussion: I have two pieces of equipment that are located about 30 feet apart and bolted to a metal frame (chassis ground). They interface ...

I have a half-bridge strain gage sensor (pre-assembled product) with a 30cm cable, which I am trying to interface with my PCB containing a 24-bit ADC. The connector at the cable end toward the ADC (i....

The shielding on a cable is to avoid interference from the outside world however it is always tied directly to the GND pin. Not inside the cable itself but inside a device. Every single device I take ...

I have a device which has two sections of the PCB completely isolated form each other, but connected by an isolator IC (PN: ????). I think I need to shield the whole device for reducing EMI because ...

With HDMI or USB3.0/3.1, a cable assembly, in addition to the main braided shield, has multiple separate shields for each differential pair, here an example of a USB3.0 cable: Image source The inner ...

I am designing a new board, where I need to detect if the DC input jack for powering the board has been plugged and then disconnect the USB power supply. I also need to detect it with the uC in order ...

I have designed a simple PCB on EasyEDA; I am using USB 3.0 as a convenient means of providing power, ground and taking outputs from the magnet sensors (connected to the PCB) which will be routed to ...

I'm new to Mixed-signal design and I'm having trouble deciding how to connect my digital and analog ground. I'm doing a 4 layer design, so I have a split ground plane. As I understand, since I'm ...

I have designed multiple small PCBs for personal projects, and have used USB ports many times for an output. I have always wondered if it is a good idea to connect the two mounting holes for the USB ...

I would like to ask for advice on shielding the following setup. I have a measurement target sitting inside a Faraday cage, connected through a shielded cable to a measurement circuit. The cable ...

The Datasheet provies an example configuration for when the device is powered from the bus, and shows the bus Vss connected to ...

Currently, we're trying to carry out electrophysiological recordings from the mouse brain using Open Ephys acquisition box and a silicon probe, and we are suffering from severe noise in probe signals. ...

I'm making a 5 volt portable regulated power supply (using LM7805 regulator IC) for Arduino UNO. I'm planning to use a USB connector as its output socket, this way I can just plug and power the ...
