If you're using the USB for data, then I think the cheapest way to do it is to put a USB isolator just behind your USB connector. It's not as effective as isolating the supply voltage, though, and you'll need an in-amp with good CMRR. I've done this in the past with an amplifier that I powered from the 12V supply of my computer.

If a DC/DC converter that can handle your entire amp's power is too expensive, you can alternatively place a resistor (1k or so, plus maybe an inductor / bead) in the ground line of the audio connection and use an instrumentation amplifier to recover the difference signal between the audio ground connection (at the other side of the resistor) and the audio signal lines. Depending on the power requirements, this might be a little expensive, however. Your entire circuit is powered from an isolated source then and there can't be any ground loops anymore. Given that your circuit doesn't communicate with the laptop via USB, there's no need for a digital isolator: Just place an isolated 5V DC/DC converter in the 5V power path right after the USB connector. Simulate this circuit – Schematic created using CircuitLab How is this normally done? I'm looking for a simple solution without overflowing the board with too many new components. I have used optocoupler and dc-dc isolators before, but I'm not sure how I should connect them in this context.

My question is, how can I implement a ground loop isolator for this application? I understand that a switch for lifting the ground on one side could be enough, but I want to find a solution that doesn't need a manual switch. The ferrite beads I use to separate digital devices from analogue (one side of the board is all analogue, the other digital, the ferrites go in between). The schematics below show how I'm powering the circuit. Otherwise, it works fine (like when transmitting audio from a phone and powering it from a power bank). When receiving USB power and receiving audio from a laptop, there is a ground loop. Manual Scan allows you to set the scan frequency and other transponder parameters.I'm working on an audio interface that utilises a microcontroller and a CS42448 audio codec. Network Scan performs a scan based on predefined network parameters.

Settings for controlling additional satellite equipment such as satellite selector switches.įull Scan performs a scan of all available satellite frequencies.

The TV will search for satellite services based on group of general settings. The frequency of the user band allocated to the TV or tuner. The number of the user band allocated to the TV or tuner. Each receiver or tuner is allocated one user ‘band’.ĭiSEqC installations allow you connect to multiple satellite dishes or LNBs if you have them, and to select between them using the TV control.įixed Antenna is usually the simplest installation type, where there is one satellite dish and LNB. Single Cable installations enable delivery of satellite programmes for multiple receivers over a single coaxial cable.

Your satellite installation type may be Single Cable Distribution, Fixed Antenna or DiSEqC. You can decide the installation type and set up the tuning options according to setting mentioned below:Īllows you to select the Single Cable Distribution, Fixed Antenna or DiSEqC.
